Compile Exception: No such namespace: react

After clj -A:dev
I got error:

I checked out file cljs-temp/js-environment.log.

I checked out the error source file reagent/core.cljs. I found react dependency in POM file. Then I try to install it manually.

I try to install react with command clj -Sdeps '{:deps {cljsjs/react {:mvn/version "16.9.0-0"}}}' successfully.

Then I restart clj -A:dev. Still raise up this error.

[stardiviner]

Problem solved, I manually added react and react-dom dependencies into deps.edn fixed this error. Hope this can be added to electron-app template in future.

[stardiviner]

Now the deps.edn is:

:deps    {org.clojure/clojure             {:mvn/version "1.10.1"}
           org.clojure/clojurescript       {:mvn/version "1.10.597"}

           reagent                         {:mvn/version "0.9.0-rc3" :exclusions [cljsjs/react cljsjs/react-dom]}

           cljsjs/react-dom                {:mvn/version "16.11.0-0"}}

[paulbutcher]

You really should not need to do this - react and react-dom are both installed as Node dependencies (see https://github.com/paulbutcher/electron-app/blob/master/resources/clj/new/electron_app/package.json#L15)

Are you quite sure that you've run npm install as described in the README?

[paulbutcher]

I am concerned that the issues that you describe in #2 suggest that there is something odd about your configuration of npm. Are react and react-dom in node_modules? If not, this is your problem and the solution is to fix whatever's wrong with npm on your system.

[stardiviner]

I only have this config in ~/.npmrc
