为什么我的项目安装了错误的Angular版本？

Question

我的项目似乎没有最新的Angular代码，但我不确定原因。

这是我的package.json

  "devDependencies": {
    "@angular/common": "2.0.0",
    "@angular/compiler": "2.0.0",
    "@angular/core": "2.0.0",
    "@angular/forms": "2.0.0",
    "@angular/http": "2.0.0",

这是node_modules/@angular/compiler/src/metadata_resolver.js中的一项功能，我需要修补以修复this problem

function componentModuleUrl(reflector, type, cmpMetadata) {
    if (cpl.isStaticSymbol(type)) {
        return staticTypeModuleUrl(type);
    }
    if (isPresent(cmpMetadata.moduleId)) {
        var moduleId = cmpMetadata.moduleId;
        var scheme = getUrlScheme(moduleId);
        return isPresent(scheme) && scheme.length > 0 ? moduleId :
            "package:" + moduleId + MODULE_SUFFIX;
    }
    return reflector.importUri(type);
}

这是Angular GitHub repository

中的相同功能（在TypeScript中）

function componentModuleUrl(
    reflector: ReflectorReader, type: Type<any>, cmpMetadata: Component): string {
  if (cpl.isStaticSymbol(type)) {
    return staticTypeModuleUrl(type);
  }

  const moduleId = cmpMetadata.moduleId;

  if (typeof moduleId === 'string') {
    const scheme = getUrlScheme(moduleId);
    return scheme ? moduleId : `package:${moduleId}${MODULE_SUFFIX}`;
  } else if (moduleId !== null && moduleId !== void 0) {
    throw new Error(
        `moduleId should be a string in "${stringify(type)}". See <shortened link that stackoverflow does not allow> for more information.\n` +
        `If you're using Webpack you should inline the template and the styles, see <shortened link that stackoverflow does not allow>`);
  }

  return reflector.importUri(type);
}

您的版本正确。您只需要选择正确的标签
