我有一个angular2项目通过CLI创建和我的package.json看起来像以下：角2只未满足的同行依赖

您需要更新'角到版本4' – Aravind

看起来既'NG2-tour'和'@ NG-bootsrap'期待角^ 4.0.3。您的选择是将这些软件包回滚到较旧的软件包或升级您的核心'@ angular'软件包以匹配依赖项。 –

@Aravind升级到angular4 wouldn'r会破坏什么？ – Nitish

未满足PEER相关性错误。仔细检查警告并使用正确版本的依赖关系更新package.json文件。

然后运行

rm -rf node_modules/ 
npm cache clean 
npm install

这将正确地安装所有需要的依赖。
