版本冲突：（pip 9.0.2（/usr/local/lib/python3.5/site-packages），Requirement.parse（'pip==9.0.1'）

Question

我使用 docker 命令docker-compose build和docker-compose up -d

yum install python-35 -y并安装软件包，然后添加pip-3.5 install --upgrade pip到 docker-compose.yml 中，它会引发 VersionConflict 错误

You are using pip version 9.0.2, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
+ pip-3.5 install awscli

raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.VersionConflict: (pip 9.0.2 (/usr/local/lib/python3.5/site-packages), Requirement.parse('pip==9.0.1'))

During handling of the above exception, another exception occurred:

但我不知道为什么它需要 pip==9.0.1 对我来说......

我如何使用 pip>=9.0.2 解决问题？

添加

我的设置.py

install_requires = [
    'nitro>=1.3.0,<1.4.0',
    'mysqlclient',
    'requests',
    'beautifulsoup4',
    'google-api-python-client',
    'httplib2',
    'raven',
]

当我在 github 上检查aws-cli/setup.py时

和aws-cli/requirement.txt

没有pip=9.0.1

当我改变时pip-3.5 install awscli->pip-3.5 install ipython

它有同样的错误

+ pip-3.5 install ipython

Answer 1

通过 python 调用 pip 对我来说很有效，例如：

python3 -m pip install --upgrade pip==9.0.1

（或您在 中看到的任何版本Requirement.parse('pip==X.Y.Z')）
