我在尝试在Python 3.6.9环境下安装pycocotools时遇到了问题。
我的电脑是Windows 10上的Ubuntu 18.04。我创建了一个虚拟环境并激活它,然后想要安装软件包,使用了以下命令:
pip install <package> --user
当我安装Cython时,一切正常,但是当我安装pycocotools时:
pip install pycocotools --user
我遇到了以下错误:

Complete output from command python setup.py egg_info:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-build-mut7_bkf/pycocotools/setup.py", line 2, in <module>
from Cython.Build import cythonize
ModuleNotFoundError: No module named 'Cython'
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-mut7_bkf/pycocotools/
我不理解这个错误,因为cython已经安装,而且在安装期间没有出现错误消息。

当我使用时,问题仍然存在。
python3 -m pip install
但是,我有一些有趣的东西。在活跃的环境中:
@ : python3 -m pip --version
@ : pip 9.0.1 from /env/lib/python3.6/site-packages (python 3.6)
@ : python3 -m pip install --upgrade pip --user

所以,这个包被正确地下载和安装了,但是当我调用它时没有任何变化。我怀疑路径不同,但不知道如何解决。
有人能帮帮我吗?
最好的祝福,
克里斯
