Anyone? 😢

[mbonnin]

Double checking: do you have Kotlin 1.3.70 in your path ?

[mbonnin]

What does env kotlin say?

[fcosta]

Yes!

$ env kotlin
Welcome to Kotlin version 1.3.70 (JRE 1.8.0_232-b09)
Type :help for help, :quit for quit

Sorry for the long delay.
The root problem is this:

error: cannot access script base class 'org.jetbrains.kotlin.mainKts.MainKtsScript'

That means that you have an atypical installation, and kotlin compiler is not able to find kotlin-main-kts.jar, and interprets all scripts as a default ones.
How is the kotlin compiler installed in your system?
And can you have a look at the folder where kotlin-compiler.jar is located?

[fcosta]

I installed with Homebrew

[Jaxon Du]

Any solution?

[Jaxon Du]

I tried out the sample scripts at https://github.com/Kotlin/kotlin-script-examples/blob/master/jvm/main-kts/MainKts.md and encountered similar error. The problem is not homebrew version. I tried remove homebrew kotlin and manually install the release from Github, and it did not work. Then I open up IntelliJ IDEA, and create the script file inside the IDE. And when I go back to run the script inside terminal, it works! So somehow the IDE is able to pull down the dependencies correctly, which the command line “kotlin” is having problem.

[ilya.chernikov]

thanks for the investigation, @Jaxon Du! I'll try to find out what's the root of the problem.

@ilya.chernikov I also noticed setting the env variable KOTLIN_MAIN_KTS_COMPILED_SCRIPTS_CACHE_DIR does not work. I'm on latest macOS.
