typeorm is not being installed, and keeps making npm error-CodePudding

I am working with a teammate whose environment is OSX while mine is Windows. and we all have same version of node, npm, nestJS:

node version: 18.5.0
npm version: 8.12.1
nestjs version: 9.1.8.

and when I try to install the dependency it keeps getting an error. and the message is like this:

npm ERR! code ERESOLVE<br>
npm ERR! ERESOLVE unable to resolve dependency tree<br>
npm ERR!<br>
npm ERR! While resolving: projectname<br>

npm ERR! Found: [email protected]<br>

npm ERR! to accept an incorrect (and potentially broken) dependency resolution.<be>

when I tried to install typeorm 0.3.0 it also made another error:

npm ERR! code ERESOLVE<br>
npm ERR! ERESOLVE unable to resolve dependency tree<br>

npm ERR! While resolving: projectname<br>

and when I tried to install with npm install --legacy-peer-deps I got a proxy error and I never use proxy. I don't know what is wrong.

CodePudding user response：

You have typeorm 0.2.45 installed when @nestjs/typeorm requires that you use typeorm 0.3.0 or greater. Install the newer version of TypeORM and migrate as necessary as there are breaking changes

CodePudding user response：

Since you're working in dev environment, devDependencies is also installed and makes the conflicts.

To fix this, you need to update @nestjs/cli, @nestjs/schematics and @nestjs/testing to 9.x.x.
