Had to manually force install on Windows

[pdevito3]

Current behavior

When doing an install for the first time, I followed the instructions here (1. run npm i cypress --save-dev in a react project with node_modules and package.json, 2. run ./node_modules/.bin/cypress open)

I had cypress at that node modules path, but it didn't run the installer when i did the npm install, so i get the below error when trying to open it.

Once I ran npx cypress install --force (didn't work without force), it ran the install and I was able to open it

Debug logs

It looks like this is your first time using Cypress: 7.5.0


Cypress failed to start.

This is usually caused by a missing library or dependency.

The error below should indicate which dependency is missing.

If you are using Docker, we provide containers with all required dependencies installed.

I don't understand why some users run into install issues on Windows and some don't. I've seen some Windows users see this error because their org doesn't allow them to open non code-signed exe files. I suspect there is some kind of Windows network settings that are not allowing Cypress to install. I've never encountered these errors on install or upgrade within Windows.

that could be it for me. this is my corporate comp that i do have pretty good flexibility on privilege wise, but could have some underlying stuff like that in play regardless. let me know if there's something you'd like me to check for this.

regardless, might be worth a note in the docs that calls out if you don't see the install happening after the normal npm install that you might need to manually run the above

Actually, I don't think npm install --force seems relevant in terms of Windows perms. This would just have all the packages re-downloaded and re-installed.

From my understanding, it's forcing redownload of cypress and all child dependencies. So I think there must have been some conflict with the original deps - where it wasn't downloading a child dep originally without this flag.

I'd like to more clearly understand why this is necessary before recommending it as a broad solution in the docs.

I also feel like this error is too generic. I see it often for different reasons that don't ever seem clearly described in this error.

I have currently the same issue.

This issue has not had any activity in 180 days. Cypress evolves quickly and the reported behavior should be tested on the latest version of Cypress to verify the behavior is still occurring. It will be closed in 14 days if no updates are provided.
