python - 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 Commit docker-compose build 和 docker-compose up -d

yum install python-35 -y 并安装软件包，我在 docker-compose.yml 中添加 pip-3.5 install --upgrade pip 它引发了 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
Traceback (most recent call last):

needed = self.resolve(parse_requirements(requirements))
  File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 875, in resolve
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......

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',
]

当我检查aws-cli/setup.py时在github上

和aws-cli/requirement.txt

没有pip=9.0.1

当我更改pip-3.5安装awscli -> pip-3.5安装ipython

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

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