如何调试 Gulp 任务?

问题描述

如何使用诸如 Google Chrome 调试器之类的调试器来调试在我的 gulpfile.js 中定义的 gulp 任务，逐行执行任务的代码?

How do I debug a gulp task defined in my gulpfile.js with a debugger such as the Google Chrome debugger, stepping through the task's code line by line?

推荐答案

使用 Node.js 6.3+ 版本，您可以使用 --inspect flag 在运行你的任务时.

With Node.js version 6.3+ you can use the --inspect flag when running your task.

调试名为 css 的 gulp 任务:

To debug a gulp task named css:

1. 找出你的 gulp 可执行文件在哪里.如果 gulp 安装在本地，它将位于 node_modules/.bin/gulp.如果 gulp 已全局安装，请在终端中运行 which gulp (Linux/Mac) 或 where gulp (Windows) 以找到它.

1. Find out where your gulp executable lives. If gulp is installed locally, this will be at node_modules/.bin/gulp. If gulp is installed globally, run which gulp (Linux/Mac) or where gulp (Windows) in a terminal to find it.

根据您的 Node.js 版本运行这些命令之一.如果需要，请将 ./node_modules/.bin/gulp 替换为步骤 1 中 gulp 安装的路径.

Run one of these commands according to your version of Node.js. If required, replace ./node_modules/.bin/gulp with the path to your gulp installation from step 1.

• Node.js 6.3+:node --inspect --debug-brk ./node_modules/.bin/gulp css
• Node.js 7+:node --inspect-brk ./node_modules/.bin/gulp css

使用 Chrome 浏览到 chrome://inspect.

Use Chrome to browse to chrome://inspect.

--debug-brk (Node.js 6.3+) 和 --inspect-brk (Node.js 7+) 标志用于暂停代码执行在任务的第一行代码上.这让您有机会在任务完成之前打开 Chrome 调试器并设置断点.

The --debug-brk (Node.js 6.3+) and --inspect-brk (Node.js 7+) flags are used to pause code execution on the first line of code of your task. This gives you a chance to open up the Chrome debugger and set breakpoints before the task finishes.

如果您不希望调试器在第一行代码处暂停，只需使用 --inspect 标志.

If you don't want the debugger to pause on first line of code, just use the --inspect flag.

您还可以安装 Node.js Inspector Manager (NIM) Chrome 扩展以帮助完成第 3 步.这将自动打开一个 Chrome 选项卡，调试器已准备就绪，作为手动浏览 URL 的替代方法.

You can also install the Node.js Inspector Manager (NIM) extension for Chrome to help with step 3. This will automatically open up a Chrome tab with the debugger ready to go, as an alternative to manually browsing to a URL.
