Question

我正在尝试在conda环境中安装名为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。此安装始终会导致RecursionError。如安装说明所述，我运行

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_/

代码中的三点代表总是以相同顺序出现并可能导致RecursionError的三行的重复。

我已经尝试了不同的pip版本，但没有任何改变。有人有主意吗？

我刚遇到同样的问题。唯一适用于我的解决方案是将狮身人面像的版本降级为<= 1.5.6，如此处所述：https://github.com/ericmandel/pyds9/issues/53（请注意，当我遇到问题时，我已经有astro-helpers> = 2.0了，所以解决方案是在降低狮身人面像上只需执行以下操作即可：pip install sphinx == 1.5.6 然后希望毛毛雨将正确安装。

Pip安装导致RecursionError
