ModuleNotFoundError: No module named 'CommandNotFound'

错误来源：

Ubuntu18系统，安装最新版python后就出现如下错误：

ModuleNotFoundError: No module named ‘CommandNotFound’

而且，pip install时，还是出现了这个错误：

File “/usr/local/lib/python3.6/subprocess.py”, line 418, in run
output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command ‘(‘lsb_release’, ‘-a’)’ returned non-zero exit status 1.

终端运行lsb_release -a则是报错：

ModuleNotFoundError: No module named ‘lsb_release’

---

解决方案：

找到lsb_release.py文件和CommandNotFound目录，把它们拷贝到报的错误中subprocess.py所在文件夹

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/

注意：如果是使用的anaconda，则需要拷贝至anaconda/lib/python3.6/这个目录才有用
