我正在使用Python 3.7.0，Django 3.0.4，并试图在Heroku中托管。我正在使用Windows OS，而我发现的最多解决方案是在Linux上。每次我尝试推入Heroku的母版时，都会发生以下错误。有人可以帮我吗？

如果要部署到Heroku，则可能要部署到Ubuntu Linux（版本16或18，具体取决于所选内容）：

我不使用Heroku，但这看起来好像您缺少必要的开发库。您需要安装libpoppler-cpp-dev。如果您有自己的Ubuntu安装，则将执行以下操作：
apt-get install libpoppler-cpp-dev
但是，我相信您需要使用它通过apt在Heroku：https://github.com/heroku/heroku-buildpack-apt
祝你好运！
