删除作曲家中的学说/学说移民 - 所有工作

 - Removing doctrine/doctrine-migrations-bundle (v1.2.0)
 - Removing doctrine/migrations (1.4.1)
 - Removing ocramius/proxy-manager (2.0.4)
 - Removing zendframework/zend-code (3.1.0)
 - Removing zendframework/zend-eventmanager (3.0.1)
 - Removing ocramius/package-versions (1.1.1)

我的版本PHP（5.6.28-1）没有迁移捆绑一切正常如何解决此问题？

Answer 1

否，我尝试了许多版本捆绑包，但是在将PHP版本更改为7.0

Answer 2

我认为某处有一个特殊的符号。尝试删除最后一行（不要忘记在上一行上删除逗号）并致电命令composer require doctrine/doctrine-migrations-bundle。

它将在composer.json中添加正确的行。
