Serverless Framework VSCode调试配置无法执行问题求助

我正在用Serverless Framework为Web应用开发Node API后端，使用Windows 11系统上的VSCode作为IDE。启动VSCode的运行与调试组件后立即报错，无法解决。

我的launch.json配置 #

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "run SLS",
      "program": "${workspaceRoot}/api/fq-transcribe/node_modules/.bin/sls",
      "args": ["invoke", "local", "-f", "fqTranscribe", "-p", "./test-events/event.json"]
    }
  ]
}

报错信息 #

Uncaught SyntaxError C:\Users\david\build\frequency\api\fq-transcribe\node_modules\.bin\sls:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
          ^^^^^^^

sls文件内容 #

#!/bin/sh
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

case `uname` in
    *CYGWIN*|*MINGW*|*MSYS*) basedir=`cygpath -w "$basedir"`;;
esac

if [ -x "$basedir/node" ]; then
  exec "$basedir/node"  "$basedir/../serverless/bin/serverless.js" "$@"
else 
  exec node  "$basedir/../serverless/bin/serverless.js" "$@"
fi

问题原因 #

你把Shell脚本（sls）当成Node.js脚本运行了，Node无法解析Shell语法，导致抛出语法错误。

解决办法 #

方法1：直接调用Serverless的Node.js入口文件 #

修改launch.json，将program指向Serverless的核心JS文件，跳过Shell脚本：

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "run SLS",
      "program": "${workspaceRoot}/api/fq-transcribe/node_modules/serverless/bin/serverless.js",
      "args": ["invoke", "local", "-f", "fqTranscribe", "-p", "./test-events/event.json"]
    }
  ]
}

方法2：改用Shell调试类型 #

如果想保留调用sls脚本，将调试类型改为shell（需确保VSCode安装了Shell调试相关插件）：

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "shell",
      "request": "launch",
      "name": "run SLS",
      "command": "${workspaceRoot}/api/fq-transcribe/node_modules/.bin/sls",
      "args": ["invoke", "local", "-f", "fqTranscribe", "-p", "./test-events/event.json"]
    }
  ]
}
