truffle init problem

[m888m]

After installing truffle, and trying to launch it with truffle init, I get the following errors:

Note that before launching truffle, I did npm rebuild node-sass , but still get the corresponding error.
Please help

[tcoulter]

It looks to me like truffle wasn't properly installed (i.e., an npm issue). Do an npm uninstall -g truffle and then an npm install -g truffle and see if that solves it.

[m888m]

Thanks a lot Tim! Solved it :+1:

[parvez99]

Hi Tim,

I am new to truffle and trying to build my first dApp. I have an Ubuntu 15.04 VM setup with Nodejs 5.10 and testrpc ethereum client installed as instructed on the website ( http://truffle.readthedocs.io/en/latest/getting_started/project/ ).

After running $ npm install -g truffle when I execute truffle init, it does not seem to do anything at all . I am not able to understand what the problem is. Could you please tell me a few things that I could try. Thanks.

[Akiiki]

Hi Tim, Please share your screenshot. Also truffle creates the project folders and files in the directory you run the truffle initcommand. For example if I navigate to Documents using cd Documents in my terminal and run the truffle initcommand, It will create the project files in Documents folder

[parvez99]

Hi, Thanks for the response. I have it resolved. There were some persmission issues with the folder where I was executing truffle init command. But there's one thing that I notice different. I am follwing https://www.youtube.com/watch?v=GPP6uAq15d8 video where, at 1:54 there's a file called 'app.json' explained as very important for configuration purposes.. But after initializing truffle, I accessed the project in atom and do not see the file called app.json . Also there's no config folder instead there's an environment folder. Is this an upgrade change or am I missing something. please comment as it'd be helpful. Thanks

[danielrussellLA]

I had a similar problem. I ran npm i -g truffle and then when I tried to run truffle init I got an error: zsh: command not found: truffle. What solved it for me is to create a local node_modules with truffle installed in it, and then run that copy.

1. run npm init and make a new npm project
2. run npm i truffle
3. run ./node_modules/.bin/truffle init and it should work

unfortunately, with this method, you'd have to call all commands by prepending ./node_modules/.bin/truffle to the command

[drewesk]

@danielrussellLA thanks for something that works, turned that into an alias so I could pretend that I was directly running the truffle command like a real boy.

[danielrussellLA]

Glad it worked for you @drewesk!

I had a problem with truffle init. I end up having an error

I have tried uninstalling and installing truffle as @tcoulter mentioned, but now luck.

[cgewecke]

@vamshirapolu There's more about this problem over at #766. At the moment init requires a working internet connection that can connect to github over https. If you're behind a proxy, you might see additional errors although there some work arounds suggested in that thread.

Ultimately we should remove any network connectivity requirements for truffle init. Opening an issue to that effect right now.

[vamshirapolu]

Thanks @cgewecke for the quick reply. As suggested, I did a git clone of truffle-init-default, now its working fine.

I tried to unbox pet-shop (screenshot attached).It's says downloading... but the folder remains empty.

[RaynHarr]

I am getting stuck at the unbox command, any ideas would be much obliged:

[CruzMolina]

Hey @RaynHarr, can you see if npx [email protected] unbox pet-shop works?

[RaynHarr]

Wow, @CruzMolina ! That worked, thanks! What did I do exactly?

[CruzMolina]

Nice. Have you tried uninstalling and installing truffle? (npm uninstall -g truffle && npm i -g [email protected])

npx is a package runner that temporarily downloads an npm package into a local cache and runs your package from there (https://www.npmjs.com/package/npx)

[CruzMolina]

Some users have reported issues in the past after using sudo to install and uninstall truffle, although maybe that's not something you've done.

Are you using a node version manager like nvm or n? Just trying to think off hand would else could be causing your issue.

[RaynHarr]

I did try to uninstall and reinstall, but was getting same result. 'Sudo' and 'nvm' or even 'n' are all not in my lexicon at this point, to show you how green I am. I must be missing something really basic and fundamental because I can't find anything on google about this and you're the first and only person to reach out after hours of scouring for some sort of clue. I really appreciate the quick fix!

[CruzMolina]

Huh. What version of node & npm are you using?

I can tell you're on a MacBookPro (I am too! macOS High Sierra 10.13.6), although I doubt what you're encountering is OS-specific.

