开箱即用的Laravel 4语法错误 [英] Laravel 4 syntax error out-of-the-box

问题描述

我刚刚安装了Laravel 4(Illuminate)，并且在浏览器中打开index.php文件时，遇到了以下错误:

I just installed Laravel 4 (Illuminate) and as I opened the index.php file in a browser, I was met with this error:

解析错误:语法错误，意外的收益"(T_YIELD)，/www/Laravel4/vendor/illuminate/view/src/Illuminate/View/Environment.php中第339行的预期标识符(T_STRING)

Parse error: syntax error, unexpected 'yield' (T_YIELD), expecting identifier (T_STRING) in /www/Laravel4/vendor/illuminate/view/src/Illuminate/View/Environment.php on line 339

我已经修复了meta文件夹的权限，并通过Composer安装了所有依赖项.我正在OSX 10.8.2上运行PHP版本5.5.0alpha2.

I have fixed the permissions for the meta folder, and installed all the dependencies through Composer. I am running PHP version 5.5.0alpha2 on OSX 10.8.2.

推荐答案

这是因为yield成为PHP 5.5中的语言构造(用于

That's because yield became a language construct in PHP 5.5 (used in Generators) - but someone decided that it's a good idea to use this short word to name a function:

public function yield($section)
{
  return isset($this->sections[$section]) ? $this->sections[$section] : '';
}

降级到PHP 5.4(毕竟，它是当前的主流版本，5.5甚至还不是beta版)，并且应该可以正常工作.

Downgrade to PHP 5.4 (after all, it's the current mainstream version, 5.5 is not even in beta yet) and it should work fine.
