7693 :: globalThis is not defined although node version is v14.4.0

• lotib48819 (orginal) [2021-03-23T23:00:18+01:00] view original

  nim js -d:nodejs -r main.nim

  I get this error message

  
  ReferenceError: globalThis is not defined
  Run

  If you experience errors saying that globalThis is not defined, be sure to run a recent version of Node.js (at least 12.0).

  node -v v14.4.0

  Any ideas?

  Also, will this work in Browser because I see many

  var F={procname:"module macros",prev:framePtr,filename:"/.......path...../.choosenim/toolchains/nim-1.4.4/lib/core/macros.nim",line:0}; Definitely this thing won't work in Browser.

  The "var F" thing has nothing to do with the browser, it's the stack trace entries, they work fine in the browser as well as in Node.

  noted. I also see that in Browser it opens with no error. But echo are muted probably i need to use console.log somehow. But in node js i get that error message.

  @lotib48819 I can't reproduce your issue, please provide more info:

  • nim -v
  • cat main.nim (minimize it first)
  • which OS, etc
  • does the generated code (without -d:nodejs) work in browser
  • node -v (you already did, but double check)
  • try also running node main.js directly with main.js
  • and most importantly, try running this:

  
  node -e 'console.log(globalThis)'
  Run

  interesting. running node main.js it works. Maybe by default it is using a wrong node version. I have nvm and I do have multiple node versions installed including v14, v12, v9 and v8.

  ok; so next step is figure out if it's a user error, or if findNodeJs is buggy, or if findExe is buggy (findExe has many bugs, but maybe this isn't related)

  proc findNodeJs*(): string {.inline.} =
    ## Find NodeJS executable and return it as a string.
    result = findExe("nodejs")
    if result == "":
      result = findExe("node")
  Run

  what is: node -v nodejs -v

  ok. I see I have two installed on my machine...

  when I type

  $ node -v 14.4.0

  $ nodejs -v v10.19.0

  I remember i installed nodejs only though nvm but it looks i have two nodejs now on Ubuntu