Meanwhile, instead of having to use npx to download & then run truffle every time, you should be able to npm i [email protected] locally and then run npx truffle <whateverCommand>. Actually, I'd be interested in seeing if that works. It shouldn't download truffle again before running, instead it should just access what you locally installed in your local node_modules folder.

[RaynHarr]

node 10.15.3 and npm is 6.4.1. Using Sierra 10.12.6. I'm not entirely postiive I understand how to do it locally, but here's what I just tried, hopefully this provides some insight:

[CruzMolina]

Thanks for sharing that!

Looks like saving locally w/ npm & accessing the local node_modules truffle works.

I suspect something is incorrectly configured w/ npm global installations.

This troubleshooting tutorial _might_ be what you need: https://medium.com/@jagatjyoti.1si13cs040/npm-g-install-npm-package-not-working-as-desired-why-why-why-19795abf0b59

This should get you back on track and make npm i -g truffle work so you can just run truffle commands normally w/o npx (otherwise you would have to install truffle locally in every different truffle project directory 😭 )

[RaynHarr]

I'm a little confused. (a lot really) I'm staring at the 'compilation failed' script at the bottom. Am I missing something? Or is that where the article link you provided is supposed to help troubleshoot me out? I have to admit, the article is also going way over my head. Wondering if there's a more basic tutorial I should be going through to have a better understanding of what exactly is going on here? I'm trying to learn through these DAPP University videos, but only moving an inch before I hit yet another wall. Any advice would be greatly appreciated, I'm already so grateful for the time you've put in thus far @CruzMolina !

[CruzMolina]

No problem @RaynHarr !

I should have clarified, that compilation error you saw at the bottom of your screenshot has to do with a missing semi-colon at the end of a statement in the smart contract you're trying to migrate.

I was more just trying to troubleshoot why truffle isn't working for you globally once you npm i -g truffle.

I'm assuming you've taken a look at the pet shop tutorial (https://truffleframework.com/tutorials/pet-shop)?

[RaynHarr]

@CruzMolina Ahh yes, a true newb mistake. I also ran into another issue where the tutorial was having me name a function the same as the contract it resides in, which apparently Solidity doesn't allow anymore? I think I just need to find a better tutorial. I appreciate your walking me through this. Cheers!

[CruzMolina]

Hmm, I believe the tutorial I linked has the contract code updated to not include a function of the same name. Maybe it's missing the expected constructor function for solidity 0.5.0 and above. I'll take a look.

Thanks for not giving up with this! This is valuable feedback. We really want to make it as easy as possible for newcomers to pick things up and get started.

[RaynHarr]

Oh no! I meant the DAPP University tutorial I've been going through, I haven't walked through the entirety of the link you sent, I will give that a try and let you know how it goes!

[CruzMolina]

Ah, I wondered that. Yeah, I just tested the tutorial code and it compiles fine on my end. Let me know if it's otherwise on yours.

[RaynHarr]

ok @CruzMolina so I was moving along swimmingly until I hit the 'truffle test' command where I ran into this error. I've done everything up to this point that the instructions asked. Any ideas?

[CruzMolina]

@RaynHarr do you have Ganache running in the background?

[RaynHarr]

Ay aya ay, another embarrassing mistake. Ya looks like it crashed on me in the background, I had it going for about a week so I'm not surprised. Would have helped to check to before throwing up another issue on here. Thanks @CruzMolina !

[RaynHarr]

Ok, I think I've scrubbed all the newb errors up to this point. I've gotten the page up and running with all the dog pictures, however when hitting the adopt button, I'm getting these errors:

This look familiar?

[CruzMolina]

What's your truffle-config.js settings? Are you using truffle console, truffle develop, do you have Ganache running in the background? Metamask connected to the proper network?

[RaynHarr]

Ganache is running, Metamask hooked to port 7545, i'm using npm run dev. Truffle-config was untouched by me, but is showing same as metamask network:

[CruzMolina]

Ah, so I believe you need to specify Metamask to connect to network_id 5777 (Ganache's default) in the Metamask settings somewhere.

If that doesn't work, try changing the truffle-config.js network_id to 5777 instead of "*". (This shouldn't be the problem though).

