Pip安装导致RecursionError

Question

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，我必须安装另一个软件，称为https://github.com/gbrammer/drizzle.git。Th安装总是会产生一个RecursionError。正如我运行的安装说明中所解释的那样

pip install git+https://github.com/gbrammer/drizzle.git

结果是

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_/

代码中的三个点代表三行代码的重复，这三行代码总是以相同的顺序出现，可能会导致RecursionError。

我已经尝试了不同的pip版本，但它没有改变任何东西。有谁有主意吗？

我也有同样的问题。对于我来说，唯一有效的解决方案是将sphinx降级到这里提到的<=1.5.6版本：https://github.com/ericmandel/pyds9/issues/53 (注意，当我遇到这个问题时，我已经有了astro-helpers >=2.0，所以解决方案是降级sphinx)只需这样做: pip安装sphinx==1.5.6，然后希望drizzle可以正确安装。
