一、解决方案

1、首先更新pip后看是否能够运行。

python -m pip install --upgrade pip

2、如果不能则尝试（谨慎操作'ProxyServer'请先备份）：

1. Press Win+R to open Run, type in “regedit” and click OK.
2. Move to HKEY_CURRENT_USER/Software/Microsoft/Windows/Current Version/Internet Settings.
3. Find a file with the name 'ProxyServer' and delete it.
4. Open cmd
5. Fire a command 'pip install flask-bcrypt'
