Question

我已经在谷歌上搜索了几天了。由于依赖关系，我无法将Laravel项目从5.7更新到5.8。当我在composer.json中更新依赖包版本值并尝试执行laravel更新时，它会忽略我的更新，并实际上将其还原为原始值。

Composer.json

}

我采取的步骤：

1）编辑我的composer.json文件，更改为：“ laravel / framework”：“ 5.7。”
到：“ laravel / framework”：“ 5.8。”

2）运行作曲家更新

输出：

Package egeloen/http-adapter is abandoned, you should avoid using it. Use php-http/httplug instead.

结果：

composer.json文件已重置为显示：“ laravel / framework”：“ 5.7。*”

我尝试过的事情： 1）尝试执行此操作之前，请删除composer.lock文件。 2）执行php artisan缓存：在我进行更新之前请先清除。

必须有一个经历过这些问题的人可以帮助我。

Answer 1

只需遵循Official Upgrade Guide：

将您的composer.json laravel/framework更新为5.8.*
运行composer update。无需删除`composer.lock
查看上面的升级指南，了解可能会影响您的应用程序的更改。此版本几乎没有重大更改。

Answer 2

结果表明，IDE（Eclipse Neon）从未更新过我的composer.json文件，即使它表明我正在这样做。我从命令行对其进行了编辑，并且可以正常工作。

Answer 3

我在这种情况下的亲身经历使我学会了使用新版本的Laravel创建一个全新的项目，然后添加我的个人更改（即控制器，模型，迁移，视图，配置等）。当然，使用单元测试将极大地帮助您成功地将项目升级到下一个级别。

顺便说一句。 this link可以帮助您安全地进行升级，但是我再次强烈建议您使用全新的安装方式，而不要处理任何更改。
