我正在尝试在 heroku dyno 上安装 Sharetribe 的实例。我正试图创建数据库。我首先尝试了 rake db:migrate，它适用于大多数迁移，但其中一个失败了。

有人建议我使用 rake db:structure:load，所以我尝试了，但 Heroku 收到一个错误，提示需要将 mysql 添加到 PATH 变量中。为什么会这样，我该如何解决？我不确定为什么它会发生在 db:schema:load 和 db:structure:load 上，但不会发生在 db:migrate 上。

带有错误消息的完整堆栈跟踪是：

rake aborted!
failed to execute:
mysqlPlease check the output above for any errors and make sure that `mysql` is installed in your PATH and has proper permissions.

如果您需要运行heroku run bundle exec rake db:structure:load而不是安装mysql客户端。要安装其他软件包，您需要添加Buildpacks（基于官方或社区）。

对于 mysql，我成功使用了https://github.com/din-co/heroku-buildpack-mysql

heroku buildpacks:add --index 1 https://github.com/din-co/heroku-buildpack-mysql
git commit --amend --allow-empty --no-edit
git push heroku -f

Heroku 不支持mysql，您需要pg在生产块的 gemfile 中使用 gem。请阅读Heroku 上的 Rails 5.x 入门
