Heroku deployment failed of missing mariadb-config or MariaDB connector from remote DB-CodePudding

Wanted to make run my Python Flask project via Heroku (it's the first time I am using it). The case is, that I connect to a remote MariaDB on a Ubuntu VM. When I try to push from local git I get an error to be related to the MariaDB. Is there an idea how I can solve this problem?

         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.

CodePudding user response：

It looks like you need the mariadb_config utility at compile time. This is likely because whatever Python driver you are using requires it.

mariadb_config is available in the libmariadb-dev Ubuntu package. You'll need to install that using the Apt buildpack.

Add the buildpack:

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

That buildpack doesn't do dependency resolution, so you'll have to list all transitive dependencies.

Create a new file called Aptfile (no extension) that lists the dependencies you wish to install:
```
mysql-common
mariadb-common
libmariadb3
libmariadb-dev
```
Commit your Aptfile and redeploy.
