Question

观察我如何用pip安装wstool，然后仍然无法从CLI调用它。我也把各种各样的路径放在那里。有人能看到我的错误吗？

bash-3.2$ echo $PYTHONPATH
/usr/local/opt/python/libexec/bin/python
bash-3.2$ sudo -H python -m pip install -U wstool

~ ls /usr/local/opt/python/libexec/bin/wstool
ls: /usr/local/opt/python/libexec/bin/wstool: No such file or directory

那么，我的路径错了吗？这似乎是pip安装的......

ls -l /usr/local/lib/python2.7/site-packages/wstool-0.1.13.dist-info/

Answer 1

pip没有维护已安装软件包的数据库。目录*.dist-info 是其数据库。目录wstool-0.1.13.dist-info存在时，pip认为已安装包。

删除dist-info目录以使pip忘记包并重新安装：

sudo rm -rf /usr/local/lib/python2.7/site-packages/wstool-0.1.13.dist-info
sudo python -m pip install -U wstool

Answer 2

不是直接回答您的问题，但我建议您安装Linuxbrew并让它为您构建您的软件包。在这种情况下，/ usr / local / lib / python2.7 / site-packages是标准的包站点，但是你的Python无法以某种方式看到它。最后一件事，你应该是python2，pip2而不是泛型python，为了安全起见。

为什么pip不适合我？
