Ganache-cli: Unable to install and use ganache cli through npm, errors pop up!

[kunaldhariwal]

I literally cannot understand what the error says and what the solution is!

[Enigmatic331]

Try npm install -g --production windows-build-tools, which should install the required dependencies. You might also need to install Python (if it doesn't download the package for you).

Had the same error earlier when installing Ganache CLI v6.2.1 on my Windows 10 machine.

[kunaldhariwal]

@Enigmatic331 why does it need to install python though?

[kunaldhariwal]

@Enigmatic331 Thanks man! It's working fine and up running 💯

[davidmurdoch]

@kunaldhariwal Thanks for reporting this. I'm reopening because it was not my intent to require users to install windows-build-tools in order to use ganache-cli! I intended our native modules to be _optional_ dependencies, with fallbacks to pure-js versions, but that seems to not be what is happening here.

[chriszer]

In my Ubuntu I'm having the same error please help

[davidmurdoch]

@chriszer, what does running python --version output for you?

[AshutoshMahala]

I tried to install on Windows, Mac and Ubuntu. I'm getting the same error on all the platforms.
It would be great if it can be helped. and please Mac and Linux tags too for this issue as this is happening for all the platforms. Thanks!

[davidmurdoch]

@AshutoshMahala, when you run python --version what is returned?

[AshutoshMahala]

@davidmurdoch python 2.7

[davidmurdoch]

@AshutoshMahala It is python 2.7 on Mac, Ubuntu, and Windows? Is the error you are receiving on these platforms something like gyp ERR! command "...node.exe" "...node-gyp.js" "rebuild" or something else?

In need of help!!

[AshutoshMahala]

I'm now able to install it with --unsafe-perm.
Thsnk for help

[swkidd]

I solved a similar problem today, installing ganache-cli and drizzle, where msbuild was failing with MSB5014 'file format not recognized'. The problem was I had an older version of msbuild on my PATH that prevented visual studio 2017 from using its build tools. Once I had removed all references to C:\Windows\Microsoft.Net\Framework64\* from my PATH, where msbuild.exe is located, everything built correctly.

Note I found this solution after a lot of tweaking and messing with things. I had problems downloading windows-build-tools which were solved by uninstalling python (using add remove programs). I also made sure C++ tools were enabled in the visual studio installer, and added support for visual studio 2015 tools in the 2017 installer as well as support for python build tools. I cannot say if these steps made a difference or not.

[coderark]

I am getting the same error on Mac while installing ganache-cli, Python=3.7.0. How do I solve this?

[davidmurdoch]

@coderark, Python 2.7 is required to build the native modules required by some of ganache's transitive dependencies.

Alternatively, you can use the new ganache-cli@beta which removes all native modules from the build. To install run npm install ganache-cli@beta -g.

[coderark]

@davidmurdoch Thanks it worked 💯

[davidmurdoch]

Fixed in [email protected]

[raphadko]

I know this is a ganache-cli thread, but this is still happening when installing Truffle.

[davidmurdoch]

@raphadko are you installing Truffle from npm or from source?

having this problem while runnnig ganache-cli on ubuntu 16.04, seems like something is missing, please help

[davidmurdoch]

@fcooper98 sorry you are having trouble. Can you open a new issue for this?

[varioso1]

Having the same issue on mac. Python version:
Python 3.6.1 :: Anaconda 4.4.0 (x86_64)

Tried the beta (npm install ganache-cli@beta -g), tried git clone but to no avail: throwing a long list of errors.

Appreciate your help.

[davidmurdoch]

@varioso1 You'll need to make sure you are using python 2.7 on your system to build native modules. With that said, ganache-cli should still install and work even if the native modules fail to install.

Can you paste the errors here?

[varioso1]

@davidmurdoch Thank you for your response. I started installing 2.7 but then restarted my system and was able (by the looks of it) to install ganache by running sudo npm install ganache-cli@beta -g. Then I got the following error at npm start though:

missing script: start

But that might be something on my side?

Otherwise, I am able to use ganache-cli without any problems. I wanted to use the GUI though (which is available only with python 2.7, right)?

Thank you!

@varioso1 it looks like you've installed ganache-cli@beta globally. To start ganache, you should be able to issue the command ganache-cli directly into your terminal! I generally recommend uninstalling any previous global installations you have whenever you try a different version too.

@nicholasjpaterno thank you. That's true, I've installed it a couple of times on top of previous installations (only deleting the ganache folder) which might cause some problems, I guess. Otherwise, I've been using ganache-clisuccessfully, deploying contracts. Haven't been able to open up the GUI though. Not sure if there is a way to open it without cloning the GitHub repo.

Any idea why I'm getting the missing script: start error? Maybe not an issue or not for this thread, though. Thank you.

@varioso1 Unfortunately, right now ganache is split among a few different repositories. The command you issued will only install ganache-cli globally. For the GUI you'll want to head over to https://github.com/trufflesuite/ganache/releases to download the latest pre-built executable of Ganache GUI for your OS!

@nicholasjpaterno Got, it, thank you. Just downloaded. Working fine. Cheers.

Please help !

@RajeshPrasad031 Can you try simply running npm install ganache-cli and let me know if you still get an error?

And if you do still get an error, can you paste the last 100 or so relevant lines of the npm log here?

p.s., you should upgrade to [email protected] if feasible.

@davidmurdoch thanks man. I installed it from it's official website "Trufflesuite"
