pip 安装 getch Python3.5 时出错

Question

我正在运行ning Fedora 24。我想在 Python 3.5.2 上导入 getch 模块（我认为它已经安装了，但是当我运行 python -V，上面写着 Python 2.7.11)

当我输入 pip install getch 时，我得到了这个：

最后一行是红色的。

那么，我怎样才能让它发挥作用？

谢谢

更新：好的，所以我设法将 pip 更新到最新版本，但现在我遇到了下一个问题（似乎是一个进步）：

Answer 1

好的，我就是这样解决的：

sudo dnf install python3-devel

而不是：

sudo dnf install python-devel

经过几个小时的研究，现在看起来很傻。

谢谢

Answer 2

我正在使用 Ubuntu，我用同样的 issue.I 修复了它：

pip install py-getch

Answer 3

试试这个

pip install --user py-getch
