从php文档运行gulp“ npm start”？

Question

我正在尝试运行shell命令以进行gulp编译。

我通常跑：

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

npm start

并且gulp文件编译良好。

我需要知道是否有一种编译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，我得到了一个日志文件，而不是正确的编译。

Answer 1

首先将要运行的脚本保存在文件中，例如compile.sh 。 授予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;

这足以让您使用PHP运行脚本。

您可能需要使用绝对路径引用npm和任何目录。 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它可以工作。
