GitHub issues 找到了解决方案，因此在此记录一下。

安装V8

1. 确保您的系统上以前没有安装v8。
2. 下载此v8自制公式(v8 7.4.288.25) https://raw.githubusercontent.com/Homebrew/homebrew-core/0a6171330678879285f2c566db9349da421d6f62/Formula/v8.rb (需翻墙)
3. 使用下载的公式安装v8：brew install v8.rb

安装v8js扩展

1. 将v8js克隆到本地： git clone https://github.com/phpv8/v8js
2. 从源代码构建v8js：

   cd v8js
   phpize
   ./configure CXXFLAGS="-Wno-c++11-narrowing" --with-v8js="/usr/local/Cellar/v8/7.4.288.25/libexec"
   make
   make test
   make install

在PHP中启用v8js

1. 查找php.ini文件

   ➜  ~ php --ini
   Configuration File (php.ini) Path: /usr/local/etc/php/7.2
   Loaded Configuration File:         /usr/local/etc/php/7.2/php.ini
   Scan for additional .ini files in: /usr/local/etc/php/7.2/conf.d
   Additional .ini files parsed:      /usr/local/etc/php/7.2/conf.d/ext-opcache.ini,

2. 打开php.ini文件

   vim /usr/local/etc/php/7.2/php.ini

3. 将此行添加到开头并保存ini文件: extension =”v8js.so”
4. 重新启动PHP

   brew services restart php
