Examples do not run from a fresh repo clone when following documented steps

[warrenkc]

I am in Ubuntu trying to get the example to work for: https://github.com/transloadit/uppy/tree/master/examples/node-xhr
When I run npm run build I get an error. I recorded the steps so you can see in a video:

Thank you!

Sorry, the instructions are wrong 🙈 they were copied from a different example but the node-xhr one doesn't have a build script, only npm start.

Some of the examples are a bit broken after a change to our build setup a few months ago. I'll push a fix and update the instructions. Thanks for filing this issue!

This isn't ideal but for now, it works if you go into the repository root, and run this from there:

npm run example "example-name"
# eg. npm run example node-xhr

ideally the examples would be fully standalone, so hopefully we'll have time to address that in the future—this workaround should do the trick in the mean time though.

Thank you!

If I do that then I see this error below. Here is a video showing the issue:

did you do `npm install` in the root directory of the repository first?

Yes. Thank you. I really appreciate your help. I recorded the steps here: https://youtu.be/cuVWq-fxOiM 1: git clone https://github.com/transloadit/uppy.git 2: cd uppy 3: npm install 4: npm run example node-xhr Error:

Ah. so you also have to do npm run build once in the repository root, and then the npm run example thing :D Reopening until I have time to fix the documentation again. Thanks for sharing all these error details 👍

Thank you. I really appreciate it.
