matplotlib - 在 Raspberry Pi 上卸载 matplotlib 时出现权限错误

问题描述

我正在尝试卸载我的 Raspberry Pi 上的 NOOBS 安装附带的 matplotlib 3.0.2 版本，以便我可以安装更高版本。但是我遇到了权限错误使用..

python3 -m pip uninstall matplotlib

但是如果我在这个命令前面添加 sudo，它会返回说没有找到要卸载的文件。下面是运行这两个命令的屏幕截图...

pi@raspberrypi:~ $ python3 -m pip uninstall matplotlib

我怎样才能解决这个问题？

解决方案

如果您只想更新软件包，请尝试：

pip install --upgrade matplotlib

或对于特定版本：

pip install 'matplotlib>=3.1.1' --force-reinstall

如果你真的想删除它，你可以通过获取包安装地址来手动完成：

pip show matplotlib

然后使用 rm -rf 手动删除它。

使用“setup.py”或任何环境安装软件包时，通常会导致此错误。这两种方法都没有留下足够的元数据让“pip 卸载”工作。
