Answer 1

Unfortunately, the Angular CLI sometimes has some issues on Windows machines. Please have a look at the following thread for some possible solutions which I tried and worked: https://github.com/angular/angular-cli/issues/1349
Unable to find .angular-cli.DELETE file under C:\Users\\AppData\Roaming\npm\node_modules
hence I have deleted the entire node modules folder and did npm cache clear and then tried. it worked

Answer 2

I had the same issue, so I tried to install it using the node.js command prompt instead of the default one and it worked.
I hope it can help somebody else.

Answer 3

For me the problem was caused by running the npm install in Powershell. Running in a traditional command prompt fixed the issue.

Answer 4

Running Node command prompt as an administrator worked for me.

Answer 5

Try this (for mac users)
sudo chmod -R 777 <project-directory-name>
For example
sudo chmod -R 777 webProject1
