无法通过brew services启动mongodb-community服务求助

问题描述 #

执行brew services start mongodb-community时触发以下错误：

Error: undefined method `plist_startup' for #<Formula mongodb-community (stable) /opt/homebrew/Library/Taps/mongodb/homebrew-brew/Formula/mongodb-community.rb>
Did you mean?  plist_name
/opt/homebrew/Library/Taps/homebrew/homebrew-services/lib/service/formula_wrapper.rb:71:in `service_startup?'
/opt/homebrew/Library/Taps/homebrew/homebrew-services/lib/service/services_cli.rb:280:in `service_load'
/opt/homebrew/Library/Taps/homebrew/homebrew-services/lib/service/services_cli.rb:122:in `block in start'
/opt/homebrew/Library/Taps/homebrew/homebrew-services/lib/service/services_cli.rb:97:in `each'
/opt/homebrew/Library/Taps/homebrew/homebrew-services/lib/service/services_cli.rb:97:in `start'
/opt/homebrew/Library/Taps/homebrew/homebrew-services/lib/service/commands/start.rb:12:in `run'
/opt/homebrew/Library/Taps/homebrew/homebrew-services/cmd/services.rb:130:in `services'
/opt/homebrew/Library/Homebrew/brew.rb:86:in `<main>'

重新安装Homebrew和MongoDB后，仅重启电脑后能正常运行一次，再次启动仍出现相同错误。

解决方案 #

方案1：修改homebrew-services的代码文件（快速修复） #

错误源于homebrew-services调用了MongoDB formula未实现的plist_startup方法，将其替换为存在的plist_name即可：

1. 打开报错的文件：

   open /opt/homebrew/Library/Taps/homebrew/homebrew-services/lib/service/formula_wrapper.rb
   

2. 找到第71行附近的service_startup?方法，原代码类似：

   def service_startup?
     @formula.plist_startup.present?
   end
   

3. 将@formula.plist_startup替换为@formula.plist_name，修改后：

   def service_startup?
     @formula.plist_name.present?
   end
   

4. 保存文件后，重新启动MongoDB服务：

   brew services start mongodb-community
   

方案2：绕过brew services，手动启动MongoDB #

如果不想修改工具代码，可直接使用mongod命令启动：

• 停止残留服务：

  brew services stop mongodb-community
  

• 通过配置文件启动MongoDB（后台运行）：

  mongod --config /opt/homebrew/etc/mongod.conf --fork
  

• 设置开机自启：将上述启动命令添加到你的shell配置文件（如~/.zshrc或~/.bashrc），或通过系统偏好设置→用户与群组→登录项添加该命令的执行脚本。

方案3：重置brew服务关联并重装MongoDB #

1. 清理无效的服务关联：

   brew services cleanup
   

2. 卸载MongoDB：

   brew uninstall mongodb-community
   

3. 修复并更新MongoDB的tap仓库：

   brew tap --repair mongodb/homebrew-brew
   brew update
   

4. 重新安装MongoDB：

   brew install mongodb-community
   

5. 启动服务：

   brew services start mongodb-community
