mac下多个php版本切换(可操作版)

参考了多个文章,并且进行测试实践,总结了如下正确的操作方式

实践

适用版本:

OS X Version:    10.12.3 (16D32)
--------
Homebrew 1.3.2
Homebrew/homebrew-core (git revision aeab0; last commit 2017-09-14)
--------
PHP Version in use:    php71 56

并且,前提你已经按照php56了

1.brew update

需要先更新brew的软件仓库目录

2.brew upgrade

根据之前的update更新的软件仓库目录,用upgrade来更新所有软件和相关依赖,为了保证安装软件的正确

备注:
用doctor进行打印出错的详细地方,安装顺利的话,不需要使用

brew doctor

3.brew install php71

需要先安装这个php仓库

brew tap josegonzalez/homebrew-php

然后安装php71

brew install php71

需要注意的是,这里需要先解除homebrew与php56的关联,然后再安装php71

brew unlink php56

4.安装php-version

安装php-version

brew install php-version

设置php-version的初始化

source $(brew --prefix php-version)/php-version.sh

这样就可以使用多个版本了

php-version   
* 5.6.30
  7.1.8
➜  ~ php -version
PHP 5.6.30 (cli) (built: Sep 15 2017 14:11:24) (DEBUG)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies


➜  ~ php -version                 
PHP 7.1.8 (cli) (built: Sep 15 2017 14:26:34) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies
➜  ~ php-version 
  5.6.30
* 7.1.8

遇到问题

报错:

dyld: Library not loaded: /usr/local/opt/libpng/lib/libpng16.16.dylib
Referenced from: /usr/local/bin/php
Reason: Incompatible library version: php requires version 45.0.0 or later, but libpng16.16.dylib provides version 38.0.0
Abort trap: 6

dyld: Library not loaded: /usr/local/opt/libpng/lib/libpng16.16.dylib

  Reason: Incompatible library version: php requires version 48.0.0 or later, but libpng16.16.dylib provides version 45.0.0

其实报错都差不多,都是说libpng版本有问题,解决的办法有2个:

1.更新libpng,如果解决不了,就跳到2选项
