Windows 10 repl doesn't connect to the browser

ronnac commented 2 years ago

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".

The browser automatically opens, but the green "connected" logo doesn't appear.

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 Githubissues.

Githubissues is a development platform for aggregating issues.
