可能重复this,但详细问题没有显示有问题的特定错误消息,因此它含糊不清且无益.当我在Google中输入错误时,我根本无法找到它,这是因为他的问题在任何地方都没有包含错误.

除非为了清楚起见编辑了其他问题,否则请不要关闭此问题,因为相关错误没有其他结果.

尝试在升级到v5后运行ng服务,但是出现了一些错误.谁知道怎么了？根据package.json,我的@ angular / compiler-cli是5.0.0 …不确定为什么它说5.0.0小于2.3.1.

这是我的升级命令：

npm install @angular/{animations,common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router}@5.0.0

我收到以下错误：

$ng serve
Your global Angular CLI version (1.5.0) is greater than your local
version (1.0.0). The local Angular CLI version is used.

To disable this warning use "ng set --global warnings.versionMismatch=false".
Version of @angular/compiler-cli needs to be 2.3.1 or greater. Current version is "5.0.0".
Error: Version of @angular/compiler-cli needs to be 2.3.1 or greater. Current version is "5.0.0".
