从GitHub中的特定分支安装。 我需要指定鸡蛋吗？

Question

I want to install the 2.3 branch of PyMC .

I have tried with:

pip install -e git+git:://github.com/pymc-devs/pymc@2.3

and

pip install git+git:://github.com/pymc-devs/pymc@2.3

without luck. Do I need to specify egg information? If so why?

Answer 1

You have too many colons in your URL:

git+git:://github.com/pymc-devs/pymc@2.3
#  ----^

Just one colon is required:

pip install git+git://github.com/pymc-devs/pymc@2.3

or, in editable mode:

pip install -e git+git://github.com/pymc-devs/pymc@2.3

Provided you have a Fortran compiler installed that Just Works.

The #egg=<projectname> part is optional and only used to test for dependencies before downloading. It lets pip test if the package is already installed without needing to clone the whole repository.
