Steps to reproduce

vue add @vue/cli-plugin-e2e-cypress

What is expected?

@vue/cli-plugin-e2e-cypress should latest version of cypress i.e 5.4.0

What is actually happening?

@vue/cli-plugin-e2e-cypress is still using cypres 3.8

@trungdang194 it seems to me that currently you have to add your version of Cypress separately. The below example might help.

npm install cypress --save-dev

and then add resolutions section to your package.json:

"resolutions": {
    "cypress": "^6.8.0"
  },

The good: The above example will use cypress v6 when cypress commands are run.

The bad: Cypress v3 still gets downloaded since it’s part of @vue/cli-plugin-e2e-cypress, but v6 will be used in the above case as required. Also in our Gitlab CI, “Unzipping Cypress” v6 takes like 3-4 minutes, which is a disaster.

I noticed that @vue/cli-plugin-e2e-cypress v5 will have the updated version of cypress within. I also started a discussion about this here.

This is a known issue for a long time. IMO when using vue-cli you should be able to select manually Cypress version. Also Cypress v4 and later support TypeScript natively. However, even if you select TypeScript in vue-cli, the Cypress project is still generated in Javascript.

I recommend deleting the Cypress plugin and adding Cypress manually. This is very easy to do.

Can you write a small guidance how to run on newest cypress version ?
