Angular-cli: Cannot find module 'exists-sync'

[cre8]

1. OS? Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)
   os: Windows 10
2. Versions. Please run ng --version. If there's nothing outputted, please
   angular-cli: 1.0.0-beta.8
   node: 6.2.2
   os: win32 x64
3. Repro steps. Was this an app that wasn't created using the CLI? What change did you
   do on your code? etc.
   I updated to the latest cli version (beta 8). When I run ng outside the project it shows me all the options. But when I run it inside my project I get an error.
4. The log given by the failure. Normally this include a stack trace and some
   more information.

I hit this too and got around it by running a npm install

[scrivy]

I still get the same error after running npm install :-/

ng init

I did npm install in the nodemodules and it generated new project but when I typed
ng serve --port 4201 --live-reload-port 49153 It shows the same error again

go to angular-cli installed directory ex: C:\xampp\htdocs\foo1\node_modules\angular-cli run npm i

[crzyjcky]

I ran "npm install" twice:

1. For "ng new" to work:
   cd /usr/lib/node_modules/angular-cli
   sudo npm install
2. For "ng serve" to work:
   cd "your project folder"/node_modules/angular-cli
   npm install

[littleStudent]

just had the same problem on macOS
running npm install did solve it.

[KarlPurk]

Just hit this problem too. Should the readme be updated to mention npm install as this doesn't instil confidence for newcomers? The first thing the readme shows is:

ng new PROJECT_NAME
cd PROJECT_NAME
ng serve

and that doesn't work due to this issue.

[ghost]

try running npm install exists-sync --save-dev in the project folder.

[Codermar]

Re-installing the CLI (to beta8) and starting a brand new project, I had to do additional npm installs before I was able to run the app.

npm i -D exists-sync
npm i -D object-assign
npm i -D minimatch
npm i -D walk-sync
npm i -D through

[M4RTO]

you have to go inside the directory of angular cli , inside of node and npm install

[Codermar]

That's right, I had to do that too but still had to do the additional installs after ng new in the project itself.

[rijine]

got same problem, npm install --save works for me

[david-lee]

ran npm install and worked for me

[EdwinFernandoGarciaLozano]

npm install and worked for me
Thanks!

[juampi]

Thanks @crzyjcky ! Worked like magic.

[dtereshenko]

@crzyjcky It also solve my issues. Thanks!

[krisai]

npm i fix it for me

[madhusudhand]

I guess this is the problem with NPM itself.

ember-cli has a dependency "exists-sync": "0.0.3"
where as angular-cli has the same as devDependency.
npm install -g angular-cli doesn't install devDependencies of angular-cli.
But they should get installed inside ember-cli; But it isn't inside ember node-modules.

Same is the case with object-assign, minimatch, through and walk-sync.

[manuelfink]

@madhusudhand how than can the dependencies for angular-cli / ember-cli be installed?

[manuelfink]

However npm instal did not solve the problem for me. I do have to run it as root on mac sudo npm install which seems to be really bad practice for me.

[Rafi993]

In linux or mac OS you need sudo while running npm if you want to run without sudo you should use nvm or follow the instructions given in here. This is not an issue and it is not related to angular-cli

[Rafi993]

@cre8 please close the issue if it is solved.

[manuelfink]

@Rafi993 it seems to be that this is not resolves as of now.

• .beta8 is missing the above dependencies, which must be manually installed to get angular cli running and than be manually installed within every project.
• I do agree that root is necessary for installing global packages. However running npm within a project as sudo seems weird to me. Still I'm anyhow not even understanding why I need root privileges for a subfolder which belongs to my user. Maybe just a problem of my mac.

[PascalPrecht]

This comment https://github.com/angular/angular-cli/issues/1186#issuecomment-228691834 describes the actual issue very well.

@filipesilva are we planning to add those dependencies to dependencies ? Otherwise the command is simply globally broken.

[filipesilva]

Hi everyone, apologies for taking so long to address this issue. First of all, thank you for all the comments and proposed temporary solutions.

