How to change bower's default cache folder?

问题

On *nix, bower uses the ~/.bower folder for its cache (packages and so on).
I would like to change this to a different location.

The bower spec document from suggests that I configure the storage key in my .bowerrc.

I have created one in my project folder like so:

{
  "storage": {
     "cache": "~/blah/cached",
     "git": "~/blah/git_templates"
  }
}

When running bower install - i see that it still tries to save into ~/.bower.

Can anyone tell me what I am doing wrong here ? And/or if there is a different way to change the location ?

回答1:

I had the same problem, after some tries according the spec, I gave up...

So I reviewed bower's history on github and found:

Before v0.10.0, bower used config.cache (lib/core/ResolveCache.js) for its cache location
After that, satazor rewrote bower's core, now using config.storage.cache at the beginning, i bet the spec doc was written at this time. From the spec:

storage [object]

Where to store persistent data, such as cache, needed by bower. Defaults to paths that > suite the OS/platform. Valid keys are cache, registry, links, completion.

However, after this commit, satazor now uses config.storage.packages instead of config.storage.cache
After that, in the v1.0.0 release, the config is always set to config.storage.packages, but the spec has not reflected this change ever since

Solution

Export the environment variable bower_storage__packages

Use a .bowerrc such as:

{
  "storage":{
      "packages":"/path/to/cache"
  }
}

P.S.: I think that linking the spec doc in Google Docs isn't a good idea, maybe github would be a more sensible choice (since we can issue pull requests).

回答2:

What version of bower are you using? Bower 1.0.0 no longer uses ~/.bower. It follows the XDG spec, http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html

The "storage" property is only valid for 1.0.0.
