I have a pretty small typescript app (few files). Everything works and compiles locally. However, whenever I try to do it on my droplet, the tsc
script hangs forever.
I ran the build with --verbose
flag and here’s the output. Does anyone know why the tsc
command hang forever?
root@jcm-v2:/var/www/html/jcm-api-v2# tsc --verbose
error TS5093: Compiler option '--verbose' may only be used with '--build'.

Hi there,
What version of
tsc
are you using?I’ve seen a similar problem in the past as described here:
The problem was sorted out after an upgrade from v4.4 to v4.6.
EDIT:
It turned out that it was a memory problem, adding more memory or a swap file fixed the problem. This was figured out by the following steps:
Open two terminal windows and in the first one run the
htop
command and monitor your server resource utilization, in the second one run thetsc
command.In case that you are running low on memory, I would recommend adding a swap file so that you could have some extra buffer:
