安装失败

[wuxs231]

报错如下： ERROR: requests 2.22.0 has requirement urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1, but you'll have urllib3 1.25 which is incompatible. Installing collected packages: redis, typed-ast, certifi, uWSGI, marshmallow, marshmallow-sqlalchemy, rope, bcrypt, python-editor, Mako, alembic, Flask-SQLAlchemy, Flask-Migrate, psycopg2, pycodestyle, thriftpy, impyla, PyMySQL, flask-marshmallow, Flask-Script, urllib3, astroid, idna, Flask-Cors, sqlparse, flake8, Jinja2, pylint, boyaa-seed Found existing installation: certifi 2018.4.16 ERROR: Cannot uninstall 'certifi'. 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.

即使加上ignore参数，可以成功安装，但还是无法执行。
