Unable to run theia for the first time

[cortopy]

Description

This is a newcomer here. I really like the Docker version but I'm unable to run from source.

When I try to run the suggested instructions for the browser I get the following error:

Error: Cannot find module '../lib/theia'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15)
    at Function.Module._load (internal/modules/cjs/loader.js:562:25)

error Command failed with exit code 1.

I've looked in the dev-packages and I can see the cli is just an import for ../lib/theia but I just don't know where that lib directory is.

I've also tried to run yarn build in case that directory is generated at build time, but this command also returns an error:

{ Error: Command failed: yarn run build
error An unexpected error occurred: "spawn ENOMEM".

An unexpected error occurred: "spawn ENOMEM".

Maybe you don't have enough memory, try with --max_old_space_size=4096. You could set as env variable for Node.js: export NODE_OPTIONS=--max_old_space_size=4096

I was getting more errors, but all resolved now

Hi, I am also a newcomer...how did you resolved the Error: Cannot find module '../lib/theia'
Getting the same error

[akosyakov]

@rytina Look you are hitting #7974 We will look into resolving it today. You can use latest tag instead as a workaround.
