无法创建 Laravel 项目，因为缺少 mcrypt 扩展

can't create a Laravel project because mcrypt extension is missing

提问by rogdawg

OK, I have seen many posts about this, and I have spent the entire day working through them to solve this issue, with no success.

好的，我看过很多关于这个的帖子，我花了一整天的时间来解决这个问题，但没有成功。

I am trying to create a Laravel project. I am using a Mac (Yosemite), which is running PHP 5.5.14. There is also an older version of PHP on the machine. When I try to create a project from the command line using "laravel new projectname", no errors are reported, but the command just creates an empty folder named with the project name. I get the "Crafting application..." and "Application ready! Build something amazing" messages but, again, only an empty folder.

我正在尝试创建一个 Laravel 项目。我使用的是运行 PHP 5.5.14 的 Mac (Yosemite)。机器上还有一个旧版本的PHP。当我尝试使用“laravel new projectname”从命令行创建项目时，没有报告任何错误，但该命令只是创建了一个以项目名称命名的空文件夹。我收到“正在制作应用程序...”和“应用程序准备就绪！构建一些惊人的东西”消息，但同样只有一个空文件夹。

If I try to use this command: composer create-project laravel/laravel projectname

如果我尝试使用此命令： composer create-project laravel/laravel projectname

I get this:

我明白了：

Installing laravel/laravel (v5.0.16) - Installing laravel/laravel (v5.0.16) Downloading: 100%

安装 laravel/laravel (v5.0.16) - 安装 laravel/laravel (v5.0.16) 下载：100%

Created project in projectnameLoading composer repositories with package information Installing dependencies (including require-dev) from lock file Your requirements could not be resolved to an installable set of packages.

在projectname 中创建项目 加载带有包信息的Composer存储库 从锁定文件安装依赖项（包括 require-dev） 您的需求无法解析为一组可安装的包。

Problem 1 - Installation request for laravel/framework v5.0.16 -> satisfiable by laravel/framework[v5.0.16]. - laravel/framework v5.0.16 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.

问题 1 - laravel/framework v5.0.16 的安装请求 -> laravel/framework[v5.0.16] 可满足。- laravel/framework v5.0.16 需要 ext-mcrypt * -> 您的系统中缺少请求的 PHP 扩展 mcrypt。

In the terminal, if I enter this: which php I get: /usr/bin/php /usr/bin/php -v I get: PHP 5.5.14 (cli) (built: Sep 9 2014 19:09:25) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Xdebug v2.2.3, Copyright (c) 2002-2013, by Derick Rethans

在终端中，如果我输入：我得到哪个 php：/usr/bin/php /usr/bin/php -v 我得到：PHP 5.5.14 (cli)（构建：2014 年 9 月 9 日 19:09:25）版权所有 (c) 1997-2014 The PHP Group Zend Engine v2.5.0，版权所有 (c) 1998-2014 Zend Technologies with Xdebug v2.2.3，版权所有 (c) 2002-2013，Derick Rethans

I used homebrew to install autoconf and mcrypt with this command: brew install autoconf mcrypt

我使用自制软件通过以下命令安装 autoconf 和 mcrypt： brew install autoconf mcrypt

If I run that command again, I get: Warning: autoconf-2.69 already installed Warning: mcrypt-2.6.8 already installed

如果我再次运行该命令，我会得到：警告：已安装 autoconf-2.69 警告：已安装 mcrypt-2.6.8

Since I kept getting the error, I assumed it was installed in the wrong place so, I compiled and installed mcrypt myself using these instructions: [Install mcrypt php extension][1]. I used PHP version 5.5.14 during the install. Mcrypt was installed in this directory: /usr/lib/php/extensions/no-debug-non-zts-20121212/

由于我不断收到错误，我认为它安装在错误的位置，所以我使用以下说明编译并安装了 mcrypt：[安装 mcrypt php 扩展][1]。我在安装过程中使用了 PHP 5.5.14 版。Mcrypt安装在这个目录：/usr/lib/php/extensions/no-debug-non-zts-20121212/

I have restarted Apache. I have checked my .bash_profile to make sure /usr/bin is in my Path.

我已经重新启动了 Apache。我已经检查了我的 .bash_profile 以确保 /usr/bin 在我的路径中。

If I create a page with phpinfo() and view it in my browser, I see that mcrypt is listed in the "Module Authors" section of the page. It just lists the names of the people who created the module.

如果我使用 phpinfo() 创建一个页面并在我的浏览器中查看它，我会看到 mcrypt 列在页面的“模块作者”部分中。它仅列出创建模块的人员的姓名。

I am stumped. I look forward to any suggestions that people might offer (I really don't want to install a virtual box, or anything like that. Surely, I can get this module installed in the right place!)

我难住了。我期待着人们可能提供的任何建议（我真的不想安装虚拟盒子或类似的东西。当然，我可以在正确的位置安装这个模块！）

Thanks very much!

非常感谢！

I got this exact same problem too. You have to find php.inifor php cli and add extension=mcrypt.so

我也遇到了完全相同的问题。你必须找到php.iniphp cli 并添加extension=mcrypt.so

My system is running LAMPP server with preinstalled PHP. So, here's what I do:

我的系统正在运行预装 PHP 的 LAMPP 服务器。所以，这就是我要做的：

Install mcrypt extension

安装 mcrypt 扩展

I tried both:

我都试过：

sudo apt-get install mcrypt
sudo apt-get install php5-mcrypt

Configure php.ini for CLI

为 CLI 配置 php.ini

Then, edit php.ini located in /opt/lampp/etc/php5/cli/php.iniadd extension=mcrypt.soon Dynamic Extensionsection (anywhere is fine I think). Don't forget to restart your server.

然后，位于编辑php.ini中/opt/lampp/etc/php5/cli/php.ini添加extension=mcrypt.so的动态扩展部分（任何地方是好的，我认为）。不要忘记重新启动服务器。

Try using composer to install laravel

尝试使用composer安装laravel

Now, you can run whatever method you want to install laravel. I download Laravel 5 manually, unzip, then install using composer installcommand. I think your command composer create-project laravel/laravel projectnamewould've run smoothly too.

现在，你可以运行任何你想安装 Laravel 的方法。我手动下载 Laravel 5，解压，然后使用composer install命令安装。我认为你的命令composer create-project laravel/laravel projectname也会顺利运行。
