错误没有这样的文件或目录：将应用程序推送到heroku时出现'gdal-config'

Question

我尝试将包含 geopandas 的应用推送到 heroku，但出现此错误：

我在this heroku 帖子中看到您应该添加heroku 的地理构建包。但是如果我这样做了，就像我的应用 requirements.txt 不再安装一样。

这是我在添加 heroku 的地理构建包并删除 BUILD_WITH_GEO_LIBRARIES 后得到的结果，就像帖子说的那样：

他不再安装 pip 要求。谁能帮我解决这个问题？

根据您的标签，我假设您使用的是 python。如果是这样，你错过了 python buildpack。在你的 gitbash 或 cmd 上执行：

heroku buildpacks:set heroku/python
