我正在尝试在Heroku上部署Django应用程序。我在requirements.txt上有pycurl == 7.19.5，当我尝试git push heroku master时，我收到错误“推送被拒绝，无法编译Python应用程序”。当我从requirements.txt中删除pycurl时，一切都顺利进行。我可以稍后安装pycurl，但是当我尝试打开我的应用程序时，我收到一个错误“ImportError：没有名为pycurl的模块”即使我可以安装pycurl，它似乎没有正确安装。我的目标是在Heroku上安装pycurl，我是怎么做到的？
尝试“git push heroku master”时出现错误消息，而pycurl位于requirements.txt中：

在Heroku上部署django应用程序时在日志中出现错误消息，而不是在requirements.txt中使用pycurl（但稍后使用pip安装它）并运行带有“heroku open”的应用程序：

我是第一次部署，我已按照Heroku网站上的说明进行了操作（https://devcenter.heroku.com/articles/getting-started-with-django#django-settings）
