**installing 'cairo-devel' native package... failed**

[slashTPA]

Hi there,

while install via

$ bundle install

on RHEL 8.2 I run into the issue:

Installing cairo 1.16.4 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

current directory: /tmp/bundler20200518-80090-11x4alwcairo-1.16.4/gems/cairo-1.16.4/ext/cairo

Without going deeper into it - was anyone successful to install on RHEL 8.2 ? There is no such repo like 'PowerTools' available - and that can be seen as well in the log:

Any hints?

It looks like it's trying to do some operations as root using sudo while installing 'cairo-devel' and that fails. I've never tried running it with RHEL, as so far I always used Docker to deploy it and did the development on either Debian or Arch machines.

well yes, these PowerTools do not exist in RHEL8.2.
Anyway, as well the docker version is not that straight forward on RHEL due to podman not supporting dns resolution between the containers... and what ever in addition, that keeps me still blocking from accessing localhost:3000.

I suggest to close this here for the moment (as I switched to Ubuntu). If time allows I'll lock into the RHEL implementation some when...
