当我尝试安装 pyreverse 时,收到以下 pip 消息:
>sudo pip install pyreverse
Collecting pyreverse
Could not find a version that satisfies the requirement pyreverse (from versions: )
Some externally hosted files were ignored as access to them may be unreliable (use --allow-external pyreverse to allow).
No matching distribution found for pyreverse
我不知道如何解决这个问题,希望得到指导。
