在旧版本上成功使用多年后尝试升级 Laravel 并升级到 OSX 10.15.2 (Catalina) 之后，我似乎无法再为 cli 安装 Laravel。

Installation failed, reverting ./composer.json to its original content.

我在这里和其他地方花了 2 天时间研究建议，但没有成功解决此问题。非常感谢任何建议。

【参考方案1】：

您的 /Users/$username/.composer/composer.lock 文件中似乎有不兼容的硬编码依赖项

我也遇到过这个问题，原来我的 laravel/homestead 和 laravel/valet 使用的是旧版本的 symfony/console。

简单修复：

1. composer global remove laravel/homestead
2. composer global remove laravel/valet
3. Finally, composer global install laravel/installer

【参考方案2】：

经过一系列的随机尝试，我终于可以跑了：

composer global update

然后

composer global require laravel/installer

这似乎解决了问题。

【讨论】：

我遇到了同样的问题，但使用 guzzlehttp/guzzle。它也解决了它。
