pdftotext library是requirements.txt中的一个要求。尝试推送到 heroku 时,出现以下错误:

通常我会通过安装 libpoppler-cpp-dev
来解决这个问题 apt
.但是在 heroku 上,我没有 root 访问权限来执行此操作。有解决方案吗?
我意识到严格来说,这不是一个编程问题。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原谅我。
来自 如何安装应用程序所需的其他软件包?
我们不为安装额外的软件包提供官方支持,但有几个不受支持的选项。
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 包来使用它。然后,当您部署应用程序时,构建包将在测功机上安装这些软件包。
因此,为此,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。让我知道这是否有帮助!
