Composer在将laravel更新到5.6时坚持‘有些东西改变了，再次查看所有规则’

Question

我正在尝试更新我的Laravel应用程序。我以前是5.2岁，现在是5.5岁。在这里之前一切都很好。

现在，我已经在我的编写器文件中将其更改为5.6.*，并且无论我运行多少次composer update，它都停留在

Something's changed, looking at all rules again (pass #142)

不管我让它传了多少次。

最初，第三方软件包https://github.com/spatie/laravel-backup有一个问题，这是导致问题的原因，但我也尝试删除它。还是同样的问题。:(

Answer 1

我试着一次删除依赖并更新

"laravel/cashier": "~6.0"

这是导致问题的原因。将其更改为~7.0，现在它工作得很好。

任何其他有这个问题的人，只要试着移除所有依赖项，并尝试一次安装一个，你很可能会找到罪魁祸首，然后你可以尝试单独更新那个。

Answer 2

对我来说，罪魁祸首是phpspec/phpspec，它似乎是从Laravel 5.2开始的no longer needed。

Answer 3

如果你安装了这个扩展"nesbot/carbon"："^2.17"，只需升级他即可。
