Heroku部署失败，因为缺少远程DB中的mariadb-config或MariaDB连接器

Question

想通过Heroku运行我的Python项目(这是我第一次使用它)。情况是，我连接到Ubuntu上的远程MariaDB。当我试图从本地git推送时，我会得到一个与MariaDB相关的错误。有什么办法解决这个问题吗？

×python setup.py egg_info没有成功运行。

         This error typically indicates that MariaDB Connector/C, a dependency which must be preinstalled,

         is not found.

         If MariaDB Connector/C is not installed, see installation instructions

         at: https://github.com/mariadb-corporation/mariadb-connector-c/wiki/install.md.

         If MariaDB Connector/C is installed, either set the environment variable MARIADB_CONFIG or edit

         the configuration file 'site.cfg' to set the 'mariadb_config' option to the file location of the

         mariadb_config utility.

看起来您需要编译时的mariadb_config实用程序。这很可能是因为您所使用的Python驱动程序都需要它。

mariadb_config Ubuntu软件包.您需要使用Apt构建包来安装它。

1. 添加buildpack： heroku构建包:add 1 heroku社区/apt
2. 该buildpack不执行依赖关系解析，因此您必须列出所有传递依赖项。 创建一个名为Aptfile (无扩展名)的新文件，列出希望安装的依赖项： mysql-通用mariadb-通用libmariadb3 libmariadb dev
3. 提交您的Aptfile并重新部署。
