报错处理1：
File "packaging/release/versionhelper/version_helper.py", line 9, in <module> from packaging.version import Version, VERSION_PATTERN
处理方法：
pip install packaging
报错处理2：
Cannot uninstall 'pyparsing'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
处理方法：
pip install packaging --ignore-install
