I'm trying to reinstall angular-cli tool to get the newest version. I did upgrade the graceful-fs, tough-cookies and lodash before installation. Now when I try to install angular-cli globally it produces this error:

(node: 7736) Warning: Possible EventEmitter memory leak detected. 11 error listeners added. Use emitter.setMaxListeners() to increase limit

I'm running cmd.exe as an administrator, so I really can't find the solution what can be wrong with this one. Other global or local installations are successful.

  • Beyond running as an admin, another reason npm may not be able to write to those files is that they are in use somewhere. Maybe check for that? Commented Sep 20, 2016 at 16:39
  • Nothing opened. I tried to install it without running anything and without any unuseful services or processes. I tried the newest Kali Linux (debian) too, but nothing. Still the same error. Commented Sep 20, 2016 at 16:50

I tried in many ways but nothing was working for me when I installed Windows 7 on a virtual machine and installed the latest Nodejs on it. Then using npm I installed angular/cli and everything is working well on that windows 7 :)

Even in windows 7 in actual pc it's working well so I guess it has some problems with Windows, mac or Linux version and Windows 7 is most effective for it...
