[英]Even specifing "type":"module" in package.json for importing external file, still throwing SyntaxError: Cannot use import statement outside a module
[英]VSC Debugger throwing SyntaxError: Cannot use import statement outside a module
在最近更新 Visual Studio Code 之前,我能够使用此launch.json
配置调试用 TypeScript 编写的 Node.js 应用程序
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.

"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Debug API",
"protocol": "inspector",
"program": "${workspaceFolder}/apps/api/src/main.ts",
"outFiles": ["${workspaceFolder}/dist/apps/api/main.js"],
"sourceMaps": true
}
]
}
但是现在我收到了这个错误
import * as express from 'express';
^^^^^^

知道如何解决这个问题吗? 或者至少让它工作,同时 VSC 团队在他们的 GitHub https://github.com/microsoft/vscode/issues/102834上提供答案
您可以执行以下操作:
在package.json
中添加(如果尚不存在)构建步骤,如下所示;
"ci-build": "npx tsc",
我在tsconfig.json
中有以下选项;
"compilerOptions": { "outDir": "dist", "rootDir": "src", "module": "commonjs" "sourceMap": true, "lib": ["esnext", "dom"], "strict": true, "esModuleInterop": true, "target": "es2017" }
注意:确保将sourceMap
设置为true
我的launch.json
看起来像这样;
{ "type": "node", "request": "launch", "name": "Build Project", "program": "${workspaceFolder}/src/index.ts", "preLaunchTask": "npm: ci-build", "sourceMaps": true, "smartStep": true, "internalConsoleOptions": "openOnSessionStart", "outFiles": ["${workspaceFolder}/dist/**/*.js"] }

根据对这个 github 问题的评论,VSC 团队已经为 Visual Studio Code 1.48 版本提供了修复:
{
"type": "node",
"request": "launch",
"name": "Debug launcher",
"protocol": "inspector",
"program": "${workspaceFolder}/apps/launcher/src/main.ts",
"outFiles": ["${workspaceFolder}/dist/**/*.js"],
"sourceMaps": true
}
