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
module.js:327
throw err;

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

module.js:327
 throw err;

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

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.

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

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.
