我在一台新的开发机器上，我在安装Laravel, Spark或任何需要PHP 5.5.30更新的东西时遇到问题。
问题是，我使用的MAMP Pro是运行PHP 7.0.1。我还尝试使用本教程将系统的PHP版本更新为PHP 7: https://coolestguidesontheplanet.com/upgrade-php-on-osx/

我不想通过编辑编辑器文件来绕过所需的PHP版本，因为我不确定它是否会在安装应用程序时引起问题。我的Spark或Laravel安装都不工作，他们只是给出一个500状态错误，这可能是别的东西，但我假设这是同样的问题。
全部修复。感谢kyslik的建议。
我以前尝试过更新我的PATH，但由于某种原因，这次它工作了。我以前一定是弄错了。参考其他人有这个问题，我遵循这个:
