Bower - error when installing package “Arguments to path.join must be strings”

问题

I just created a node project and am trying to install jquery using bower.

bower install jquery

I get the following error:

bower jquery#*              not-cached git://github.com/jquery/jquery.git#*
bower jquery#*                 resolve git://github.com/jquery/jquery.git#*
bower jquery#*                   error Arguments to path.join must be strings

System info:
Bower version: 1.3.7
Node version: 0.10.29
OS: Windows_NT 6.2.9200 x64

I've tried installing other packages and they fail with the same error. I've got a pretty vanilla setup as far as I know. Running Windows 8.1 x64. Can't seem to find relevant info about why I'm getting this error.

回答1:

Fix: Clear cache and update to Bower 1.3.8.

This is what's going on:

The tmp package updated it's API to return a cleanup callback in addition to just the directory name. Q then squashes the two arguments to the callback into an array, while bower expected just a string for the directory name.

This causes "TypeError: Arguments to path.join must be strings" errors to appear, seemingly non-deterministic, because various spots attempt to use the _tempDir value (now an array) to join into a path.

semver ftw!

回答2:

For other people who are still running into this, this did the trick for me:

bower cache clean

回答3:

For me npm install -update bower was not sufficient.

I needed to install the version by specifing it explicit:

sudo npm install -q bower@1.3.8

and yes, I had to run this with sudo.
