奇怪的错误'npm WARN express-validation@1.0.2需要joi @ *的同行但是没有安装......？

Question

'npm WARN express-validation@1.0.2 requires a peer of joi@* but none is installed. You must install peer dependencies yourself.'是什么意思？我该如何解决？

我跑的时候：

npm install express-validation --save 

我明白了：

npm WARN express-validation@1.0.2 requires a peer of joi@* but none is installed. You must install peer dependencies yourself.

然后我跑：

npm install -g npm-install-peers

然后：

npm-install-peers

然后我得到：

This package doesn't seem to have any peerDependencies

然后我跑：

npm install express-validation --save 

我明白了：

npm WARN express-validation@1.0.2 requires a peer of joi@* but none is installed. You must install peer dependencies yourself.

Answer 1

您可以使用npm install joi --save

自行安装

Answer 2

程序包名称错误。如果您要验证应用程序中的数据，则应考虑开始寻找express-validator。

快速验证需要喜悦，我不知道两者的含义。
