A minor, but frustrating bug. While working on Rogger, I came across the following problem while bundling my local Rogger into a test project:
The gemspec at /Users/siawyoung/github/rogger/rogger.gemspec is not valid. The validation error was 'rogger-0.1.1 contains itself (rogger-0.1.1.gem), check your files list'
I was quite confused. I checked the gem file but nothing inside seemed like a reference to
I tried building the gem:
$ gem build rogger.gemspec WARNING: See http://guides.rubygems.org/specification-reference/ for help ERROR: While executing gem ... (Gem::InvalidSpecificationException) ["rogger-0.1.1.gem"] are not files
The same error happened.
It turns out this happens because the
gemspec gets the list of files from the
`git ls-files -z`.split("\x0")
command. I happened to check the gem file
rogger-0.1.1.gem in, which was why this error was occurrring. Removing it, then, fixed it:
$ rm rogger-0.1.1.gem $ git commit -am "Remove rogger-0.1.1.gem" $ git push
