Question

我正在使用angular2 我使用this project开始申请。

之后实施多语言支持

步骤： 1）执行命令

npm install @angular/compiler-cli @angular/platform-server --save

输出：

+ - UNMET PEER DEPENDENCY rxjs@5.0.0-rc.5`- UNMET PEER DEPENDENCY tslint@4.0.2

2）执行命令＆＃34; ./ node_modules / .bin / ng-xi18n＆＃34; 它给我以下错误

C：\项目\ TEMP \ PathTrak3 \的PathTrak＆GT;＆＃34; ./ node_modules /的.bin / NG-xi18n＆＃34; TypeError：无法读取属性＆＃39;创建＆＃39;未定义的在Function.Extractor.create（C：\ Projects \ temp \ PathTrak3 \ PathTrak \ node_modules \ @angular \ compiler-cli \ src \ extractor 的.js：69：45）在extract（C：\ Projects \ temp \ PathTrak3 \ PathTrak \ node_modules \ @angular \ compiler-cli \ src \ extract_i18n.js：7：34）在Object.main（C：\ Projects \ temp \ PathTrak3 \ PathTrak \ node_modules \ @angular \ tsc-wrapped \ src \ main.js：47：16）在对象。（C：\项目\ TEMP \ PathTrak3 \的PathTrak \ node_modules \ @angular \编译-CLI \ SRC \ extract_i18n.js： 14：9）在Module._compile（module.js：570：32）在Object.Module._extensions..js（module.js：579：10）在Module.load（module.js：487：32）在tryModuleLoad（module.js：446：12）在Function.Module._load（module.js：438：3）在Module.runMain（module.js：604：10）提取失败

由于此错误，我无法实施i18n。请在package.json文件中找到以下依赖项

 "dependencies": {
    "@angular/common": "2.1.1",
    "@angular/compiler": "2.1.1",
    "@angular/compiler-cli": "^2.4.1",
    "@angular/core": "2.1.1",
    "@angular/forms": "^2.1.1",
    "@angular/http": "2.1.1",
    "@angular/platform-browser": "2.1.1",
    "@angular/platform-browser-dynamic": "2.1.1",
    "@angular/platform-server": "^2.1.1",
    "@angular/router": "3.1.1",
    "@angularclass/conventions-loader": "^1.0.2",
    "@angularclass/hmr": "~1.2.0",
    "@angularclass/hmr-loader": "~3.0.2",
    "angular2-highcharts": "^0.4.0",
    "assets-webpack-plugin": "^3.4.0",
    "core-js": "^2.4.1",
    "http-server": "^0.9.0",
    "ie-shim": "^0.1.0",
    "rxjs": "^5.0.0-rc.1",
    "zone.js": "~0.6.17"
  }

是否在package.json文件中出现版本问题？请帮助

谢谢， Sardar Nale

Answer 1

我想这只是你的角度版本的不匹配。您应该为每个@angular软件包坚持使用相同的版本（路由器除外，它将是高级版本的主要版本，直到角度4发布）。

用你的......

npm install @angular/compiler-cli @angular/platform-server --save

......您似乎至少@angular/compiler-cli位于2. 4.1 ，可能而且@angular/platform-server位于2.4.1。由于您已将其他 @angular软件包设置为固定版本2. 1.1 ，因此会出现一些冲突。

注意：文档将始终假设您使用的是最新（稳定）角度版本。

那么如何解决它......

1。安装旧包

您可以通过添加@angular/compiler-cli＆amp;来安装旧软件包。 @angular/platform-server要修复package.json中的 2.1.1 （请不要忘记在此删除插入符号（^））。然后删除node_modules文件夹并再次运行npm install。

2。 ...或更新其他包

另一个选择是您将其他@angular软件包更新到最新的2.4.1版本。在这里，您必须使用package.json中的 2.4.1 替换 2.1.1 （路由器 3.4.1除外））。然后删除node_modules文件夹并再次运行npm install。

根据您的应用，您可能会遇到其他一些问题......您可能需要先查看Changelog。

仅供参考：当您在项目中安装新的@angular软件包时，请始终坚持使用您正在使用的版本。要在您的案例中安装特定版本，请注意{注释@2.1.1）：

npm install @angular/compiler-cli@2.1.1 @angular/platform-server@2.1.1 --save

...或全部更新到新版本; - ）
