从 php 文档运行 gulp“npm start”？

Question

我正在尝试运行一个 shell 命令来编译 gulp。

我经常跑：

cd
cd /var/www/html/
npm uninstall gulp --save
npm install gulp --save

npm start

gulp 文件编译良好。

我需要知道是否有编译 gulp 文件的方法（本质上是从 php 文档运行 npm start 命令。

$output = shell_exec('./compileNpmStart.sh');

// display $output
echo $output;

这似乎可以编译但是：

编译后我得到一个日志文件而不是正确编译。

Answer 1

首先将要运行的脚本保存在文件中，例如compile.sh。给脚本正确的运行权限，例如chmod 755 compile.sh.

然后，在您的 PHP 脚本中，添加以下内容：

<?php
// allow script to run for up to 10 minutes
set_time_limit(600); // seconds

// output of script will be saved in $output
$output = shell_exec('./compile.sh');

// display $output
echo $output;

这应该足以让您使用 PHP 运行脚本。

您可能需要引用npm 和任何使用绝对路径的目录。通过命令行运行which npm 以获取要使用的完整路径。通过命令行运行脚本以确保其正常工作。
