有没有使用 Requests JSON 的简单 Heroku 教程？

当我的 app.py 调用另一个使用 Request 的 json() 的 python 脚本时，Heroku 会引发依赖错误。

Heroku 日志是：

它有问题的代码是这样的：

r = requests.get(link)
myfile = r.json()

这令人困惑，因为它在本地运行良好。

这有一个非常愚蠢的解决方案。我必须在我的 requirements.txt 中导入请求。这就是它无法识别 json() 的原因（因为它是一个请求函数）。

我的 requirements.txt 现在看起来像：

Flask==0.9
Jinja2==2.6
Werkzeug==0.8.3
gunicorn==0.17.2
requests==2.2.1
