无法卸载numpy，

Question

新手上路，请多包涵

我正在尝试使用 pip 卸载 numpy （我还安装了 pandas ，但我似乎已经能够卸载它）。在 `numpy 的情况下，我得到以下输出。

 pip3 uninstall numpy -vvv --log pip.txt

Uninstalling numpy-1.12.1:
  /usr/lib64/python3.6/site-packages/numpy
  /usr/lib64/python3.6/site-packages/numpy-1.12.1-py3.6.egg-info
  Removing file or directory /usr/lib64/python3.6/site-packages/numpy
Exception:

During handling of the above exception, another exception occurred:

我有一个同时运行 Python 2.7.15 和 Python 3.6.5 的 Fedora 26 系统

我是 Python 的新手（昨晚才开始学习），所以请原谅我的无知。我已经看到了几个相关的问题（主要是处理 pip 安装而不是卸载。它们似乎都没有解决问题。我还应该注意到我在这些其他帖子中读到过将 pip 作为 sudo 运行是个坏主意（有些东西我在尝试安装 pandas 时做了，因为我没有权限（我后来又读到这是一个坏主意）。感谢这里的任何帮助。
