composer install报错

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.

Problem 1
- The requested package overtrue/laravel-lang 3.0.14 is satisfiable by overtrue/laravel-lang[3.0.14] but these conflict with your requirements or minimum-stability.

 

以上是报错内容

解决方案:

删掉composer.lock文件中对应的错的地方,或者修改低级别的版本

再次执行composer install
