Answer 1

我有类似的问题。我将注册表项"Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled"更改为 1。

Answer 2

我遇到了同样的问题。对我来说，文件路径太长了。重命名内容(例如PythonSoftwareFoundation.Python.3.7_3.7.1473.0_x64__qbz5n2kfra8p0内容(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。 您还可以查找更改最大路径长度 Win 10 以了解如何更改注册表。
