在 dockerizing nestjs 应用程序时出错答案

【问题标题】：Getting an error on dockerising nest.js application在 dockerizing nestjs 应用程序时出错
【发布时间】：2020-06-18 15:42:03
【问题描述】：

我正在开发一个 Nest.js 应用程序，这是我们拥有的 Dockerfile。当我运行它时，我在 docker 中的 npm run build 步骤上遇到错误。这是 package.json 中的构建任务。 "build": "nest build"

sh: nest: not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! atom-qbuilder-api@0.0.1 build: `nest build`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the atom-qbuilder-api@0.0.1 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Dockerfile

标签： docker nestjs

【解决方案1】：

@nestjs/cli（nest 命令的来源）默认位于devDependencies。除非您在package.json 中修改了您的部门，否则运行npm i --production 将不会安装@nestjs/cli，这将导致您当前遇到的错误。您可以使用多阶段 dockerfile 或将 @nestjs/cli 移动到您的 dependencies 而不是 devDeps。
