pip freeze generating invalid requirement URL for package on Git

[mwaterfall]

When installing a package from a Git repo on GitHub, I added the following in my requirements file:

-e git+https://github.com/mwaterfall/html2text.git@0aa79aa386348574709f9367b5d86fce79c7364e#egg=html2text-no-markdown

I chose the egg name myself (which I believe is okay) and consists of the repo name followed by the branch name. The commit specified is on the branch 'no-markdown'.

Running pip install -r requirements.txt installs it correctly.

However, when I run pip freeze > requirements.txt, pip reformats the url to:

-e git+https://github.com/mwaterfall/html2text.git@0aa79aa386348574709f9367b5d86fce79c7364e#egg=html2text-origin/no-markdown

If I then immediately run pip install -r requirements.txt again I get the following error:

Exception:

ValueError: ('Expected version spec in', 'html2text-origin/no-markdown', 'at', '/no-markdown')

I believe this is because of the forward slash that pip has put in the egg name (html2text-origin/no-markdown).

So I'm a bit stuck as I can't rely on simply outputting pip freeze to my requirements file anymore.

I'm running pip 1.4.1 and git 1.8.3.2. There were issues with git >= 1.8.3 which was resolved in pip 1.4, but I'm wondering if this is an outstanding issue.

Pip 1.3 appears to not do this-- it doesn't put branch information on the egg name. I'm having the same issue while using Pip 1.4 and git 1.8.3.4

[paulmelnikow]

+1. I'm seeing this with pip 1.4.1 and git 1.8.3.4.

I also hit this, and I confirmed it still happens in pip 1.5.

Actually, this looks to be a duplicate of issue #1083 and so can be closed, right?

[mwaterfall]

Yep looks like it — thanks! I'll close this so the focus can be on #1083.
