线上服务器，更新镜像源，composer.lock 文件生成错误。

composer.json 贴一下

把 composer.lock 删掉，然后再 install

@Epona 你删掉 lock，再 install，会安装最新的包，在生产环境这样，可能会搞出事来，，

composer update nothing 直接这样，就可以只更新 lock 文件里的源，，，

之前在论坛看到的~~

@largezhou 如果 composer.json 里面版本指定没问题的话，一般倒是没啥问题，你这个也是一个不错的解决办法

composer update nothing，学习了。

上次看到说 composer.lock 也要保存到 .gitignore 才对，被我删了，我赶紧恢复下。 :joy:

@陈伯乐 这是我的composer.json

@Epona 其实这种我也试过了。删除composer.lock，
执行
composer install -vvv
查看详情是从阿里云镜像下载的。 下载完毕以后，从新生成的composer.lock文件中还是laravel-china的镜像地址
