安装 pip package auto-py-to-exe 时出错

Question

我正在尝试安装 auto-py-to-exe。 事实上，我安装了它，但几个月前，我重新安装了我的 windows 10。之后，我不断尝试安装 auto-py-to-exe。 每当我在命令提示符下输入pip install auto-py-to-exe时，这个 output 就会出现

我认为 Microsoft Visual C++ 有问题，正如我在错误error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/ error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

但是当我尝试安装 Microsoft Visual C++ 时，我在安装 Microsoft Visual C++ 14.0 时看到这个 window 错误（图片）

我再次检查了程序列表，我有点困惑应该卸载哪个，应该保留哪个程序列表（图片） 。 总的来说，我在这个问题上停留了三个多星期，如果有人能解决这个问题，我将不胜感激。

Answer 1

最后，我弄清楚了问题所在。 首先，我必须从https://www.lfd.uci.edu/~gohlke/pythonlibs/#greenlet安装一个合适的 greenlet 轮文件。 然后在wheel文件的目录下打开命令提示符。 然后输入pip install (filename)之后，再次从https://www.lfd.uci.edu/~gohlke/pythonlibs/#gevent下载 gevent 的轮子文件。 和之前一样，在 wheel 文件目录中打开命令提示符并再次键入pip install (filename) 。 毕竟，输入pip install auto-py-to-exe

希望这对你有用，因为它对我有用！
