Template generation failed

[aantron]

I'm currently hitting the error below. I first reached this a few days ago, and I waited for the dream-livereload release in case that was the cause. However, this is still occurring after opam update and confirming that opam knows about dream-livereload with opam list.

opam install --deps-only --with-test --with-doc -y .

Thanks @aantron! I am not sure that's the root cause, but I just removed the pins in master. Would you mind trying the generation again?

I now get to a second install (with alcotest, etc.), but afterwards:

Could it be that you're running an "old" version of NodeJS? Tailwind requires Node 12.13 or higher (https://tailwindcss.com/docs/upgrading-to-v2#upgrade-to-node-js-12-13-or-higher)

If this is the issue, I'll add a requirement section in the README, alongside the other suggestions laid down in #5

[tmattio]

Also, the default choices shouldn't fail with this error, as they don't include TailwindCSS. Can you confirm that you explicitly chose to generate the TailwindCSS setup?

Yes, I chose all options to exercise everything.

I have Node 10.19.0 installed. Could you add the requirement, together with a link to instructions somewhere that show how to upgrade Node? I am using Node from Ubuntu 20.04, so this is a pretty aggressive constraint.

[tmattio]

I've added some instructions in the README, alongside with a recommendation to use nvm to manage other versions of Node.

Here are the commands to install it:

# Install NVM
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
# Reload bash
source ~/.bashrc
# Install an NPM version, 14 is the latest LTS
nvm install 14
# Use the version in your current prompt
nvm use 14

[aantron]

These instructions don't work for fish, see nvm-sh/nvm#303. Looking for good workarounds.

[tmattio]

Arg.. I this case maybe the best method for you would be to upgrade your system node's version?

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs

Template generation has now succeeded, thanks!
