python pip install出现问题

1、pip install时，还是出现了这个错误：
subprocess.CalledProcessError: Command'('lsb_release', '-a')'returned non-zeroexitstatus

解决方法：
找到lsb_release.py文件，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/local/python3.6/lsb_release.py
/usr/share/pyshared/lsb_release.py
/usr/lib/python3/dist-packages/lsb_release.py
/usr/lib/python2.7/dist-packages/lsb_release.py

sudo find /usr -name python3.6

# result
/usr/local/python3.6
/usr/local/python3.6/bin/python3.6
/usr/local/python3.6/lib/python3.6

sudo cp /usr/lib/python3/dist-packages/lsb_release.py /usr/local/python3.6/lib/python3.6/
