What does it mean BUNDLE_DISABLE_SHARED_GEMS: '1'?

Question

I found BUNDLE_DISABLE_SHARED_GEMS: '1', in .bundle/config. What does it mean?

Answer 1

Bundler takes some settings from the ~/.bundle/config file -- not from the shell env.

When set to true (default), the install of all gems will be to BUNDLE_PATH, regardless of whether those gems are installed in your system.

Bundler will not install gems already in system gems by default, so this is especially useful if you're trying to package up an application with all dependencies unpacked.

i assume 1==true in this case? – Dermott

Answer 2

That means that a "bundle install" will always install the gems into a local directory (defaults to .bundle), and use those, instead of system-wide installed gems.

I found that my .bundle/config file has BUNDLE_DISABLE_SHARED_GEMS set to true, but when I ran bundle, no gems were installed into local .bundle folder. BUNDLE_PATH env var is not set. – Suburban

Answer 3

I will say this much, I commented out BUNDLE_DISABLE_SHARED_GEMS: '1' on my system, and this prevented passenger standalone from serving a page, yielding an error starting with: "It looks like Bundler could not find a gem."

I am running all my gems except passenger in a locally bundled gemset.

From the bundler documentation:

Stop Bundler from accessing gems installed to RubyGems' normal location.
