I was able to install nodejs version v10.7.0 and npm version 6.1.0 without any issues. Also installed angular 1.7.2 and typescript 2.9.2.I am getting this below error on trying to install npm install -g @angular/cli@latest.

I have tried all of the debug steps I could find online, including force clearing the cache and installing and uninstalling nodejs and adding my system32 folder to the PATH variable. Mostly followed this article I thought was very helpful - How do you install angular-cli for windows 7

I got to resolve the issue the problem is to remove the semicolon(;) from an end of the ComSpec path C:\Windows\System32\cmd.exe

You can open it by reaching: My Computer->properties->Advance->Environment Variables->System Variables

Here, add this on path

Image of System variable Note: I have encountered this problem while working with react js.

Go to

My Computer -> properties -> Advance -> Environment Variables -> System Variables

click on ComSpec and then click the edit button at the bottom and set the path of "ComSpec" equal to C:\Windows\System32\cmd.exe.

What fixed it for me was that my solution directory was on a different drive than windows

Creating my solution on my C drive solved the issue for me
