Laravel PackageManifest.php 第 131 行:未定义索引:名称

Laravel PackageManifest.php line 131: Undefined index: name(Laravel PackageManifest.php 第 131 行:未定义索引:名称)

问题描述

我用这个命令更新了作曲家:

I updated the composer with this command:

composer self-update

已更新至 2.0.4 版.然后当我尝试使用以下命令启动我的 Laravel 项目时:

It was updated to version 2.0.4. Then when I tried to launch my Laravel project using:

php artisan serve

我收到了这个错误:

In PackageManifest.php line 131:

 Undefined index: name

我尝试通过以下方式恢复作曲家的旧版本:

I tried getting back to the old version of the composer with this:

composer self-update --rollback

composer 已降级到 1.9.3 版，但对错误没有帮助.然后我用这个命令再次更新作曲家:

The composer was downgraded to version 1.9.3, but it didn't help with the error. Then I used this command to update the composer again:

composer self-update --stable

仍然出现同样的错误.

这是 PackageManifest.php 文件的第 131 行:

This is the line 131 of the PackageManifest.php file:

return [$this->format($package['name']) => $package['extra']['laravel'] ?? []];

推荐答案

首先，使用composer self-update后要再次检查版本.然后，您尝试 composer update.最后，运行 php artisan serve.

First, you should check again version after using composer self-update. Then, you try composer update. Finally, you run php artisan serve.
