问题描述

我正在尝试创建一个 Nest js 应用程序，但是当我按照他们网站上的步骤操作时，我得到的第一个错误是找不到 ts-node".所以，我安装了那个.我还需要安装几个 typscript 模块(我相信是 typscript 和 tsconfig-paths)，当我清除这些错误并运行 npm run start 时，我收到了找不到节点模块 @nestjs/core"的提示.

I'm trying to create a Nest js application, but when I follow the steps on their website, the first error I get is 'cannot find ts-node'. So, I installed that. There were a couple more typscript modules I needed to install (typscript and tsconfig-paths I believe) and when I cleared those errors up and run npm run start I got a 'Cannot find node module @nestjs/core'.

一旦使用 typescript，就必须安装它，以便能够使用 tsc 命令，该命令将转译您的代码到 javascript.

当您想即时处理转译时，您还需要安装 ts-node.这就是您需要它的原因.
