NestJS cli error: Collection "@nestjs/schematics" cannot be resolved

I had the same problem. same error message. I installed nest with yarn so I use command bellow to add(install) shematics:

yarn global add @nestjs/schematics

If you use npm use this

npm i -g @nestjs/schematics

What worked for me was 2 lines of code -

yarn add @nestjs/schematics

nest new your-project-name

Initially, I added NestJS cli with yarn and it gave the above error. The issue gets fixed as soon as I've installed NestJS cli with Npm after removing it from yarn.

I faced this issure recently and none of the suggested issues worked for me. I tried using npm to install @nestjs/cli and also tried to remove @nestjs/cli and reinstall using yarn global add @nestjs/schematics. Finally a hit and trial that did work for me to run the following command using only and only npm

npm i -g @nestjs/schematics

After this when I tried to create my project using nest new cli command, it worked like a charm. After that you're free to choose and use npm or yarn as per your convenience.

I got the same error when creating a new nestJS project with yarn. What worked for me is doing the following:

1. Clean yarn cache yarn cache clean
2. Remove nest cli yarn global remove @nestjs/cli
3. Reinstall nest cli yarn global add @nestjs/cli
4. Create new project nest new project-name
5. Choose yarn when given an option to choose package manager

As @Abderrahmane TAHRI JOUTI mentioned I followed the link and the above solution worked for me.

I was getting the same error for mine but i was using npm instead of yarn i just updated my node version cause Nestjs uses node version of 12 and above

I just upgraded @nestjs/cli and @nestjs/schematics to the latest version which is :

• npm install @nestjs/[email protected]
• npm install @nestjs/[email protected]

and it worked for me

If you have the following problem

> yarn global add @nestjs/schematics
yarn global v1.22.21

info Visit https://yarnpkg.com/en/docs/cli/global for documentation about this command.

Try to install the same version of @nestjs/cli as the @nestjs/schematics.

I install cli using yarn global add @nestjs/[email protected] so I have to install schematics using yarn global add @nestjs/[email protected]

Install this NPM package works for me,

apollo-server-core: 3.7.0
