Fix problem with bcrypt library linkage breaking in dev

[metasoarous]

Had trouble getting the system started with docker-compose with the dev overlay because I kept getting an error like Error: Cannot find module .... bcrypt.

This seemed to have been caused by some build directory corruption, and was fixed by the suggestion here of running npm rebuild. Of course, this had to be done from within the polis-server container, so the trick is to get the system running, then run docker ps to find the process id, then use that in the command docker exec -it xxxxxxxx /bin/sh to get a shell, from which npm rebuild can be executed.

Any additional context which might be relevant?

I've had similar problems with primordials in the past which might have been fixed by doing this.

I wish there was a way to get fresh builds every time (for sure), but this might have to do with the image mapping (as a dev convenience), combined with some failure of npm to do the right thing.

Now seeing this manifest in a slightly different manner with Error: Error loading shared library /app/node_modules/bcrypt/lib/binding/napi-v3/brcypt-lib.node: Exec format error

This time, the npm rebuild trick did not work for the user. After a little research, it seemed like adding node_modules to the server/.dockerignore might fix things, but as it turns out, this is already in our dockerignore 🤔

Very unclear why this issue is manifesting this way, but it only seems to occur when trying to run in development mode, so maybe this has to do with the typescript watch somehow.

In any case, clear now that this is an actual bug (if intermittent) that needs to be solved, not just a transient issue due to old build state on my machine (this new error was reported by a new developer just firing up the project).

This message might be relevant (from the npm build log):

Pre-built binaries not installable for bcrypt@5.0.1 and node@14.14.0 (node-v83 ABI, musl) (falling back to source compile with node-gyp)
