使用 pip 从 git 将 package 安装到站点包中

Question

I installed a Python package using pip from git. In order to achieve this, I added the command -e git+<link>#<egg> to my requirements.txt. Pip installs this package, but not in the way I would like to have it.

First problem: I use a virtual environment. Usually, packages end up in <env>/Lib/site-packages . This one does not, it ends up in <env>/src . This makes it more to difficult to import.

Second problem: The src folder also gets created within my actual project, the one I am working on.

Both things are different to installing packages from other sources like PyPI. Is there a way to install my own packages via git in the same way? I actual built a wheel and a tar.gz, but I don't know how to install them...

Answer 1

@AnthonySottile's comment pointed me into the right direction: The -e option makes the installed package editable, which is not what I wanted. It actually works without it! So if you want to avoid having src folders appearing everywhere - download from git without the -e option: git+<link>#<egg>

Unfortunately, I didn't find any documentation for this ... so feel free to post a more profound answer or add to this one.

The following format of specifying a git+https location in requirements.txt worked for me:

pycocotools@git+https://github.com/gautamchitnis/cocoapi.git@cocodataset-master#subdirectory=PythonAPI

But I had to install numpy and Cython first, so that the installation of that package was successful. setuptools was already installed, this might need attention too.
