Issue installing bower on windows

问题

I'm using Windows 7 64bit and I install Bower with

npm install -g bower

It seems to install correctly.

npm http GET https://registry.npmjs.org/amdefine
npm http 304 https://registry.npmjs.org/amdefine
C:\Program Files (x86)\Git\local\bower -> C:\Program Files (x86)\Git\local\node_
modules\bower\bin\bower
bower@1.3.3 C:\Program Files (x86)\Git\local\node_modules\bower
...

But bower is not working:

$bower
sh.exe": bower: command not found

$bower -v
sh.exe": bower: command not found

What could be wrong?

回答1:

Check if C:\Program Files (x86)\Git\local is added to your Path Environment Variable.

回答2:

Same problem but for me I had to add the Path Environment Variable that pointed to the AppData/Roming/ folder. I have no idea why node.js would install npm in the Roming folder. If I didn't have hidden folders turned on we never would have found it.

C:\Users\me\AppData\Roaming\npm;

Then npm works from Node.js command prompt, and bower works from GitBash.

Check your version of node, I was running on v0.10.15 then updated to v0.10.35 and that fixed the issue for me.
