我从源代码安装了matplotlib，并从这里https://github.com/matplotlib/matplotlib
运行了python3 setup.py install
如何卸载此程序？ （我忘了在容器中做
这个答案How do I remove packages installed with Python's easy_install?显示了如何使用pip进行操作，但是我没有使用pip进行安装，而且我不确定该软件包的名称。
matplotlib未能成功安装，但它将许多文件复制到了build文件夹并认为已运行build。
这是安装时所打印内容的一部分：
python3 setup.py install

尝试通俗易懂的matplotlib，并确保您具有最新版本的pip。我曾经遇到过这个问题，并且已经解决了。
尝试python -m pip uninstall -U matplotlib，然后重新安装。
