Question

当我尝试安装用于将项目（学习日志）部署到Heroku所需的软件包时，它一直提示我此错误：

Josephs-MacBook-Pro:learning_log joseph$ source ll_env/bin/activate

(ll_env) Josephs-MacBook-Pro:learning_log joseph$ pip install psycopg2==2.7.*

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. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

我不知道为什么我下载python 2.7并一直使用它时一直说python3。

另外，当我昨天尝试运行服务器以获取学习日志时，它将无法正常运行（之前运行良好）。最终，我（在环境中）重新下载了python3 bootstrap4和django并运行服务器。旁注：我必须在python3 mangage.py runserver的末尾键入3才能正常工作。

有什么想法解决此问题并将其部署到Heroku中吗？
