Bootsnap 错误 运行 rails 服务，"Could not load the 'mysql' Active Record adapter."
Bootsnap error running rails serve, "Could not load the 'mysql' Active Record adapter."
自从创建了一个不同的 rails 项目后，我的每个项目都遇到了这个 mysql 需求错误。
我尝试使用捆绑器安装 'mysql' 和 'mysql2'（即使我使用的是 postgres）gem。我尝试了不同的 ruby 版本，不同的 rails 版本，不同的 bootsnap 版本，我从 rvm 切换到 rbenv。 None 我的 rails 个项目能够 运行。
bootsnap错误出现如下。
/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:22:in `require': 无法加载 'mysql' Active Record 适配器。确保适配器在 config/database.yml 中拼写正确，并且您已将必要的适配器 gem 添加到 Gemfile。 (加载错误)

尝试更新 ruby 版本并在 Gemefile 中添加 "gem 'mysql2', require: false"
P.S。如果问题仍然存在，请尝试更新捆绑器而不是捆绑安装
您打算使用 pg 还是 mysql2？
无论哪种方式，请检查您是否设置了错误的 ENV['DATABASE_URL']。由于这种情况发生在不同的项目中，我猜你已经在 shell.
中定义了它
Rails 从您的 database.yml 加载访问数据库所需的信息，但也可以从该环境变量中获取该信息。
自从创建了一个不同的 rails 项目后，我的每个项目都遇到了这个 mysql 需求错误。
我尝试使用捆绑器安装 'mysql' 和 'mysql2'（即使我使用的是 postgres）gem。我尝试了不同的 ruby 版本，不同的 rails 版本，不同的 bootsnap 版本，我从 rvm 切换到 rbenv。 None 我的 rails 个项目能够 运行。
bootsnap错误出现如下。 /lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:22:in `require': 无法加载 'mysql' Active Record 适配器。确保适配器在 config/database.yml 中拼写正确，并且您已将必要的适配器 gem 添加到 Gemfile。 (加载错误)

尝试更新 ruby 版本并在 Gemefile 中添加 "gem 'mysql2', require: false"
P.S。如果问题仍然存在，请尝试更新捆绑器而不是捆绑安装
您打算使用 pg 还是 mysql2？
无论哪种方式，请检查您是否设置了错误的 ENV['DATABASE_URL']。由于这种情况发生在不同的项目中，我猜你已经在 shell.
Rails 从您的 database.yml 加载访问数据库所需的信息，但也可以从该环境变量中获取该信息。
