galenframework installation failed

Question

I am trying to install Galenframework. I had GalenFramework earlier which I uninstalled using :

npm uninstall-g galenframework-cli

Now when I am trying to install it again using

npm install-g galenframework-cli

I get the following error message:

info Install exited unexpectedly

What is causing the problem?

Answer 1

Try installing with administration rights. Open a shell as admin

Also you could try the following thinks:

1. Disable any anti virus scanner
2. Change cache and retries:

npm config set cache-lock-retries 1000 npm config set cache-lock-wait 100000
