当我运行 pip install hypothesis[pandas] 时,我得到以下信息:
Collecting hypothesis[pandas]
Using cached https://files.pythonhosted.org/packages/36/58/222aafec5064d12c2b6123c69e512933b1e82a55ce49015371089d216f89/hypothesis-3.82.1-py3-none-any.whl
hypothesis 3.82.1 does not provide the extra 'pandas'
pip install hypothesis[django] 似乎有效,hypothesis.extra 有 django 但没有 pandas。知道pip install for pandas 和 numpy extras 发生了什么吗?
