命令错误，退出状态为1：python setup.py egg_info检查日志以获取完整的命令输出-通过pip安装auto-py-to-exe时

Question

我尝试在不同于通常通过pip使用的（Windows）设备上下载auto-py-to-exe。但是，运行时出现错误（很长很长很抱歉）：

即使它确实声明我需要Visual Studio C ++ 14.0，我的电脑 也不会安装它 ，以前 也不需要
。我检查了此堆栈溢出问题，但它与另一个pip安装有关，并且没有答案。如果唯一的答案是安装Visual Studio，那么我有点儿困惑。

Answer 1

允许gevent通过发行预发行版本

$ pip install gevent --pre
$ pip install auto-py-to-exe

说明：auto-py-to-exe可以在Windows上的Python 3.8上安装，没有任何问题（可以通过运行进行验证pip install auto-py-to-exe --no-deps）。但是，需要bottle- websocket安装它，而后者又具有gevent依赖性。gevent尚未发布提供可用于Python
3.8的预构建轮子的稳定版本（这将是1.5），因此pip未选择预构建轮子并尝试gevent==1.4从源dist进行构建。安装prerelease
1.5版本gevent可以避免这种情况。
