Windows 10 repl doesn't connect to the browser #305

I am trying to follow the tutorial and don't get the prompt when running the figwheel-main repl.
A) with leiningen:
lein trampoline run -m figwheel.main
B) without leiningen
clj -m figwheel.main
I get the same output:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

This is the output of the browser console:

Part of the problem seems to come from the mix use of backslashes instead of forward slashes in the script paths.

I use git-sdk-64 as Linux replacement / bash environment.
Sidenote: I am able to run a shadow-cljs hello-world with a cljs-repl in that environment.

Seems to be linked to this issue.

I haven't been able to set figwheel up on my Windows 10 machine so I can't say for sure, but I strongly suspect you are on the right lines that it is related to the forward-slash / backslash difference between Windows and *nix.

If you run the following you should see the full config for the dev build which figwheel uses:

lein trampoline run -m figwheel.main -pc -b dev

where -pc is short for --print-config, and I assume your build is defined in dev.cljs.edn.

This gives some very useful information, and you should check the values of the keys :output-to and :output-dir.

The strange thing about what you have posted is the target\public\ appearing in the <script> elements: this shouldn't happen. You could for example try to manually set these two keys in your dev.cljs.edn, to e.g. as follows:

{,,,
:output-dir "target\public\cljs-out"
:output-to "target\public\cljs-out\dev-main.js"
},,,

(or whatever you compiled .js file should be called, which is what the index.html is expecting.)

This may help, or perhaps provide some clue, but unless I have the environment in front of me it's very difficult to debug.
