Global NPM package installed but command not found

问题:

I have globally installed two npm packages "download" and "enigmavirtualbox" via command line:

npm install -g download and npm install -g engimavirtualbox

I'm trying to use them in a batch file to bundle a single .exe file from my node project. For both, the commands npm list -g <packagename> yield the respective version output, independent of the present working directory.

However, inside my batch script the commands "download" and "enigmavirtualbox" cannot be found.

Running npm root -g yields C:\Users\<username>\AppData\Roaming\npm\node_modules and looking inside that folder I can see that folders for both packages are present.

What I have tried:

• Changing npm root as described here
• Uninstall and reinstall packages
• Add env. variable NODE_PATH to point to C:\Users\<username>\AppData\Roaming\npm\node_modules
• Add C:\Users\<username>\AppData\Roaming\npm\node_modules to PATH env. variable

The same setup works on my second computer (both run Win7 64bit). Is something wrong with my node installation, or what am I doing wrong?

回答1:

The executable binaries and .cmd files end up in C:\Users\<username>\AppData\Roaming\npm (minus the node_modules at the end) so adding that path to the PATH env. variable fixed the issue.

回答2:

If the above method does not work then use this command to explicitly set the path

npm config set prefix c:/Users/<username>/AppData/Roaming/npm
