NestJS cli错误：无法解析集合“ @ nestjs / schematics”
我正在尝试学习NestJS，并按照简单的教程来创建nestjs应用。
执行cli命令时出现以下错误嵌套新测试项目
NestJS cli版本：7.1.5NodeJS版本：v10.18.1
错误：
Error: Collection "@nestjs/schematics" cannot be resolved.

无法执行命令：“ /Users/tsuthar/.config/yarn/global/node_modules/@nestjs/cli/node_modules/.bin/schematics” @ nestjs / schematics：application --name = nestjs-task-management- -directory =未定义--no-dry-run --no-skip-git --package-manager =未定义--language =“ ts” --collection =“ @ nestjs / schematics”
回答如下：最初，我在NestJS cli中添加了yarn，它给出了以上错误。从纱中移除NestJS cli和Npm后，该问题就会得到解决。
