我正在使用angular2 .
我使用this project进行启动应用程序 .
要实现多语言支持this documentation
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 npm WARN可选跳过选择依赖：fsevents@^1.0.0（node_modules \ chokidar \ node_modules \ fsevents）：npm WARN notsup SKIPPING OPTIONAL DEPENDENCY：不支持fsevents@1.0.15的平台：want {“os”：“darwin”，“arch”：“any”}（当前：{“os”：“win32”，“arch”：“ x64“}）npm WARN @ angular / core @ 2.1.1需要一个rxjs@5.0.0-beta.12的对等体，但没有安装 . npm WARN @ angular / forms @ 2.2.4需要@ angular / core @ 2.2.4的对等，但没有安装 . npm WARN @ angular / forms @ 2.2.4需要@ angular / common @ 2.2.4的同伴，但没有安装 . npm WARN @ angular / http @ 2.1.1需要一个rxjs@5.0.0-beta.12的对等体，但没有安装 . npm WARN @ angular / router @ 3.1.1需要一个rxjs@5.0.0-beta.12的对等体，但没有安装 . npm WARN codelyzer@1.0.0-beta.4需要tslint@^3.9.0的对等方，但没有安装 . npm WARN codelyzer@1.0.0-beta.4需要@ angular / compiler @ ~2.2.0的对等体，但没有安装 . npm WARN codelyzer@1.0.0-beta.4需要@ angular / core @~2.2.0的对等体，但没有安装 . npm WARN tslint-loader@2.1.5需要tslint@^3.0.0的对等体，但没有安装 . npm WARN @ angular / compiler-cli @ 2.4.1需要@ angular / compiler @ 2.4.1的对等，但没有安装 . npm WARN @ angular / compiler-cli @ 2.4.1需要@ angular / core @ 2.4.1的对等体，但没有安装 .
2）执行命令“./node_modules/.bin/ng-xi18n”它给出了以下错误
C：\ Projects \ temp \ PathTrak3 \ PathTrak>“./ node_modules / .bin / ng-xi18n”TypeError：无法在Function.Extractor.create中读取未定义的属性'create'（C：\ Projects \ temp \ PathTrak3 \提取时的PathTrak \ node_modules \ @angular \ compiler-cli \ src \ extractor .js：69：45）（C：\ Projects \ temp \ PathTrak3 \ PathTrak \ node_modules \ @angular \ compiler-cli \ src \ extract_i18n.js： 7:34）在Object的Object.main（C：\ Projects \ temp \ PathTrak3 \ PathTrak \ node_modules \ @angular \ tsc-wrapped \ src \ main.js：47：16） . 位于Object.Module._extensions的Module._compile（module.js：570：32）处的（C：\ Projects \ temp \ PathTrak3 \ PathTrak \ node_modules \ @angular \ compiler-cli \ src \ extract_i18n.js：14：9）在函数.Module._load（module.js：438：3）的tryModuleLoad（module.js：446：12）的Module.load（module.js：487：32）中的..js（module.js：579：10） ）在Module.runMain（module.js：604：10）提取失败
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/platform-server": "^2.1.1",
"@angular/router": "3.1.1",
"@angularclass/conventions-loader": "^1.0.2",
"@angularclass/hmr": "~1.2.0",

"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？请帮助
谢谢，Sardar Nale

我删除了node_modules文件夹，并尝试更新package.json，如下所示，UNMET dpendancy问题已解决，但在运行时出现错误，因为 Error

我想这只是你的 angular versions 中的一个不匹配 . 你应该为每个
@angular软件包坚持使用相同的版本（路由器除外，它将是1个主要版本，直到角度4被释放） .跟你的...
......似乎你至少在_ 4.1 得到
@angular/compiler-cli，可能在2.4.1得到@angular/platform-server. 由于您已将 other@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：文档将始终假定您使用的是最新（稳定）角度版本 .
那么如何解决它......
1.安装旧包
您可以通过在
package.json中将@angular/compiler-cli＆@angular/platform-server添加到固定 2.1.1 来安装旧软件包（请不要忘记在此处删除插入符号（^）） . 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，您必须将 2.1.1 替换为package.json中的 2.4.1 （除了将是 3.4.1 的路由器） . 然后删除node_modules文件夹并再次运行npm install.在这里，您可能会遇到一些其他问题，具体取决于您的应用...您可能需要首先检查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 . 要在您的情况下安装特定版本，请注意（注意@2.1.1）：...或更新所有新版本;-)
