Trouble "Getting Started" with crra

[Charlie Roth]

So here is a screenshot of the errors that is outputted after only running yarn start:

Being a complete beginner with reason/reason-react, is there anyway I can get some help with solving these errors?

[Mateusz Zatorski]

what version of node are you using?

[Charlie Roth]

8.1.4 @knowbody

[Steve Pikelny]

@knowbody I'm getting the same error.

When I initially run yarn start I get the following webpack error:

ERROR in multi webpack-dev-server/client?http://localhost:8080 webpack/hot/only-dev-server ./lib/js/src/index.js
Module not found: Error: Can't resolve './lib/js/src/index.js' in '/Users/stevepikelny/Desktop/code/test/totally-reasonable'
 @ multi webpack-dev-server/client?http://localhost:8080 webpack/hot/only-dev-server ./lib/js/src/index.js

But I think the failure is missing some clean up.

If I run yarn start a second time, I get the error related to the port being in use.

Here is how line 7 looks like

With node 8 I am getting the same error. But with node 7 there is no error, but I'm not able to connect to the server using localhost:8080.

[Raphael Rafatpanah]

I am using Node v7.9.0 and crra v0.2.3 and am facing the same problems.

Error: listen EADDRINUSE :::8080

Then when running killall -9 node, and re-running yarn start:

ERROR in multi webpack-dev-server/client?http://localhost:8080 webpack/hot/only-dev-server ./lib/js/src/index.js
Module not found: Error: Can't resolve './lib/js/src/index.js' in '/Users/raphael.rafatpanah/Code/reason/create'
 @ multi webpack-dev-server/client?http://localhost:8080 webpack/hot/only-dev-server ./lib/js/src/index.js

And when running yarn build:

File "/Users/raphael.rafatpanah/Code/reason/create/src/app.re", line 7, characters 14-16:
Error: This pattern matches values of type unit
       but a pattern was expected which matches values of type

[Connor Elsea]

Hello! This repo is deprecated in favor of the create-react-app extension we've made, documented here: https://reasonml.github.io/reason-react/gettingStarted.html#getting-started-reason-scripts

I'll close this issue and put up a deprecation warning so that people don't accidentally install this anymore. Sorry for the trouble!
