Executing npm install never finishes

[markzolotoy]

After cloning the project I am running npm install. Here is what I get
PS K:\Project1> npm install
npm WARN tar ENOENT: no such file or directory, open 'K:\Project1\node_modules.staging\nan-1c7803b7\doc\new.md'

And the command is not finishing.

Actually it did finish. Should I be concerned with errors?

I guess, I should be because next command did not work at all:

PS K:\Project1> npm run start

[email protected] start K:\Project1
npm run ng -- serve --port 5555 --aot

[email protected] ng K:\Project1

Can you please help?

Thanks

I had the same experience yesterday. Didn't finish. Aborted. Retry didn't work. Aborted.

What are your node and npm versions?

[markzolotoy]

Node - v 8.9.4
npm- 5.6.0

[jvitor83]

Guys, i am really sorry, but i wan't able to reproduce your problem.
I even reinstall node and do a git clone, but it worked just fine.

Can you please try to clear the cache, or even reinstall node and try again?

[markzolotoy]

Which cache to clear?

[jvitor83]

npm cache clean

https://docs.npmjs.com/troubleshooting/try-clearing-the-npm-cache

[markzolotoy]

Did not help.

Hi, try this please.

rm -rf package-lock.json 
rm -rf node_modules
npm cache clean --force
npm install

[markzolotoy]

PS K:\Project1> rm -rf package-lock.json
Remove-Item : A parameter cannot be found that matches parameter name 'rf'.

• rm -rf package-lock.json

[jvitor83]

1 - DELETE the file package-lock.json
2 - DELETE the directory node_modules
3 - RUN npm cache clean --force
4 - RUN npm install

[thomascayne]

I'm marking this as resolved (on my part). @markzolotoy , maybe you can try this: I deleted my node_modules folder; followed the installation steps using npm and it still hangs, again.

After it failed, this time I ran yarn [install]. Other than warnings for peer dependencies all packages were installed.

npm run start and ng serve now works.

@jvitor83 great job on this project. Beautifully done. Thank you!

[jvitor83]

My guess is that the package-lock.json is causing the trouble.
I think the 4 steps i put solve the problem.
@markzolotoy, open it again if not works for you.

[markzolotoy]

Yes, these four steps helped. Thank you! For the future reference what exactly it was? I do get a few warnings:
WARNING in ./node_modules/ionic-angular/util/ng-module-loader.js
27:11-36 Critical dependency: the request of a dependency is an expression

WARNING in ./node_modules/ionic-angular/util/ng-module-loader.js
37:11-36 Critical dependency: the request of a dependency is an expression

Is it critical?

@markzolotoy this not problem, you can see here explanation.
