Upgrade Angular-CLI on Windows 10 with beta.17 fails to run

[lekova]

Tried to do the upgrade from beta.10 to beta.14 described in the wiki page and got a problem where the installation process is successful however I cannot run ng --version.

After couple of days I tried again (we are at beta.17) so I followed the same steps

• node update
• npm uninstall angular-cli -g
• npm cache clean
• npm install angular-cli@latest -g

I get the same problem as before:

Maybe you missed version property in angular-cli.json file.
It should be updated to 1.0.0-beta.14 or 1.0.0-beta.17 as well.

Wait, is that inside the project? Since the upgrade process requires you to make a new project, you should do it outside of the existing project.

The test folder is empty. I tried to create new project inside it with ng new test-project. Just put ng -v there to demonstrate that ng is not running. Sorry for the confusion!

Hm.... this error can appear if there's a node_modules folder with an older version anywhere in the folder hierarchy. Do you get the same error if you do this in, say, C:\test-folder\?

@filipesilva, that is exactly the problem I had. There are projects with an older version in the folder tree where I was trying to install the latest angular-cli. So I did as you suggested, cd to C:\, uninstall, cache clean and install latest. Verified with ng new and ng serve. Thanks!!!

Glad to hear it's sorted!

#2178 should have sorted this scenario overall, but if there's a older ng install up in the tree that one will be used instead.
