Ruby 关于 Rails 4.1.8 Gem::LoadError 对于 mysql2 gem
Ruby on Rails 4.1.8 Gem::LoadError for mysql2 gem
我选择了一个用 Ruby 2.1.3 和 Rails 4.1.8 编写的 4 年前的项目。
很少有 gem 版本化，但我已经按照多个其他线程中的建议通过安装 mysql2 0.3.20 设法在本地获取项目 运行。这样做需要我（在 MacOS 上）用 brew install mysql@57 和 brew install openssl@10.
降级 openssl 和 mysql
然后我可以通过将正确的库传递给它来安装 mysql2：
gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include
一切都在本地工作，一切都很好。
我正在尝试在 Debian 实例上使用 Dokku 部署这个项目。这是从推送到 dokku master 的读数，包括启动 Rails 服务器时抛出的错误：

Post-install message from capistrano:
Capistrano 3.1 has some breaking changes. Please check the CHANGELOG: #Edited for shortened URL
If you're upgrading Capistrano from 2.x, we recommend to read the upgrade guide: # Remove shortened URL
The `deploy:restart` hook for passenger applications is now in a separate gem called capistrano-passenger. Just add it to your Gemfile and require it in your Capfile.
Post-install message from httparty:
When you HTTParty, you must party hard!
Post-install message from twitter-bootstrap-rails:
Important: You may need to add a javascript runtime to your Gemfile in order for bootstrap's LESS files to compile to CSS.

我想我需要弄清楚如何在 debian 实例上使用正确版本的 openSSL 构建 mysql2 gem 但我有点不知所措我会怎么做。 mysql2 gem 安装在本地失败，直到我使用顶部提到的可选参数安装它。 mysql2 gem 版本在 debian 实例上安装正常。任何帮助将不胜感激。
我想我明白发生了什么。在您的 Dockerfile 中，将 DB_URL 从：mysql:// 更改为 mysql2://
您正在加载 mysql2 gem，但向 ActiveRecord 表明您想要通过 mysql gem.
使用连接
我选择了一个用 Ruby 2.1.3 和 Rails 4.1.8 编写的 4 年前的项目。
很少有 gem 版本化，但我已经按照多个其他线程中的建议通过安装 mysql2 0.3.20 设法在本地获取项目 运行。这样做需要我（在 MacOS 上）用 brew install mysql@57 和 brew install openssl@10.
然后我可以通过将正确的库传递给它来安装 mysql2：
gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include
一切都在本地工作，一切都很好。

Post-install message from capistrano:
Capistrano 3.1 has some breaking changes. Please check the CHANGELOG: #Edited for shortened URL
If you're upgrading Capistrano from 2.x, we recommend to read the upgrade guide: # Remove shortened URL
The `deploy:restart` hook for passenger applications is now in a separate gem called capistrano-passenger. Just add it to your Gemfile and require it in your Capfile.
Post-install message from httparty:
When you HTTParty, you must party hard!
Post-install message from twitter-bootstrap-rails:
Important: You may need to add a javascript runtime to your Gemfile in order for bootstrap's LESS files to compile to CSS.

我想我需要弄清楚如何在 debian 实例上使用正确版本的 openSSL 构建 mysql2 gem 但我有点不知所措我会怎么做。 mysql2 gem 安装在本地失败，直到我使用顶部提到的可选参数安装它。 mysql2 gem 版本在 debian 实例上安装正常。任何帮助将不胜感激。
我想我明白发生了什么。在您的 Dockerfile 中，将 DB_URL 从：mysql:// 更改为 mysql2://
您正在加载 mysql2 gem，但向 ActiveRecord 表明您想要通过 mysql gem.
