python - 我无法安装 install firebase-admin

问题描述

我有以下错误：

MacBook-Air:Firebase takeyuki$ python -m pip install --upgrade firebase-admin
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

... some lines are omitted ...

Installing collected packages: futures, googleapis-common-protos, grpcio, google-api-core, uritemplate, httplib2, google-auth-httplib2, google-api-python-client, google-cloud-core, google-resumable-media, google-cloud-storage, google-cloud-firestore, msgpack, cachecontrol, firebase-admin
  Found existing installation: futures 3.0.3
Cannot uninstall 'futures'. 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.

此消息提到期货模块似乎不属于 pip，但

MacBook-Air:Firebase takeyuki$ python -m pip list | grep futures
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.
futures                            3.0.3

那么，我该如何解决呢？谢谢你的建议！

解决方案

您可以尝试以下步骤吗？

pip install --upgrade --force-reinstall pip==20.0.0
pip install futures --disable-pip-version-check
pip install --upgrade pip

另一种选择是在 virtualenv 中工作：

pip install virtualenv
virtualenv -p python venv
source venv/bin/activate
python pip install firebase-admin

更新：确实有效的选项：

pip install --ignore-installed futures
