我在苹果电脑上

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

您标记了这个问题3.x，但getch安装的证据清楚地表明它已安装在site-packages中，为2.7。您还为pip提供了一个指向Python2tarball的显式路径。

为Python的一个版本安装包并不会安装其他版本的包。运行pip3来安装Python3的软件包(根据安装程序的不同，它可能被命名为pip-3.5等)。如果没有安装pip3，python3 -mensurepip应该添加它(取决于Python次要版本)，否则您必须手动安装它。无论哪种方式，一旦您拥有了pip3，您只需要正确地安装该软件包：

sudo pip3 install getch
