在建立一個新的laravel 的專案，一開始就遇到了許許多多的問題，看別人裝都很順利

怎麼自己裝就遇到了一堆的錯誤咧？

xx@xx:/test2$ laravel new blog
Crafting application...
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
                                                                       
  [ErrorException]                                                                         
  "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

又出現了這個錯誤，查了一下資料，說是要更新composer

所以就下了這個指令更新composer

composer self-update

如果更新失敗，請看這一篇
