Question

我正在尝试使用AWS Elastic Beanstalk部署Flask应用程序，但遗憾的是遇到了以下错误。让我感到困惑的是，我的虚拟环境和本地机器中当前版本的pip是9.0.1，所以我不确定它为什么会拿起7.1.2。

Command "/opt/python/run/venv/bin/python2.7 -c "import setuptools, tokenize;__file__='/tmp/pip-build-L32BGc/cffi/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-nO55i_-record/install-record.txt --single-version-externally-managed --compile --install-headers /opt/python/run/venv/include/site/python2.7/cffi" failed with error code 1 in /tmp/pip-build-L32BGc/cffi
  You are using pip version 7.1.2, however version 9.0.1 is available.
  You should consider upgrading via the 'pip install --upgrade pip' command.

这是因为pip版本太旧了。您可以添加.ebextensions来解决此问题。

在应用的根文件夹中添加.ebextensions文件夹
在其中放入pip.config文件，内容为：


commands:
  update_pip:
  command: "/opt/python/run/venv/bin/pip install --upgrade pip"

再次运行eb deploy，它将被解析。
