Cannot find module 'exists-sync'

OS? Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)
os: Windows 10
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
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.
The log given by the failure. Normally this include a stack trace and some
more information.

Mention any other details that might be useful.

Thanks! We'll be in touch soon.

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

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

ng init
module.js:327
throw err;

angular-cli: 1.0.0-beta.8
node v4.4.5
npm 2.15.4

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

    throw err;

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

I ran "npm install" twice:

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

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

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.

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

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

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

\Users\Martin\Documents\project\newProject\project\node_modules\angular-cli\node_modules

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

ran npm install and worked for me

npm install and worked for me
Thanks!

@rbnzdave

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

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

@tieppt

@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" :)

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.

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

@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?

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...

@ctrl-brk

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

The following worked for me.

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