Oh, so this probably means we need to update the Metamask screenshots to show the new Metamask UI!

[RaynHarr]

Hmm I'm getting the same error after trying both of those solutions. Is it related that my URL is 'localhost:3000' and not 127.0.1.7545 (shootin' in the dark here hahah)

[RaynHarr]

Also, I'm using the Brave browser, not sure if that has any significance...

[CruzMolina]

Hmm, no the local server being run on 3000 shouldn't be an issue.

With Ganache running, you could try doing a migrate --reset. Might be that you have artifact files that were migrated to an older instance/network of Ganache that you've since cleared (would happen by closing down Ganache).

[RaynHarr]

Ok! Slowly but surely, truffle migrate --reset worked. but now Im getting a failed transaction:

[CruzMolina]

Hmm, hard to say without seeing your completed contract code.

Can you make sure your contract code is the same as the tutorials? I'm also assuming you were able to import your Ganache wallet key correctly and have ether to transact with.

[RaynHarr]

Ok, I did it finally! I'm not entirely sure what the fix was, I'm pretty sure it had to do with my Metamask setup though. Somewhere between me switching to the main network and back to 7545 and selecting this Account 2 that I'm fairly certain wasn't there prior.

Didn't touch the code really, left Ganache alone, and my Account1 had Ether in it the entire time. Regardless this is has been a really good lesson on how everything interacts with each other, I appreciate the hand-holding until the end!

[CruzMolina]

No problem, congrats!

Hi to all,

don't know if this is a truffle init issue but I get this...
When I try to migrate my Token smart contract (using Openzeppelin ERC20) I want to migrate using a custom script for initializing constructor parameter but I get stuck somewhere:

2_initial_migration.js

Deploying 'myToken'

---

Error: Error: Error: * Deployment Failed *

"myToken" hit a require or revert statement somewhere in its constructor. Try:

• Verifying that your constructor params satisfy all require conditions.
• Adding reason strings to your require statements.

at Object.run (/usr/lib/node_modules/truffle/build/webpack:/packages/truffle-migrate/index.js:92:1)
at process._tickCallback (internal/process/next_tick.js:68:7)

Truffle v5.0.25 (core: 5.0.25)
Node v10.15.3

FYI I can't find webpack anywhere nor truffle-migrate (locally or unders /usr/lib/...)
I have upgraded to Truffle 5.0.25 and I got this issue already with previous installed version (5.0.19)
and I use Node v10.15.3 while coding in Ubuntu Virtual machine with Virtual Box.

In this case I use Ganache Gui (or cli depends on which VM i work).

This is the constructor of myToken...

constructor (uint _quantity, uint _price, uint _ethconv, uint _fees, address payable _codex, address payable _to) public {

    owner =  msg.sender;
    codex = _codex;
    quantity = _quantity;
    price = _price;
    ethconv = _ethconv;
    seller = _to;
    fees = _fees;

    initialSupply = _quantity;
    ethPrice = _price * _ethconv;

    transfer(msg.sender, initialSupply);
}

And this is the migration script:

var myToken = artifacts.require("myToken");

let quantity = 100;
let price = 50;
let ethconv = 1;
let fees = 45;

owner = "0xbFe32eD630d3dBEFFa7Fa1dc38aA3108B8df840c";
codex = "0x36373E9d3A70c971D4D04b09697DA7d337204CDa";
seller = "0x3F3dEeA4877D97c98f610b5BE580DdA83dBC5C36";

module.exports = function(deployer) {
deployer.deploy(myToken, quantity, price, ethconv, fees, codex, seller, {from: owner});
};

@vinay1011998 I hope this answers your question: First you'll need to install nodejs at https://nodejs.org/en/. I would go for the LTS version. Npm comes with nodejs - it's nodejs's package manager software. Once installed, go into a folder and type npm init and hit enter a bunch of times on the prompts. There you go - you've created a new npm project. You'll see that a package.json file has been created in your folder - this is a file that you can use to manage your dependencies for your npm project. At that point you can install truffle with npm i truffle --save - you'll see that your package.json file has a new block called dependencies with truffle in it. There will also be a node_modules folder with the files for truffle library in it. then run ./node_modules/.bin/truffle init to start truffle at that point. see more here https://docs.npmjs.com/cli/init
