我的英语不好，如果不能很好地提出问题，我感到抱歉。
我在Heroku上部署Django应用时遇到问题。

我执行了git push heroku master命令。

结果如下，

我尝试手动安装（使用以下命令）。

sudo pip install future

结果如下，

  

已经满足要求：/Users/shinya/.pyenv/versions/3.7.5/lib/python3.7/site-packages（0.18.2）中的将来

执行“ git add。git commit”后，错误内容已更改。 错误详细信息如下，

cat runtime.txt 结果如下

python-3.7.3 python-3.7.5

由于在runtime.txt中列出了两个版本，所以我只列出了“ python 3.7.5”，这是“ python -V”的执行结果。

和“冻结点子> requirements.txt” 被执行，“ git push heroku master”被执行。 结果如下。
