ubuntu终端运行python找不到模块_修复Ubuntu16.04 安装python3.6.3 终端terminal无法启动的问题...

ubuntu16.04默认的python版本是2.7, 安装3.6.3后, 出现gnome-terminal无法启动:

修复办法：

1. ctrl+alt+f1 ，输入gnome-terminal，查看无法启动的错误原因

$ gnome-terminal

2. 提示错误信息如下：Traceback (most recent call last):

File "/usr/bin/gnome-terminal", line 9, in

from gi.repository import GLib, Gio

File "/usr/lib/python3/dist-packages/gi/__init__.py", line 42, in

from . import _gi

ImportError: cannot import name '_gi'

3. 查找_gi的库文件$ ls -la /usr/lib/python3/dist-packages/gi/

_gi_cairo.cpython-35m-x86_64-linux-gnu.so

_gi.cpython-35m-x86_64-linux-gnu.so

........

4. 复制一份3.6使用的库文件

$ cd /usr/lib/python3/dist-packages/gi/

$ sudo cp _gi.cpython-35m-x86_64-linux-gnu.so _gi.cpython-36m-x86_64-linux-gnu.so

$ sudo cp _gi_cairo.cpython-35m-x86_64-linux-gnu.so _gi_cairo.cpython-36m-x86_64-linux-gnu.so

5. alt+ctrl+f7返回，重新尝试打开终端，问题解决
