Can't build media-scanner

[dimitry-ishenko]

Trying to follow build instructions in README.md...

yarn install runs fine:

yarn build give this error:

yarn build-linux-x64 gives this error:

Where is dist/index.js supposed to come from?

[dimitry-ishenko]

npm gives basically the same errors:

root@laptop:/build/media-scanner# npm run build

> scanner@1.3.4 build
> run build:ts && node tools/build.mjs

sh: 1: run: not found
root@laptop:/build/media-scanner#

> node tools/build.mjs linux x64

Building for linux-x64

  /build/media-scanner/dist/index.js

It looks like the build script is just broken, but the build-linux-x64 one is missing a file of some sort?

[dimitry-ishenko]

The Dockerfile script is likewise broken:

I dunno if I am doing something wrong... or this project is just an utterly broken mess... 😠 😠

[nytamin]

There likely is an issue with your local environment, as the builds work fine in the CI env.

I see in your logs that you are using the classic yarn version 1, this might be the issue. Try uninstalling it and install yarn 2+.

If you're still not able to figure out what's wrong with your environment, try replacing the run statements in the scripts in package.json with yarn, that should do the trick for you locally.

[dimitry-ishenko]

Thanks @nytamin. I've no idea how yarn versions work, but here are my versions:

root@laptop:/build/media-scanner# node --version
v18.19.1
root@laptop:/build/media-scanner# npm --version
9.2.0
root@laptop:/build/media-scanner# yarnpkg --version
1.22.19

compared to the versions used in the CI:

My versions are slightly behind, but I don't see yarn 2 anywhere...

[dimitry-ishenko]

Oh, so whatever environment you have doesn't matter since, corepack enable installs yarn 4.0.2... So, let me get this straight:

• In order to install corepack, you need to have npm installed...
• Then, you need to run npm install corepack to install corepack...
• Then, you need to run corepack enable to install yarn...
• The above doesn't actually install new version of yarn, but adds some sort of a hook...
• Then, you need to have an older version of yarn installed...
• Then, you need to run yarn install in order to install new version of yarn...
• And only then, you can run yarn build to build the package

I am sorry, but whoever came up with this mess should be lynched.

[dimitry-ishenko]

But the story doesn't end there. Now I get the same error as with yarn dev:

root@laptop:/build/media-scanner# yarn build
src/util.ts:3:28 - error TS2305: Module '"cheerio"' has no exported member 'Element'.

3 import cheerio, { Cheerio, Element } from 'cheerio'
                             ~~~~~~~


Found 1 error.

Mind blown... 🤯 🤯 🤯

[Julusian]

In order to install corepack, you need to have npm installed...

It used to be that corepack was bundled with node. I didn't think they had changed that, but there has been some recent rumblings that it would be.

Then, you need to have an older version of yarn installed...

No, corepack will fetch whatever version of yarn is needed. It installs a yarn executable which does this and then calls that version.

So the steps (last I checked) are:

• Install node
• Then, you need to run corepack enable to install yarn...
• Then, you need to run yarn install in order to install new version of yarn...
• And only then, you can run yarn build to build the package

But I've probably neglected the docker build, causing some errors there

[Julusian]

Oh that dockerfile is entirely broken. Not been updated to handle that the code is typescript or anything

[dimitry-ishenko]

It used to be that corepack was bundled with node. I didn't think they had changed that, but there has been some recent rumblings that it would be.

Well, neither Debian nor Ubuntu bundle corepack with NodeJS. I guess because it's still considered experimental. There is node-corepack package in Debian unstable/testing and the upcoming Ubuntu version... but that doesn't really help. Debian packages don't usually allow downloading of external dependencies during build process.

[Julusian]

The docker image now builds. I only tested it as far as it complained it couldnt find the config file.

Debian packages don't usually allow downloading of external dependencies during build process.

Surely that means that yarn install is not allowed either? ;)

Tbh I have little interest in supporting whatever version of nodejs ubuntu/debian package. Ensuring this works with the node 12 that is available in ubuntu 22.04 is going to be a painful task, and I don't want to be held back on node 18 either. Doing so means essentially not updating or adding any dependencies, as while they generally follow semver, some don't care if they publish a semver minor/patch version that breaks support for eol nodejs.

This is why for https://github.com/Julusian/CasparCG-ppa/tree/main I simply take the built executables from here. I probably should at least make that use a folder of code rather than the executable, but it works and hasn't bothered me enough to change it

[dimitry-ishenko]

Surely that means that yarn install is not allowed either? ;)

That's right. Debian/Ubuntu provides a lot of node-* packages in their repo and dh-nodejs script which helps pull in needed deps using the package management system... But, I haven't crossed that bridge yet.

@Julusian that's why we should re-write media-scanner using a normal language like C++. IMHO.

[dimitry-ishenko]

Surely that means that yarn install is not allowed either? ;)

FWIW here is an excerpt from the Debian Policy manual, section 4.9:

For packages in the main archive, required targets must not attempt network access, except, via the loopback interface,
to services on the build host that have been started by the build.
