ubuntu 中pip 安装软件报错：“Command 'lsb_release -a' returned non-zero exit status 1.”

ModuleNotFoundError: No module named 'CommandNotFound'

问题解决如下：

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-zeroexitstatus 1.

终端运行lsb_release -a则是报错：

ModuleNotFoundError: Nomodulenamed'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/
