ModuleNotFoundError: No module named 'CommandNotFound'
問題解決如下：
而且，pip install時驼修，還是出現(xiàn)了這個錯誤：
File"/usr/local/lib/python3.6/subprocess.py", line 418,in run output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command'('lsb_release', '-a')'returned non-zeroexitstatus 1.
終端運行l(wèi)sb_release -a則是報錯：
ModuleNotFoundError: Nomodulenamed'lsb_release'
解決方案：
找到lsb_release.py文件和CommandNotFound目錄锭碳，把它們拷貝到報的錯誤中subprocess.py所在文件夾
命令如下：
sudo find / -name'lsb_release.py'
# result:
# /usr/share/pyshared/lsb_release.py
# /usr/lib/python2.7/dist-packages/lsb_release.py
# /usr/lib/python3/dist-packages/lsb_release.py
python -V
# Python 3.6.6
sudo cp? /usr/lib/python3/dist-packages/lsb_release.py /usr/local/lib/python3.6/
