mac下多個php版本切換(可操作版)
參考了多個文章,並且進行測試實踐,總結瞭如下正確的操作方式
實踐
適用版本:
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
並且,前提你已經按照php56了
1.brew update
需要先更新brew的軟體倉庫目錄
2.brew upgrade
根據之前的update更新的軟體倉庫目錄,用upgrade來更新所有軟體和相關依賴,為了保證安裝軟體的正確
備註:
用doctor進行列印出錯的詳細地方,安裝順利的話,不需要用
brew doctor
3.brew install php71
需要先安裝這個php倉庫
brew tap josegonzalez/homebrew-php
然後安裝php71
brew install php71
要注意的是,這裡需要先解除homebrew與php56的關聯,然後再安裝php71
brew unlink php56
4.安裝php-version
##安裝php-versionbrew install php-version
source $(brew --prefix php-version)/php-version.sh
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
遇到問題##報錯:
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 Referenced from: /usr/local/Cellar/php70/7.0.22_14/bin/php Reason: Incompatible library version: php requires version 48.0.0 or later, but libpng16.16.dylib provides version 45.0.0
其實報錯都差不多,都是說libpng版本有問題,解決的辦法有2個:
1.更新libpng,如果解決不了,就跳到2選項
brew upgrade libpng
2.不要用php70,用php71
7.0怎麼測試都不行,切換7.1就好了
