问题

执行命令

 python install -r .\requirements.txt

出现问题如下：

D:\soft\Python310\python.exe: can't open file 'G:\\Area\\C++\\Fay\\install': [Errno 2] No such file or directory
(.venv) PS G:\Area\C++\Fay> pip install -r .\requirements.txt

解决方案

1. 网上搜了下，换了个清华源，然后还是不行；
2. 又换了一个阿里源，还是不行；
3. 醉了，都重启了

就差换回默认了，还好还清醒，然后发现开了梯子；就把它关了，然后就正常了。

要学会逆向思考啊，全面思考问题，这都耽误了我好几分钟呢!哈哈哈，好了，解决。继续。
