NestJS cli 错误：无法解析集合“@nestjs/schematics”

Question

我正在尝试学习 NestJS，只是按照简单的教程来创建 Nestjs 应用程序。

执行 cli 命令时出现以下错误nest new test-project

NestJS cli 版本：7.1.5 NodeJS 版本：v10.18.1

错误：

Error: Collection "@nestjs/schematics" cannot be resolved.

Answer 1

为了继续使用纱线，这对我有用 https://github.com/nestjs/nest-cli/issues/613#issuecomment-602235328

Answer 2

我有同样的问题。同一条error消息。我用纱线安装了 Nest，所以我使用下面的命令来添加（安装）示意图：

yarn global add @nestjs/schematics

如果你使用 npm 使用这个

npm i -g @nestjs/schematics
