NODEJS v12.13.0 on IBM i Fails With "Error: setRawMode EINVAL"

[Marlon Berryman]

Hello All,

‌

I am attempting to run NODEJS (interactively, in QSH/QP2TERM) on IBM i (V7R2).

When i execute “node” (to access REPL), node terminates with the following error:

‌

node -v
v12.13.0
\$

node

Type ".help" for more information.

throw er; // Unhandled 'error' event

** I get this same error with Node 10 (v10.16.3 ) as well. Any assistance/direction will be greatly appreciated!

**My apologies if i missed where this issue has already been issued/resolved by the community.

It seems that running the REPL in a 5250 session has not worked since Node 10. Even in Node 8, it’s a painful experience:

‌

 > /QOpenSys/pkgs/lib/nodejs8/bin/node
    [1G [0J>  [3G
 > console.log('help')
   console.log('help')
   help
    [90mundefined [39m
    [1G [0J>  [3G

I’d recommended using SSH instead of 5250.

Hi Kevin,

Thanks for your quick response. I will try from an SSH session as well and let you know if i encounter any issues. Also, i tried your “PASE_STDIO_ISATTY=N“ tip (from Issue #80) and so far REPL appears to be working (with v12.13.0.)
