Ok, I've got a complicated project here to run
npm install on. Let's see if it works.
Ok, so I've got my big project on the Raspberry Pi and NPM install seems to have worked despite throwing a bunch of errors. But now I've got
There is a suggested way forward, let's try it.
I'm going to add this as a command to my
"start:heavy": "NODE_OPTIONS=--max-old-space-size=16384 npm run start",
Ok, let's give that a try.
Nope, still maxing out. In fact, now it does so immediately. Oh, I see. I've made the allowed use of RAM more than the 8gigs in my Raspberry Pi 4.
Hmmm, still getting
This seems to be a memory issue. I think I can increase the memory fast by using a USB key as swap space? Let's try that.
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 119.2G 0 disk
├─sda1 8:1 1 200M 0 part
└─sda2 8:2 1 119G 0 part /media/zs/BigStick

Ok, I've reformatted my BigStick using the instructions at addictive tips. It worked pretty well so far, but I did have to change the type to Linux Swap which is noted as 82 instead of 83 here.
I rebooted and it looks like, by using
free -m I can see I've added about 2 gigs of swap, not the whole stick. Why is that the case?
total used free shared buff/cache available
Mem: 7898 244 7160 35 493 7393
Swap: 2047 0 2047
It looks like that's the max using the tools I used. But lets try leaving it here and rerunning my commands.
Well, it definitely used the swap space and I don't think I ever saw it run out of Memory, but it still failed. New error this time though! Let's reproduce here in full:
