安装 pip 包 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。在那之后，我一直在尝试安装 auto-py-to-exe。每当我在命令提示符下键入pip install auto-py-to-exe 时，就会出现此输出

我认为 Microsoft Visual C++ 有问题，正如我在错误中看到的那样 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，我看到了这个窗口 error in installing Microsoft Visual C++ 14.0 (picture)

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program list (picture)。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，我发现了问题所在。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wheel文件。和之前一样在 wheel 文件的目录中打开命令提示符并再次输入pip install (filename)。 在所有这些之后，输入pip install auto-py-to-exe

希望这对你有用，对我有用！
