Installation fails on Ubuntu 22.04.2 LTS

[eguvep]

Thanks for this revolutionary peace of software – I love it!

Unfortunately, some students still want to use a pdf for taking notes, because they are used to do it that way. So I tried to install the exporter with:

sudo npm install -g --verbose https://github.com/liaScript/LiaScript-Exporter

Unfortunately, this fails with:

npm ERR! code 128
npm ERR! An unknown git error occurred
npm ERR! command git --no-replace-objects ls-remote ssh://git@github.com/liaScript/LiaScript-Exporter.git
npm ERR! git@github.com: Permission denied (publickey).
npm ERR! fatal: Konnte nicht vom Remote-Repository lesen.

npm verb exit 128

Thanks, Peter ...

you can try this one

sudo npm install -g --verbose @liascript/exporter

this will install the exporter from npm. We have to check why the other option does not work anymore ...

I hope this works for you?

Best, André

Thanks a lot for the quick reply! The suggested option is doing a lot of stuff, but finally also quitting with some errors. Find the log file here: npm_lia_exp.log -- Peter

Hi, looks like puppeteer could not be installed, did you use sudo npm ... to install or without sudo?

What node and npm version are you using?

npm -v

[eguvep]

Yes, I tried sudo npm install -g --verbose @liascript/exporter Get the same error on two different computers (see below). I am using node v12.22.9 and npm v8.5.1

Without sudo I get:

Can you try to upgrade your node version with n:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

and then retry?

[eguvep]

I did that, and the installation worked fine. I still had to do:

sudo chmod +x /usr/local/lib/node_modules/@liascript/exporter/dist/index.js
cd ~/.cache/puppeteer
npx @puppeteer/browsers install chrome@127.0.6533.88

to downgrade chrome to the desired version. Then

liaex -i EnergiespeicherVEP_A.md --format pdf --output Energiespeicher.pdf

was running some time and asked me to be patient, finally produced a pdf ... that was just a blanc page, though :-(

[andre-dietrich]

what do you see, when you run:

liaex -i EnergiespeicherVEP_A.md --format pdf --output Energiespeicher --pdf-preview

this should open the browser and display the content ...

[eguvep]

I see a blank page.

[andre-dietrich]

That was a hard one .... the parcel bundler we use applied a regular expression to check for the origin of an URL

/(https?|file|ftp|(chrome|moz|safari-web)-extension):\/\/[^\/]+)/

this works well for file://foo.bar, but not for the root file:/// ... that is why nothing was loaded or executed at all ...

I changed this manually at the moment and updated it ... This should work now.

Puppeteer has also been update to the latest version ... which should not require a manual installation ... next to some minor fixes ....

if you are using your courses on github, you could try to run the following workflow:

https://github.com/LiaScript/docs/blob/master/.github/workflows/deploy.yaml

I added this for testing purposes ... the output is stored as a release in the project:

https://github.com/LiaScript/docs/releases/tag/latest

... Hope it works for you too ... now ...

Thanks a lot for that very quick fix and for the CI workflow! Export is working perfectly now. LiaScript is - by far - the most efficient tool for creating contemporary learning material, I know!
