以下错误是什么意思：AttributeError:module“importlib.\u bootstrap\u external”没有属性“\u w\u long”？

Question

最近在windows中通过conda安装了一个github包，该包创建了一个新的Python环境

每当我尝试在新环境中运行Spyder时，都会出现以下错误：

Error processing line 1 of C:\Users\cip18jjp\Anaconda3\envs\ox\lib\site-packages\matplotlib-3.2.1-py3.8-nspkg.pth:

  Traceback (most recent call last):

osmnx和github页面上给出的命令：conda config --prepend channels conda-forge conda create -n ox --strict-channel-priority osmnx

已解决：windows中的Path变量指向一些不同的Python文件位置

这是因为python和pip安装在不同的源上。欲了解更多信息，请查看以下帖子

using pip3: module "importlib._bootstrap" has no attribute "SourceFileLoader"
