Composer在新宅基地上出现kylekatarnls / update-helper失败

Question

我已经在新计算机上安装了宅基。我已经提取了我的代码（该代码可在其他计算机以及服务器上运行）。我的项目是在Laravel 5.7中完成的

当我执行作曲家要求将所有内容准备就绪时，出现此错误：插件kylekatarnls / update-helper无法初始化，找不到类

我尝试过作曲家clear：cache，重新安装了homestead-7盒子。没有它起作用。我仍然遇到相同的错误

但是无论我得到同样的错误

Answer 1

我试过

composer global require kylekatarnls/update-helper

然后它起作用了

Answer 2

我假设最新的 laravel / homestead 盒子与 laravel 5.7.* 不兼容。在 homestead/script/homestead.rb 中，我将第 21 行更改为： config.vm.box_version = settings['version'] ||= '= 7.1.0'

因此我强迫我的家园只使用box v.7.1.0（就像在我的另一台计算机上一样）。

vagrant up
vagrant ssh
composer require 

就像魅力一样。
