可能引起上述问题的一个原因

标题是说缺少文件或者文件夹导致包的安装环境出现错误。我安装时具体报错如下：

Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory:
C:\ProgramData\Anaconda3\envs\qanlp\Lib\site-packages\numpy-1.19.1.dist-info\METADATA

具体路径也给出来了，缺少的文件也给出来了，就是缺少METADATA文件。
上述问题，可能是（包之间依赖环境需要的版本不同）重复安装了某个包，升级了不同版本的包或者是经历了安装环境初始化失败导致的找不到METADATA文件。上述两种情况我都经历过，且都报了这个错。具体是怎么导致的还不太清楚。

解决方案

既然问题说缺少此文件，就将METADATA文件，复制粘贴到报错时给的路径C:\ProgramData\Anaconda3\envs\qanlp\Lib\site-packages\numpy-1.19.1.dist-info\文件下就行了。如何得到METADATA文件，打开报错的路径C:\ProgramData\Anaconda3\envs\qanlp\Lib\site-packages\，找到numpy-1.19.1.dist-info文件夹之前的对应的版本甚至是相同的版本，一般就在该文件夹的上面。我的是之前依赖包重复装了低版本的numpy-1.19.0.dist-info，将这个文件夹下的METADATA复制粘贴到要安装的numpy-1.19.1.dist-info文件夹下即可。
