Path pip安装ipython时出现环境错误

在我的Windows上尝试pip安装ipython时，我不断遇到此错误。皮普为熊猫和其他LIB工作

ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'C:\\Users\\Me\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\\LocalCache\\local-packages\\Python37\\site-packages\\jedi\\third_party\\typeshed\\third_party\\2and3\\requests\\packages\\urllib3\\packages\\ssl_match_hostname\\_implementation.pyi'

我也有同样的问题。对我来说，文件路径太长了。重命名东西（例如

PythonSoftwareFoundation.Python.3.7_3.7.1473.0_x64_qbz5n2kfra8p0

stuff）以缩短路径。

Windows Python安装程序允许您在安装或升级时更改最大路径长度，这将解决问题。您还可以查找change maximum path length Win 10以了解如何更改注册表。

我也有类似的问题。我将注册表项“Computer\HKEY\u LOCAL\u MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled”更改为1。

错误消息非常奇怪：。请尝试

pip安装-vvv ipython

并显示完整的错误消息。原始帖子已编辑。
