angular2 i18n无法读取未定义的属性“create”

Question

我正在使用Angular2.br>我使用这个项目开始应用程序。

要实现多语言支持，请遵循以下文档

步骤:1）执行命令

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

输出:

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

2）执行命令“./node_modules/.bin/ng-xi18n”，它给出以下错误

c:projecttTempPathtrak3pathtrak>./node_modules/.bin/ng-xi18n“TypeError:无法读取object.main(c:projecttTempPathtrak3pathtraknode_modules@angularcompiler-clisrcextract_i18n.js:7:34)中function.extractor.create(c:[e-mail]:69:45)中未定义的属性(c:projectstempPathtrak3Pathtraknode_modules@angularcompiler-clisrcExtract_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module.load(module.js:446:12)在function.module._load(module.js:438:3)在module.runmain

由于这个错误，我无法实现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Package.json文件中的版本问题吗？好心的帮助

谢谢，Sardar Nale

-----修改----------------------------------------

我删除了node_modules文件夹并尝试如下更新package.json，未满足的挂起问题已解决，但在运行时给出了错误

Answer 1

我猜这只是你的角度版本不匹配。对于每个 包，您应该坚持使用相同的版本（除了路由器，在angular 4发布之前，它将高出一个主要版本）。

和你的。。。。

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

。。。看来您在2.4.1的位置至少有 ，可能在2.4.1的位置有 。由于您已经将其他 包设置为2.1.1的固定版本，因此会出现一些冲突。

注意:文档总是假设你是最新的（稳定的）角度版本。

那么如何修复它。。。

您只需添加 &即可安装旧的软件包； 修复了 json ode=""> 中的2.1.1（不要忘记删除这里的插入符号(^)）。然后删除 文件夹并再次运行 。

另一种选择是将您的othercode@angular/code>包也更新到最新的2.4.1版本。在这里，您必须用 中的2.4.1替换您的2.1.1（除了路由器是3.4.1)。然后删除 文件夹并再次运行 。

在这里，你可能会遇到一些其他问题，这取决于你的应用程序。。。您可能需要先检查更改日志。

供参考:当您在项目中安装一个新的 包时，请始终坚持使用当前使用的版本。在您的情况下，要安装特定的版本，应该是（请注意

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

。。。或全部更新到新版本-）
