Running locally returns 500 error

[magnuswahlstrand]

I have followed the Running locallly guide, and get the server up and running. When I try to access it at localhost:8080 or http://localhost:8080/github.com/kyeett/adventure-island/ I just get a 500 error.

o run -tags "norwfs dev local" main.go                                 1 ↵

Hey I just pushed a v0.0.2 tag of jsgo which fixes a bug in the localfetcher which might resolve this problem... Give it a go and let me know!

[magnuswahlstrand]

Got the same error after running go get -u ... and the other steps, unfortunately

[dave]

Hmm was there anything outputted to the terminal by main.go?

[dave]

... and how about if you just hit http://localhost:8080/ with no path?

[dave]

.. and what happens if you hit http://localhost:8081/ ?

I get the same error. Loading from 8080 is triggering an error when trying to _script.js. 8081 is just a redirect.

Terminal Output:

OK the redirect from http://localhost:8081/ is expected. The root of compile.jsgo.io does a redirect to the Github repo. If you add a path to the URL - e.g. http://localhost:8081/foo.bar/baz it should deliver the page for compiling the foo.bar/baz package.

The 500 error from http://localhost:8080/_script.js is not expected... My next step would be to add a bit more debugging output in the ScriptHandler function - that's the function that should compile the github.com/dave/play GopherJS app and return the javascript... Try adding fmt.Println(err.Error()) before http.Error(w, err.Error(), 500).

I can't reproduce your error so it's tricky to debug... Let me know what you find out!

Looks like that found it

cannot find package "github.com/dave/dropper" in any of:
        /usr/local/go/src/github.com/dave/dropper (from $GOROOT)
        /mnt/c/Users/liamk/Projects/godir/src/github.com/dave/dropper (from $GOPATH)
exit status 1

I probably just needed to have Modules turned on

[dave]

Aah ok you might need to do a go get -u github.com/dave/play - see if that fixes it...

[dave]

Oh, no you'll probably need modules turned off... Jsgo was created before modules and I haven't updated it to support them yet.

[upsampled]

I ran go get github.com/dave/dropper and go get -u github.com/dave/play , then reinitialized (go generate step) and it is running locally now

[dave]

Great! I'll add a note to the instructions about this.
