如何将 MCRYPT 路径设置回 MAMP Pro答案

【问题标题】：How to set MCRYPT path back to MAMP Pro如何将 MCRYPT 路径设置回 MAMP Pro

【问题描述】：

我已经使用 PHP 7.2 在 MAMP Pro 上安装了 MCRPYT，并且能够运行我的旧项目 Laravel 4.2。

这是我的 MAMP PHP.ini 中的列表

extension=mcrypt.so

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
extension_dir = "/Applications/MAMP/bin/php/php7.2.1/lib/php/extensions/no-debug-non-zts-20170718/"

但是当我运行 which mcrypt 时，它默认为 /usr/local/bin/mcrypt，我认为它应该在 MAMP Pro 下。

我之所以问这个是因为，我想将我的项目 Laravel 4.2 升级到 5.0。这是我尝试安装新的 Laravel 5.0 时的问题

  To enable extensions, verify that they are enabled in your .ini files:
    - /Applications/MAMP/bin/php/php7.2.1/conf/php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

注意

如果你想知道我是如何使用带有 MCrypt 的 PHP 7.2 运行 Laravel 4.2 的。检查此链接。

【问题讨论】：

很确定 mcrypt 自 PHP 7.2 以来已被删除......你真的想使用 Laravel 5.0 吗？也许您可以安装 Laravel 6 的新副本并将内容移到它上面
我现在正在运行实验，因为我拥有的项目目前正在使用 laravel 4.2 并检查是否将其升级到 5.0 对我来说很容易，尽管这并不像预期的那样。我遵循本指南medium.com/@tomgrohl/…，该项目在 laravel 4.2 上运行良好。

【解决方案1】：

如果php版本低于7.1：

安装并启用 mcrypt：

sudo apt-get install mcrypt php-mcrypt
sudo phpenmod mcrypt

尝试找到您的 php.ini 并打开它。

vim php.ini

在这个文件中加入一行

extension=mcrypt.so

重启php和apache。

其他

尝试将您的 laravel 版本升级到 5.5 以上。喜欢：

     "laravel/framework": "5.5.*"

由于您安装的框架是 5.0，它需要PHP >= 5.4, PHP < 7。见：https://laravel.com/docs/5.0#server-requirements

【讨论】：

我认为不会有 PHP >= 7.2.0 的 mcrypt 包
@lagbox 你是对的。在搜索 php.net 参考后，它说许多（所有）mcrypt 函数自 PHP 7.1.0 起已被弃用。
我都在我的 osx 上运行 mcrypt。一个用osx，另一个用mamp pro。问题是，我忘记了如何将 mcrypt 指向 mamp pro，第二，我放错了有它的指南的网站。如果有的话，请在我的问题中查看我的注释以供参考。
@iMarkDesigns 那么，升级你的胸肌吗？
@TsaiKoga 是的。它已升级。
