Python 未导入 GETCH

Question

我已经安装了（通过 PIP/The 终端）GETCH，但是 python 在我告诉它时无法识别它

import getch

我在 Mac

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

Answer 1

您标记了这个问题 3.x，但您安装 getch 的证据清楚地表明它已安装在 2.7 的 site-packages 中。您还提供了 pip 到 Python 2 tarball 的显式路径。

为 Python 的一个版本安装软件包不会为其他版本安装它。运行 pip3 为 Python 3 安装软件包（它可能被命名为 pip-3.5 或类似名称，具体取决于设置）。如果 pip3 没有安装，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 pip3，您只需要正确安装软件包：

sudo pip3 install getch
