在命令行上运行 Artisan (Laravel) 时出现致命错误

Fatal Error While Running Artisan (Laravel) on Command Line

提问by Graham Kennedy

I am experiencing a fatal error while using artisan on the (fantastic) Laravel PHP framework.

我在（很棒的）Laravel PHP 框架上使用 artisan 时遇到了致命错误。

I recently downloaded v3.2.1 of Laravel, and I tried running the following command line from within the directory that artisan resides:

我最近下载了 Laravel 的 v3.2.1，并尝试从 artisan 所在的目录中运行以下命令行：

php artisan key:generate

This should create a random key for me in my applications/application.php file. (Please see http://laravel.com/docs/artisan/commandsfor a specific reference to this command.)

这应该在我的 applications/application.php 文件中为我创建一个随机密钥。（有关此命令的具体参考，请参阅http://laravel.com/docs/artisan/commands。）

However, when I run this command from the shell I receive the following error:

但是，当我从 shell 运行此命令时，我收到以下错误：

Warning: chdir(): No such file or directory (errno 2) in /home/[USERNAME REMOVED]/websites/[DIRECTORY REMOVED]/htdocs/dev/sb4/paths.php on line 62                                                                                                       

Parse error: syntax error, unexpected T_STRING in /home/[USERNAME REMOVED]/websites/[DIRECTORY REMOVED]/htdocs/dev/sb4/laravel/core.php on line 1  

This is what's on line 62 of paths.php:

这是paths.php第62行的内容：

chdir(__DIR__);

This is what's on line 1 of core.php:

这是 core.php 第 1 行的内容：

<?php namespace Laravel;

My question is this: Are there any specific environment, directory, or other permissions that I should modify to get artisan up and running.

我的问题是：是否有任何特定的环境、目录或其他权限我应该修改以启动和运行 artisan。

A little background:

一点背景：

• I installed Laravel 3.2.1 yesterday for the first time
• I can run a simple web application successfully on my system (i.e. I can route a request to a controller and load up the associated blade properly)
• I simply downloaded the Laravel 3.2.1 (laravel-laravel-v3.2.1-8-gaae8b62.zip) from GitHub and extracted it on my server

• 我昨天第一次安装了 Laravel 3.2.1
• 我可以在我的系统上成功运行一个简单的 Web 应用程序（即我可以将请求路由到控制器并正确加载相关的刀片）
• 我只是从 GitHub 下载了 Laravel 3.2.1 (laravel-laravel-v3.2.1-8-gaae8b62.zip) 并将其解压缩到我的服务器上

My environment:

我的环境：

• PHP 5.3.13 on a shared host at Dreamhost
• FireSSH to run the commands

• Dreamhost 共享主机上的 PHP 5.3.13
• FireSSH 来运行命令

My root directory: (permissions in parenthesis)

我的根目录：（括号内为权限）

• /application (775)
• /bundles (775)
• /laravel (775)
• /public (775)
• /storage (775)
• /artisan (664)
• /paths.php (777)

• /申请 (775)
• /捆绑 (775)
• /laravel (775)
• /公共 (775)
• / 存储 (775)
• /工匠 (664)
• /paths.php (777)

Please let me know if there are any other details about my setup that relevant. I'm really not sure what will help in troubleshooting this issue.

请让我知道是否有任何其他有关我的设置的详细信息。我真的不确定什么有助于解决这个问题。

First off, thanks @KingCrunch, your first response led me down the correct path toward resolving this issue. Additionally, I received an excellent response from Dreamhost technical support (specifically Gary S), who gave me the concise answer I was looking for.

首先，感谢@KingCrunch，您的第一个回复让我走上了解决这个问题的正确道路。此外，我收到了 Dreamhost 技术支持（特别是 Gary S）的出色回复，他给了我我正在寻找的简洁答案。

The issue was: I was running PHP 5.2.17 at the CLI, whereas my web server was running PHP 5.3.13.

问题是：我在 CLI 上运行 PHP 5.2.17，而我的 Web 服务器运行 PHP 5.3.13。

The resolution is: Use

决议是：使用

/usr/local/php53/bin/php artisan <command>

when running artisan commands at the CLI. This will ensure that all of my artisan commands are run using PHP 5.3 and above, which satisfies Laravel's PHP 5.3+ requirements.

在 CLI 中运行 artisan 命令时。这将确保我所有的 artisan 命令都使用 PHP 5.3 及更高版本运行，满足 Laravel 的 PHP 5.3+ 要求。

Namespaces and the __DIR__-pseud-constant were introduced in PHP 5.3. It seems you are running an old version. You should update to at least 5.3.

命名空间和__DIR__-pseud-constant 是在 PHP 5.3 中引入的。看来您运行的是旧版本。您应该至少更新到 5.3。
