我正在尝试在 conda 环境中安装一个名为 grizli ( https://github.com/gbrammer/grizli/ ) 的软件。在一个步骤中，我必须安装另一个名为 drizzle ( https://github.com/gbrammer/drizzle.git ) 的软件。这种安装总是会导致 RecursionError。如我运行的安装说明中所述
pip install git+https://github.com/gbrammer/drizzle.git
导致
Collecting git+https://github.com/gbrammer/drizzle.git
Cloning https://github.com/gbrammer/drizzle.git to /tmp/pip-req-build-ncjb9u8_
Complete output from command python setup.py egg_info:

RecursionError: maximum recursion depth exceeded while calling a Python object
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-req-build-ncjb9u8_/
代码中的三点代表三行的重复，总是以相同的顺序出现，可能会导致 RecursionError。
我已经尝试过不同的 pip 版本，但它没有改变任何东西。有人有想法吗？
