Problem running website at the uni

[javier-romero]

Hi @rkaminsk,

I was trying to follow the instructions of the README to launch locally the website and I got this error:

bundle install --path .bundle
[DEPRECATED] The `--path` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set path '.bundle'`, and stop using this flag
Warning: the running version of Bundler (2.1.4) is older than the version that created the lockfile (2.3.7). We suggest you to upgrade to the version that created the lockfile by running `gem install bundler:2.3.7`.
The dependency tzinfo (~> 1.2) will be unused by any of the platforms Bundler is installing for. Bundler is installing for x86_64-linux, ruby but the dependency is only for x86-mingw32, x64-mingw32, x86-mswin32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x64-mingw32 x86-mswin32 java`.

public_suffix-5.0.3 requires ruby version >= 2.6, which is incompatible with the current version, ruby 2.5.5p157

It says public_suffix-5.0.3 requires ruby version >= 2.6 but when I try to install some higher version of ruby I get this error:

Your installed version is: 2.28

so I get that rb-bundler requires a version of ruby under 2.6

rb-bundler -> ruby[version='>=2.5.5,<2.6.0a0|>=2.5.7,<2.6.0a0']

[rkaminsk]

rb-bundler is no longer required for ruby 2.6 and later. You can simply remove it from the package list.
