如何从github pip安装特定日期

Question

I need to install with pip from a git hub but wanted the repository from May 4th. Can anyone help me on that?

for instance if I want to pip install a repo's specific branch I can use below command :

pip install https://github.com/user/repo.git@branch

but don't know how get it by date other than branch name?

Answer 1

Well, you can replace <branch> with a desired commit <sha-1> . I've just checked it with bpython:

$ pip install --upgrade --user git+https://github.com/bpython/bpython.git@f2014dbae31313571cc9c26f51a14f4fda09d138
Collecting git+https://github.com/bpython/bpython.git@f2014dbae31313571cc9c26f51a14f4fda09d138
  Cloning https://github.com/bpython/bpython.git (to f2014dbae31313571cc9c26f51a14f4fda09d138) to /tmp/.private/alex/pip-tQcJmV-build
  Could not find a tag or branch 'f2014dbae31313571cc9c26f51a14f4fda09d138', assuming commit.
...

Another question is how to get a commit for a given date.

The first option is to open a browser, find an appropriate commit and manually form a proper URL for pip install . Actually I used this way for the example above.

But you may want to automate things. I would do a local shallow copy of a given repo from github:

git clone --depth 10 --single-branch --branch master https://github.com/bpython/bpython.git

(take only 10 last commits from master branch of bpython official repo)

Then, determine what commit satisfies the date restrictions:

COMMITID=$(git rev-list -n 1 --before '2016/04/07 16:36:15 2016 +0000' HEAD)

Then, use the commit id in the pip install command:

pip install --upgrade --user git+file:///tmp/.private/alex/bpython@${COMMITID}

Answer 2

You could clone the repo, checkout the date you want locally and pip install in dev mode:

git clone https://github.com/user/repo.git
cd repo
git checkout `git rev-list -n 1 --before="2016-03-03 13:37" master`
pip install -e
