无法用自制软件安装php7或php 7.1

我正在关注具有相同序列的几个链接,即此示例.我无法成功完成任务.这是终端的输出

MacBook-Pro-4:/ SHennessy$ brew tap homebrew/dupes
MacBook-Pro-4:/ SHennessy$ brew tap homebrew/versions
MacBook-Pro-4:/ SHennessy$ brew tap homebrew/homebrew-php
MacBook-Pro-4:/ SHennessy$ brew unlink php56
Error: No such keg: /usr/local/Cellar/php56
MacBook-Pro-4:/ SHennessy$ brew install php70
==> Installing php70 from homebrew/php
Error: You must `brew link libpng` before homebrew/php/php70 can be installed
MacBook-Pro-4:/ SHennessy$ brew link php70
Error: No such keg: /usr/local/Cellar/php70
MacBook-Pro-4:/ SHennessy$

如果有人有任何想法会很棒,请提前感谢.

安装php71时,我或多或少有同样的问题.

要解决它,我不得不删除/usr/local/Cellar/php71使用sudo rmdir -rf /usr/local/opt/php71然后:

brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/homebrew-php
brew install php71

希望能帮助到你.

现在一切都已经过时了

所有人都迁移到了 homebrew/homebrew-core
