你不需要在visual studio代码中设置运行javascript、python等代码的环境，你所要做的就是安装代码运行器扩展，然后选择你想要运行的代码的一部分，然后点击右上角的运行按钮。

对于windows:只需将.js文件的文件关联更改为node.exe

1) Take VSCode
2) Right click on the file in left pane
3) Click "Reveal in explorer" from context menu
4) Right click on the file -> Select "Open with" -> Select "Choose another program"
5) Check box "Always use this app to open .js file"
6) Click "More apps" -> "Look for another app in PC"
7) Navigate to node.js installation directory.(Default C:\Program Files\nodejs\node.exe"
8) Click "Open" and you can just see cmd flashing
9) Restart vscode and open the file -> Terminal Menu -> "Run active file".

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
        }
    ]
}

使用这个类名tempCodeRunnerFile运行java文件而不保存

public class tempCodeRunnerFile{
    public static void main(String[] args) {
        System.out.println("aaaaaa");
    }
}

只需安装nodemon并运行

nodemon your_file.js

在vs code终端上。

如果您的节点安装在您的机器上

只要在VSCODE中打开终端，输入node yourfile.js，就是这样
