php - 无法在 macOS Sierra 上使用 Homebrew 安装 PHP 7

Question

我正在尝试设置 Laravel 的 Valet，作为依赖项，它需要 PHP 7。当我尝试使用 Homebrew 安装 PHP 7 时，出现以下错误:

Configuring SAPI modules
checking for Apache 2.0 handler-module support via DSO through APXS... 

Sorry, I cannot run apxs.  Possible reasons follow:

1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)

The output of /usr/sbin/apxs follows:
apxs:Error: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.12.xctoolchain/usr/local/bin/apr-1-config not found!.

configure: error: Aborting

这是全新安装的 MacOS Sierra(实际版本，不是测试版)和全新安装的 Homebrew(已更新)。我已经安装、运行并同意 Xcode 许可协议(protocol)。

我不知道这些错误是什么意思。我该如何修复它们？

Answer 1

是的，我已经弄明白了。我在下面发布了成功安装所需组件的步骤，以防其他人偶然发现此问题:

1).确保 Homebrew 是最新的:

brew update

2).通过确保安装了 Xcode 然后在终端中键入以下内容来修复 PHP 7 错误:

brew install apr apr-util
sudo mkdir -p /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.12.xctoolchain/usr/local/bin/
sudo ln -s /usr/local/opt/apr/bin/apr-1-config /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.12.xctoolchain/usr/local/bin/
sudo ln -s /usr/local/opt/apr-util/bin/apu-1-config /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.12.xctoolchain/usr/local/bin/

3).运行以下命令(否则 PHP 安装会提示缺少 libz):

xcode-select --install

4).您现在可以使用 Homebrew 安装 PHP 7:

brew install homebrew/php/php70
