pip bundle throws OSError when installing from a git repo

[minism]

I get this error every time on this specific git repo for some reason, no matter what the build directory (still fails if the build directory is clean). My pip version is 1.0.2.

$ pip bundle /tmp/test.bundle git+https://github.com/concentricsky/jingo.git#egg=jingo

@minism can you confirm if

pip bundle /tmp/test.bundle -e git+https://github.com/concentricsky/jingo.git#egg=jingo

Works for you (note additional -e arg).

[minism]

@pnasrat yes, the command is successful with -e.

OK that should give you a work around for now - will investigate root cause.

upgrading pip worked for me
version >1.2
