Installing OMP from github


I am trying to install the OMP main branch to try out version 3.4. I am doing this as described on
Composer reports a few warnings, but ‘npm build’ returns an error:

> OMP@3.3.0 build
> vue-cli-service build --no-clean

Browserslist: caniuse-lite is outdated. Please run:
  npx browserslist@latest --update-db
  Why you should do it regularly:

⠹  Building for production.../srv/www/omp00/htdocs/node_modules/loader-runner/lib/LoaderRunner.js:106
			throw new Error("callback(): The callback was already called.");

Error: callback(): The callback was already called.
    at context.callback (/srv/www/omp00/htdocs/node_modules/loader-runner/lib/LoaderRunner.js:106:10)
    at /srv/www/omp00/htdocs/node_modules/css-loader/dist/index.js:141:5

Node.js v18.12.1

I also tried ‘tools/ 3.4 main’, the same thing happens.
‘npm audit fix’ doesn’t help either.
Shouldn’t the first installation just work like that? What could be a possible error?
I’m new to composer and node/npm, any help would be appreciated.

Hi @ohilbig01,

You’re running into a change between Node 16 and Node 17 that affects some of our dependencies. See for details. You can either downgrade to Node 16, or use the following command instead:

NODE_OPTIONS=--openssl-legacy-provider npm run build

Hi @asmecher ,

thank you, that helped. I used node v16.18.1 and ‘npm run build’ runs through without error, only with deprecation notes and warnings.

Hi @asmecher,

when I try to upgrade an existing OMP to 3.4 i get the following error:

2022-12-09 11:07:45 [Nulling non-existent source_submission_file_id 1660 in submission_files.]

Hi @ohilbig01,

Version 3.4 had not yet been released and will be unstable. Please stick with 3.3 unless you are prepared to deal with bugs and instability.

Hi @asmecher ,
yes, I am aware of that. I thought it would be useful to report this error.

Hi @ohilbig01,

Are you sure you’re using an up-to-date checkout? Orphaned data in stage_assignments referring to non-existent user_group_id entries in user_groups should be cleaned up during the preflight check migration here.

Hi @asmecher,

what I do is this:

git clone
git submodule update --init --recursive


composer --working-dir=lib/pkp install
composer --working-dir=plugins/paymethod/paypal install

nvm use v16.18.1
npm install
npm audit fix
npm run build

I assume the installation is then up-to-date.
When i do a completely new installation, it works like this.

But when I use an existing database (version OMP and the associated files folder and try to update:

php tools/upgrade.php upgrade

then I get the error described above.

Hi @ohilbig01,

Thanks, I identified a small typo in the preflight check data cleanup that prevented it from catching and cleaning up some inconsistent data in your database:
