我使用的是 Mac，所以无法使用 msvcrt。
感谢您的帮助。
最佳答案
安装失败，因为它正在寻找 python3 header 。看着https://pypi.python.org/pypi/getch列出了两个源分发版，getch-1.0-python2.tar.gz 和 getch-1.0.tar.gz。
对于 python 2，您需要前者，但看起来正在选择后者(同样的事情发生在我身上)。我不确定 pip 是否/如何知道如何选择正确的，但您可以手动选择:
复制链接，
pip install https://pypi.python.org/packages/source/g/getch/getch-1.0-python2.tar.gz#md5=586ea0f1f16aa094ff6a30736ba03c50
