pdftotext库是requirements.txt中的要求。尝试推送到heroku时，出现以下错误：

通常我可以通过将libpoppler-cpp-dev与apt安装来解决此问题。但是在heroku上，我没有root访问权限。有解决方案吗？

我意识到严格来说，这不是编程问题。但是我需要这个来部署我的程序，所以我希望这里的纯粹主义者能原谅我。

来自How do I install additional software packages that my application requires?：

我们不提供安装额外软件包的官方支持，但有两个不受支持的选项。

一个是实验性的heroku-apt-buildpack。您可以通过在应用程序的Aptfile中包含任何APT软件包来使用它。然后，在部署应用程序时，buildpack会将这些软件包安装在dyno上。

因此，要执行此操作，请首先添加构建包：

heroku buildpacks:add --index 1 heroku-community/apt

然后，在源目录中创建一个包含以下内容的Aptfile：

libpoppler-cpp-dev

并像往常一样部署。让我知道是否有帮助！
