bundle package --all-platforms not finding cross-platform gems

[JJJJust]

I originally posted this as a comment to rubygems/bundler#5989 because of its broad title, but now think it's a different issue.

bundle package --all-platforms beginning with 1.16 doesn't seem to work properly, claiming that it can't find sources for gems for other platforms.

After deleting vendor/cache, and trying with 5686af6, it broke with:

d:\Development\Projects\bundletest>ruby -I D:\Development\Projects\bundle\test\lib -S bundle package --all-platforms
The latest bundler is 1.16.1, but you are currently running 1.15.4.

Updating files in vendor/cache
Could not find pg-1.0.0 in any of the sources

I still get the same error today on 1.16.3.

Reverting the change made to lib/bundler/installer.rb allows bundle package to work again both at the specified commit and on 1.16.3, but I haven't the foggiest idea why.

Same for me but also with bundler 2.0.2

Hei could some of you check whether rubygems/bundler#6113 fixed this? It was released with bundler 2.1.4. Thanks!

[deivid-rodriguez]

Actually, I think #4022 should fix this!

[deivid-rodriguez]

Assuming this is fixed by the mentioned PRs.
