pip安装和matplotlib库安装中的问题
提问于 2022-03-08 18:17:12
要安装matplotlib库，它的引用使用以下基础：
python -m pip install -U pip
python -m pip install -U matplotlib当我执行以下代码时：
(base) C:\WINDOWS\system32>python -m pip install -U pip
本警告的结果如下：

转到警告中的位置，查找以"~“开头的文件夹，如果发现任何文件夹，请删除它们并重新运行代码。

看起来你可能安装的不正确。试着执行
pip show matplotlib它是否显示已安装的版本？
如果您正在使用anaconda，则应该通过
conda install matplotlibStack Overflow用户

打开终端(即cmd)并转到有问题的文件夹，在您的例子中是c:\programdata\anaconda3\lib\site-packages，但在我的计算机c:\python310\lib\site-packages上。然后删除以~开头的所有目录，在我的示例中：
~ip
~ip-22.1.2.dist-info使用来自here的命令
for /f %i in ('dir /a:d /s /b ~*') do rd /s /q %i然后再试着升级pip，以确保现在一切正常：
python -m pip install -U pip有趣的是，我在我的macOS设备上和/usr/local/lib/python3.10/site-packages上也有同样的问题，问题文件夹是
~BB
~BB-0.2-py3.10.egg-info我可以轻松地移除它们，方法是转到该文件夹并运行
