自己在ubuntu中安装python3.6后常见错误及解决，因为 stackoverflow 上回答较多，有时也不知道看哪一个，所以我将其总结收集起来，原回答在参考中已附：
1. 问题1: No module named “apt_pkg”:
解决方案：卸载后重装 python-apt，再把apt_pkg 的 py3.5 版 复制为 py3.6。参考: stackoverflow: python-dev installation error: ImportError: No module named apt_pkg
sudo apt-get remove --purge python-apt
sudo apt-get install python-apt -f
# sudo find / -name "apt_pkg.cpython-35m-x86_64-linux-gnu.so" # locate ".so", in generally, location is "/usr/lib/python3/dist-packages/"
cd /usr/lib/python3/dist-packages/
sudo cp apt_pkg.cpython-35m-x86_64-linux-gnu.so apt_pkg.cpython-36m-x86_64-linux-gnu.so
2. 问题2: No module named “pip._internal”:
解决方案：重装 pip 即可，(参考: github/pypa/pip: ModuleNotFoundError: No module named ‘pip._internal’)
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
sudo python get-pip.py
3. 问题3: ImportError: cannot import name main:
更新 pip 时可能的错误。解决方案( 参考: stackoverflow: Error after upgrading pip: cannot import name ‘main’)：
修改 pip 文件内容：
sudo vim /usr/bin/pip
将
from pip import main
if __name__ == '__main__':
sys.exit(main())
替换为
from pip import __main__
if __name__ == '__main__':
sys.exit(__main__._main())
Hello this is kind of of off topic but I was wanting to know if blogs use WYSIWYG
editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding expertise so
I wanted to get advice from someone with experience.
Any help would be enormously appreciated!
Here you can ask anything, I’ll answer whatever I know.
If you don’t have coding expertise, then I recommend you learn a little bit markdown, it is a simple lightweight markup language.
I’m using WP Editor.md to write my blog, this editor will auto parse md to html.
Wow, this paragraph is fastidious, my younger sister is analyzing
these things, therefore I am going to inform her.
Thanks.
