为pdftotext生成控制盘时，命令“gcc”失败，退出状态为1

Question

我正在使用Python 3.7.0、Django 3.0.4，并尝试在Heroku中托管。我使用的是windows操作系统，我找到的解决方案最多的是Linux。每次我试着进入Heroku的大师，都会发生以下错误。谁能帮我一下吗

如果您要部署到Heroku，您可能要部署到Ubuntu Linux（版本16或18，取决于您选择的版本）：

https://devcenter.heroku.com/articles/stack

我不使用Heroku，但看起来您缺少必要的开发库。您需要安装libpoppler-cpp-dev。如果你有自己的Ubuntu安装，你会这样做：

apt-get install libpoppler-cpp-dev

但是，我相信您需要使用它通过Heroku上的apt安装：https://github.com/heroku/heroku-buildpack-apt

祝你好运
