Cannot find namespace NodeJS after webpack upgrade
提问by Felix
I have Angular2 application that is built with WebPack. I upgraded WebPack from v1.8 to v2, and everything seems to be working fine. The only problem is that the old code has the following:
我有使用 WebPack 构建的 Angular2 应用程序。我将 WebPack 从 v1.8 升级到 v2，一切似乎都运行良好。唯一的问题是旧代码有以下几点：
import Timer = NodeJS.Timer;
....
apptInterval: Timer;
....
this.apptInterval = setInterval(() => { ... }, 1000);
After the upgrade this gives me an error: TS2503: Cannot find namespace 'NodeJS'.
升级后，这给了我一个错误： TS2503: Cannot find namespace 'NodeJS'.
tsconfig.json looks like this:
tsconfig.json 看起来像这样：
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es2015", "dom"],
"noImplicitAny": true,
"suppressImplicitAnyIndexErrors": true
}
}
The docs for Angular/Webpack no longer have typings.json; however, even if I copy from Webpack 1 directory, it doesn't help. The content is typings.json is
Angular/Webpack 的文档不再有typings.json; 但是，即使我从 Webpack 1 目录复制，也无济于事。内容是typings.json是
{
"globalDependencies": {
"jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
"node": "registry:dt/node"
}
}
Interesting that if I remove references to NodeJS, everything works fine. Like this:
有趣的是，如果我删除对 NodeJS 的引用，一切正常。像这样：
apptInterval: any;
....
this.apptInterval = setInterval(() => { ... }, 1000);
If I look under F12 debugger, the type of apptInterval is ZoneTask. I am sure there is a way to make it strong-typed, but it escapes me. The only suggestion I found was to run typings install dt~node --global --save-dev(which essentially updates typings.json, but doesn't help.
如果我查看 F12 调试器，apptInterval 的类型是ZoneTask. 我确信有一种方法可以使它成为强类型，但它让我无法理解。我发现的唯一建议是运行typings install dt~node --global --save-dev（它基本上更新了typings.json，但没有帮助。

If you also have tsconfig.app.jsonin your working directory, try to add the attribute nodeto the typesfield. Like:
如果您的工作目录中还有tsconfig.app.json，请尝试将属性节点添加到types字段。喜欢：
{
"extends": "../tsconfig.json",
"compilerOptions": {
"outDir": "../out-tsc/app",
"module": "es6",
"baseUrl": "",
"types": ["node"] --> ADD THIS
},
"exclude": [
"test.ts",
"**/*.spec.ts"
]
}

For [email protected]+, use @types:
对于 [email protected]+，使用@types：
npm install -D @types/node @types/jasmine
If you still want to hang on to typings, include typings/index.d.tsto your tsconfig.json:
如果您仍然想继续使用typings，typings/index.d.ts请将其包含到您的 tsconfig.json 中：
{
"include": [ // or "files"
"typings/index.d.ts"
]
}

Adding node to the types didn't work for me, "types": ["node"]but adding to the type roots did
将节点添加到类型对我不起作用，"types": ["node"]但添加到类型根对我 有用
{
"compilerOptions":
{
...
"typeRoots": [
"node_modules/@types"
]
}
}
