我正在使用Mac,所以无法使用msvcrt.

谢谢您的帮助.

解决方法

安装失败,因为它正在寻找python3标头.查看 https://pypi.python.org/pypi/getch,列出了两个源分发,getch-1.0-python2.tar.gz和getch-1.0.tar.gz.

对于python 2,你需要前者,但看起来后者正在被选中(同样的事情发生在我身上).我不确定pip是否应该知道如何选择正确的pip,但你可以手动选择：

复制链接,

pip install https://pypi.python.org/packages/source/g/getch/getch-1.0-python2.tar.gz#md5=586ea0f1f16aa094ff6a30736ba03c50

适合我
