cypress-io / instrument-cra

I have an app that was using this with npm. I switched to pnpm to install packages and now get this error for the same script.

> training-react@0.2.0 start E:\app
> react-scripts -r @cypress/instrument-cra start

E:\app\node_modules\.pnpm\@cypress+instrument-cra@1.4.0\node_modules\@cypress\instrument-cra\index.js:72
require.cache[webpackConfigPath].exports = fakeConfig

I'm getting the same error using "rush" tool.
Any updates on that?

Same issue with yarn and executing inside the cypress node docker

I'm having the same issue with pnpm (trying to switch from npm to pnpm).

I am having the same issue. Any workarounds?

If you are running inside the docker container, check out the node_modules path. My case was webpackConfigPath is different than where the actual node_modules folder is located.

check the require.cache object here

instrument-cra/index.js

Line 72 in 1dda521

require.cache[webpackConfigPath].exports = fakeConfig

to see if there are the /node_modules/react-scripts/config/webpack.config.js property exist

Not working with pnpm
