在 Visual Studio 代码中运行 babel-node

Question

通常通过命令行启动，我可以输入：

babel-node server.js

当我尝试设置它以便断点和在我收到的 Visual Studio 代码中不起作用的内容时：

/Users/me/proj/node_modules/babel-cli/lib/babel-node.js --debug-brk=31893 --nolazy server.js 
/Users/me/proj/node_modules/babel-cli/lib/babel-node.js: line 1: /Applications: is a directory
/Users/me/proj/node_modules/babel-cli/lib/babel-node.js: line 3: /Applications: is a directory
/Users/me/proj/node_modules/babel-cli/lib/babel-node.js: line 4: Dockerfile: command not found
/Users/me/proj/node_modules/babel-cli/lib/babel-node.js: line 5: syntax error near unexpected token `('
/Users/me/proj/node_modules/babel-cli/lib/babel-node.js: line 5: ` * when found, before invoking the "real" _babel-node(1) executable.'

我推测这与从该目录调用可执行文件有关，而不是从与 server.js 文件相同的目录调用 - 但我真的不知道。

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "node",
            "request": "launch",
            "program": "${workspaceRoot}/server.js",
            "stopOnEntry": false,
            "args": [],
            "cwd": "${workspaceRoot}",
            "preLaunchTask": null,
            "runtimeExecutable": "${workspaceRoot}/node_modules/babel-cli/lib/babel-node.js",
            "runtimeArgs": [
                "--nolazy"
            ],
            "env": {
                "NODE_ENV": "development"
            },
            "externalConsole": false,
            "sourceMaps": false,
            "outDir": null
        },
        {
            "name": "Attach",
            "type": "node",
            "request": "attach",
            "port": 5858,
            "address": "localhost",
            "restart": false,
            "sourceMaps": false,
            "outDir": null,
            "localRoot": "${workspaceRoot}",
            "remoteRoot": null
        }
    ]
}

发生错误是因为babel-node.js 文件不是babel-node 可执行文件，而是一个添加节点标志的包装文件：

babel-node.js

/* eslint indent: 0 */

/**
 * This tiny wrapper file checks for known node flags and appends them
 * when found, before invoking the "real" _babel-node(1) executable.
 */

要解决此问题，应将babel-node 二进制文件的位置设置为runtimeExecutable 属性的值。地点是：

"${workspaceRoot}/node_modules/.bin/babel-node"
