问题描述
我想为 PHP 安装 v8js 扩展，当我尝试使用此命令安装它时 pecl install v8js 它在终端显示此日志：
WARNING: channel "pecl.PHP.net" has updated its protocols,use "pecl channel-update pecl.PHP.net" to update

Please provide the installation prefix of libv8 [autodetect] :
而且我不知道日志 Please provide the installation prefix of libv8 [autodetect] : 的最后一行是什么意思，所以我尝试通过按 Enter 键跳过它并继续该过程并显示此日志：

所以我尝试安装 v8 引擎以使用此命令 apt-get install libv8-dev 解决此问题，但它显示此日志：
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note,selecting 'libnode-dev' instead of 'libv8-dev'
libnode-dev is already the newest version (12.21.0~dfsg-3ubuntu1).
