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：

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

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": {

答案 0 :(得分：3)
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......
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。
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; - ）
