在 dockerising nest.js 应用程序上出错

Question

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npm run build在 docker的步骤中遇到错误。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.

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