用npm安装nodemon Init nodemon: npm Init 打开的包。Json，并将其更改为: ｛ “名称”:“JavaScript”, “版本”:“1.0.0”, “描述”:“”, “主要”:“{文件名}. js”, "脚本":{ "test": "echo \"错误:没有测试指定的\" && exit 1"， "start": "nodemon {filename}.js" }， “关键词”:[], “作者”:“”, “许可证”:“ISC” ｝ 在终端上写这个命令:npm start

过程

*(前言)

步骤如下: 根据我的记忆，没有严格测试步骤…(可能会错过一些东西?) 以后的版本可能会有一些不同的变化 事物的自动设置(例如:环境路径)可能是不同的 在Win10

运行纯js

download & install Vscode download & install Node.js from the the offical website, eg: in G:\nodejs\node.exe open Vscode -> open your workspace folder eg: MyTestSpace -> create a new file call eg: test.js write a code console.log('-----test-----'); in test.js go to the Run and Debug panel (ctrl+shift+d) > Run drop down list at the top > Add Config (MyTestSpace) > a launch.json should be auto generated for you > at the auto-completetion popup > select Node.js: Launch Program > auto complete config fill in > rename the program to the path where your test.js locate your launch.json should look something like this:: { "version": "0.2.0", "configurations": [ { "type": "node", "request": "launch", "name": "Launch Program", "program": "${workspaceFolder}/test.js", }, ], } go back to the Run drop down list > select Launch Program (MyTestSpace) > click the Run button in your Debug Console should see the following:: G:\nodejs\node.exe .\test.js -----test----- a graph for demo naming might be different (just a ugly rough draft for demo [[(just try to post an answer wrote with little effort...)]]) (ignore unnecessary staff...)

运行js & html(简要介绍)

have a eg: main_test.html file, with a <script> tag refer to the test.js in the Run drop down list > add config > select Chrome > auto complete launch.json > change path to main_test.html eg: { "type": "chrome", "request": "launch", "name": "Open main_test.html", "file": "h:\\Book\\debug\\LXPI\\OEBPS\\lib_new2\\libNt\\crossFileHtse\\build_HighlightTypeset_ReadHtse\\main_test.html", }, select that chrome launch config > Run > html is opened up in your browser & console log printed

有一个更简单的方法来运行JavaScript，不需要配置:

安装代码运行器扩展 在文本编辑器中打开JavaScript代码文件，然后使用快捷键Control+Alt+N(或者在macOS上使用⌃Control+“选项”+“N”)，或者按F1，然后选择/键入“运行代码”，代码将运行，输出将显示在“输出窗口”中。

此外，您还可以选择部分JavaScript代码并运行代码片段。扩展也适用于未保存的文件，所以你可以创建一个文件，将其更改为Javascript并快速编写代码(当你只需要尝试一些快速的东西)。非常方便!

这需要NodeJS，否则它将无法工作。

这很简单，当你在VS Code中创建一个新文件并运行它时，如果你还没有配置文件，它会为你创建一个，你唯一需要设置的是“program”值，并将其设置为你的主JS文件的路径，如下所示:

{
    "version": "0.1.0",
    // List of configurations. Add new configurations or edit existing ones.  
    // ONLY "node" and "mono" are supported, change "type" to switch.
    // ABSOLUTE paths are required for no folder workspaces.
    "configurations": [
        {
            // Name of configuration; appears in the launch configuration drop down menu.
            "name": "Launch",
            // Type of configuration. Possible values: "node", "mono".
            "type": "node",
            // ABSOLUTE path to the program.
            "program": "C:\\test.js", //HERE YOU PLACE THE MAIN JS FILE
            // Automatically stop program after launch.
            "stopOnEntry": false,
            // Command line arguments passed to the program.
            "args": [],
            // ABSOLUTE path to the working directory of the program being debugged. Default is the directory of the program.
            "cwd": "",
            // ABSOLUTE path to the runtime executable to be used. Default is the runtime executable on the PATH.
            "runtimeExecutable": null,
            // Optional arguments passed to the runtime executable.
            "runtimeArgs": [],
            // Environment variables passed to the program.
            "env": { },
            // Use JavaScript source maps (if they exist).
            "sourceMaps": false,
            // If JavaScript source maps are enabled, the generated code is expected in this directory.
            "outDir": null
        }, 
        {
            "name": "Attach",
            "type": "node",
            // TCP/IP address. Default is "localhost".
            "address": "localhost",
            // Port to attach to.
            "port": 5858,
            "sourceMaps": false
        }
    ]
}

在我看来，这是你最快的方法;

在visual studio代码上打开集成终端(查看>集成终端) 输入“node filename.js” 按回车键

注意:节点设置需要。(如果你有自制程序，只需在终端上输入“brew install node”)

注2:如果你还没有自制和节点，强烈推荐。

祝你有愉快的一天。

另一种方法是打开终端ctrl+ '执行节点。现在您有了一个活动的节点REPL。您现在可以将您的文件或选定的文本发送到终端。为了做到这一点，打开VSCode命令面板(F1或ctrl+shift+p)并执行>在活动终端运行选定的文本或>在活动终端运行活动文件。

如果在执行代码之前需要一个干净的REPL，则必须重新启动节点REPL。这是在终端中使用节点REPL ctrl+c ctrl+c退出它，并键入node开始新的。

您可能可以将命令面板命令按键绑定到您希望的任何键。

node应该安装在您的路径中