Reading through the thread allowed me to zone into the real issue - the way ng new ran npm. Turns out it was using a 2.x.x npm internally. This is why when you did npm install things just worked again, your global npm version was more recent.

Simply adding these missing dependencies to the project was not the solution, because the problem was that npm wasn't correctly installing them in the first place.

I created a PR that updates the local npm to 3.10.2. That should fix all these issues.

[warapitiya]

I get the same when ng new projectName

Ubuntu 16.04 LTS
Nodejs v4.4.7 LTS
npm v2.15.8

FYI: I manage to update npm and it fixed the issue. Thanks :+1:

[jackvial]

Updating to the latest version of npm then reinstalling angular-cli worked for me.

[rbinsztock]

Fresh install right now Windows 10
versions :

• node : 4.4.7
• npm : 2.15.8
  Can't create new project returning error :

module.js:327

So go in : C:\Users\senayar\AppData\Roaming\npm\node_modules\angular-cli

and run npm i

finally got the same problem running ng serve after this :

Updating npm was the solution : npm install npm -g

npm : 3.10.3

[Splaktar]

@senayar yes that is still needed until beta.9 is released if you aren't using the master version.

[filipesilva]

As @Splaktar mentioned, the fix will be out in the next beta (beta.9).

Meanwhile what you can do is to delete node_modules inside your project and run npm install. That should fix every missing module.

[msiddiqi]

Updating npm to the latest version fixed the issue for me too.

[rbnzdave]

fresh install of windows 10, new download of node.js, while it installed ng without a problem it hit the sync issue immediately. I've got no package.json file to run, just following a tutorial to

npm install -g angular-cli

ng help

and i get the errors.

[tieppt]

@rbnzdave scroll up, then install dev dependencies for angular-cli :up:

[ghost]

New shit happens, I downloaded the node 6.x.x latest version it works fine for the ng new project command, but when I type ng serve it pops up an throw error

Just do npm install in your project. That fixed it for me.

I did it in /node_modules and in my project, So I really don’t understand

[rbnzdave]

@tieppt yeah was going to do that today, was just pointing out that a fresh install of everything wasn't working either so wasnt just "update npm" :)

[rbnzdave]

using npm i -D [items] didnt work for me, i had to

npm install -g exists-sync
npm install -g object-assign
npm install -g minimatch
npm install -g walk-sync
npm install -g through

and now npm new reddit-clone is actually doing something for me. (following r33 tutorial mp4 from ng-book2. totally recommend)

--update : and now ng serve is failing from not being able to find 'exists-sync' think i've got bigger problems somewhere.

--update 2 : apparently a fresh install of node.js doesnt include an updated npm. ran

npm install -g npm

and then ng serve works fine. I'm almost ready to wipe out nodejs/npm completely and re-install just to see if that was the issue the whole time. if you are having issues, like me, and

npm -v 

doesnt get you at least 3.x.x etc, you will need to manually install npm to get the latest version.

[samirthebti]

Hi all :
This problem is seriously blocker any help !!

[ghost]

Ok, so to all the people who had this problem, please make sure you got the latest & current version of node installed (at this time : node : 6.2.2 and npm : 3.9.5) then install angular-cli by typing
npm install -g angular-cli (sudo if you get warns)
then go to /node_modules, find the angular-cli folder, and run npm install (sudo may be required)
then, start a project ng new projectname go into the new created project folder and type npm i.
Peace !

[mchamo]

@ddagone is there a dependency on node 6.2.2? I may have missed it, but, I don't see that stated on angular cli website or this git repo?

[ghost]

I haven't missed any dependecies, I haven't installed the correct version
of node

Upgraded to the latest npm 5.0.3 and had
angular cli cannot find module 'rsvp'
Going to node_modules/angular/cli and running nmp i fixed it but...

[BenRacicot]

I can confirm the issue from @ctrl-brk however I cannot get it to work by npm i the cli #showstopper

[phillipzada]

The following worked for me.

npm cache clean --force
cd node_modules\@angular\cli
npm i
cd ..\..\..
npm i
ng serve
