如题，错误提示如下：

错误信息提示找不到lsb\_release模块，原因是系统自带的Python版本是3.5，新装的Python3.7没有完整安装

解决方法是设置python3.7的系统模块加载位置，或把位于python3.5路径中的系统模块拷贝到3.7中。我采用的是简单粗暴的第二种方法，具体步骤如下：

python3.5 -c 'import lsb_release;print(lsb_release.__file__)'  # 找到lsb_release.py所在路径
    # /usr/lib/python3.5/dist-packages/lsb_release.py
    python3.7 -c 'import sys;print(sys.path)'  # 打印3.7的系统加载路径
    # [... '/home/ubuntu/.local/lib/python3.7/site-packages', '/usr/local/lib/python3.7/dist-packages']
    sudo cp /usr/lib/python3.5/dist-packages/lsb_release.py /usr/lib/python3.7/dist-packages/  # 复制3.5版的文件到3.7的某一个加载路径里
    python3.7 -c 'import lsb_release;print(lsb_release.__file__)'  # 校验是否复制成功
