Angular ng new returns package install failed error - compiler.umd.js missing

Question

I am trying to learn Angular and am following an online tutorial. However, I can\'t seem to get past creating a new project with ng new. I am running node v10.16.0 and npm 6.9.0

Answer 1

For some reasons when angular/cli (ng) run npm install by itself, it have problem with packages writing, so you can run

ng new yourProject --skipInstall=true

so angular/cli will not install any node packages and then run

npm install --force

to install it by yourself

Answer 2

I've faced like this issue and the solution was:

1. Go to Edit the system environment variables.
2. Under User variables for User ==> Path, Make sure C:\Users\user\AppData\Roaming\npm its above all, and make sure you are add current user directory.

Note: If you don't have current user directory you have to create it.

3.Under System variables ==> Path, Make sure *C:\Program Files\nodejs* its above all.

4. Open Command Prompt as user ==> npm cache clean --force.
5. npm install -g npm@latest.
6. ng new yourApp.
7. ng serve --open.

Answer 3

are you working offline? you need to be online, so that npm can download the dependencies for the project.
