Incorrect version of jest trying to run jest - jestjs

Question

I have jest tests in my angular project.
I have a package.json file specifying the version of jest I would like to use to run the test. The file includes:
"#types/jest": "^24.0.18",
"jest": "^24.9.0",
"jest-preset-angular": "^7.1.1",
The jest config also includes:
"setupFilesAfterEnv": [
"<rootDir>/setup-jest.ts"
],
This is where the issue occurs. When trying to run jest, I get the following message:
● Validation Warning:
Unknown option "setupFilesAfterEnv" with value ["<rootDir>/setup-jest.ts"] was found.
This is probably a typing mistake. Fixing it will remove this message.
Configuration Documentation:
https://jestjs.io/docs/configuration.html
I had a look at jest -h and found a flag which gives me the setup of the jest environment.
jest --showConfig
This however shows that I am running jest on version
"version": "23.6.0"
So my question lies here. How come after I do an npm i, the jest version trying to run the tests is different / old.
I tried installing jest-cli with the -g flag and the save-dev flag.
Also trying to run tests in VS Code, if thats any help.
Please help.
Thank you in advance.

I had the same issue, after a long search I've tried this:
type jest
Which gave me the location:
/usr/local/bin/jest
Renaming this file (or deleting it), solved the problem (note that now running jest will give command not found).
