Question

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了）。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:

我有一个运行Python 2.7.15和Python 3.6.5的Fedora 26系统

我是Python的新手（刚刚开始学习它），所以请原谅无知。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。他们似乎都没有解决这个问题。我还应该注意到我在其他帖子中读过，运行pip作为sudo是一个坏主意（某些东西）我在尝试安装大熊猫时做了，因为我没有权限（同样，我稍后会读到这是一个坏主意）。感谢任何帮助。

Answer 1

尝试将PyCharm社区作为一个ide。他们有一种简单的方法来安装和卸载软件包。您还可以查看管理当前在虚拟环境中安装的所有软件包。

Answer 2

尝试以root授权运行它

    sudo pip3 uninstall numpy

大多数情况下，它应该可以工作。

Answer 3

我对numpy有类似的问题，我只需要使用apt（在您的情况下为yum）中删除软件包。尝试做：
sudo yum remove python3-numpy

Answer 4

这可能是一个解决方案：

对于python3：

sudo pip3 uninstall numpy  # pip3

对于python：

sudo pip uninstall numpy

或使用：

sudo apt-get remove python-numpy

我希望这会有所帮助。
