I am trying to install @angular/cli using the npm install -g @angular/cli.
But this try provides some error messages.

my node and npm versions are mentioned below, 

C:\WINDOWS\system32>node -v  
v 12.4.0

C:\WINDOWS\system32>npm -v  
'CALL "C:\Program Files\nodejs\\node.exe" "C:\Program Files\nodejs\\node_modules\npm\bin\npm-cli.js" prefix -g is not recognized as an internal or external command,
operable program or batch file.
6.9.0

I am using Windows10 operating system

When I am trying to install angular cli I got the following error messages

C:\WINDOWS\system32>npm install -g @angular/cli
'CALL "C:\Program Files\nodejs\\node.exe" "C:\Program Files\nodejs\\node_modules\npm\bin\npm-cli.js" prefix -g' is not recognized as an internal or external command,

    @rose, If @saketh advice will not work, try to run `npm cache clean` (according to npm [troubleshooting](https://docs.npmjs.com/common-errors#random-errors)) and then try to install again with your commands. – vanrado Jun 10 '19 at 11:31
  • I tried all these commands but the problem is still remaining.I can't find what is the exact issue. – Nanetta Jun 10 '19 at 11:48
  • is the type of processor a factor, when working with nodes and npm? – Nanetta Jun 10 '19 at 12:01

    @rose have you tried removing my files from recovery setting. As far as i know processor won't be a problem in recognizing the command the only problem is with the environment variables – saketh Jun 10 '19 at 13:01
  • Thank you all for helping me :) . – Nanetta Jun 12 '19 at 10:15

In this case the error occurs because of the semicolon at the end of the path in System variables.

ComSpec path C:\Windows\System32\cmd.exe;

Removing semicolon from the path works for me.
