Question

我有一个require.txt看起来像

# ~/projects/pip-env-test/requirement.txt
Django==2.2

现在我运行了命令pipenv install -r requirements.txt --python 3.6

现在我得到了错误，

[pipenv.exceptions.InstallError]：错误：找不到django == 2.2的匹配发行版

我们知道，Django == 2.2存在，并且--python 3.6命令似乎未使用标志 pipenv 。

完整的错误回溯

  % pipenv install -r requirements.txt --python 3.6                                                                                                                                                          !7968
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

注意：此刻我正在使用pipenv==2020.6.2

Update-1

之后，我尝试运行相同的命令

从virtualenv退出
删除Pipfile和Pipfile.lock

但是，我还有另一个错误，

  % pipenv install -r requirements.txt --python 3.6                                                                                                                                                          !7979

您的日志显示您正在使用Python 2.7，即EOL：

[pipenv.exceptions.InstallError]: DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020.

Django 2.x +完全不支持Python 2（如从日志中所见，适用于Python 2的Django版本为1.1.3，[...]，1.11.27、1.11.28、1.11 .29）。

这就是为什么无法满足Python 2.x上对Django 2.2的要求。
