Fail initialize cask - Could not determine the version of Emacs at emacs

[conao3]

Hi! I interested in this project and use it in Travis CI.

I referenced your .travis.yml and your using gist but my build is failed with ValueError: Could not determine the version of Emacs at emacs.
Do you have any ideas and am I missing something?

  matrix:
    - EMACS_VERSION=26.1-min
    - EMACS_VERSION=26.2-min
    - EMACS_VERSION=emacs-snapshot

    - env: EMACS_VERSION=emacs-snapshot

This happens in my project as well: https://travis-ci.org/Emacs-Kotlin-Mode-Maintainers/kotlin-mode/builds/603296244?utm_medium=notification&utm_source=github_status

Ignore the emacs 24.x builds, those fail for a different reason (but you can see cask is getting past the above error). Emacs 25 works fine, but emacs 26+ fails as above.

This is not an Cask issue: and emacs-26.1-travis has runtime dependency on libgnutls.so.26

Quick fix update to trusty:

dist: trusty

The recommendation by @juergenhoetzel did not work for me.

Anyone else have any ideas on how to make this work?

Finally, I gave up to use prebuild Emacs on TravisCI.
I switched to GitHub Actions, use @purcell 's prebuild Emacs (setup-emacs) and use my setup-cask.
This approach aproved by many packages.

• dash
• php-mode
• helm-swoop
• leaf-keywords

This worked for me:

dist: trusty

language: generic
sudo: false

env:
  matrix:
    - EMACS_VERSION=26.2-min

matrix:
  allow_failures:
    - env: EMACS_VERSION=emacs-snapshot

install:
  - export PATH="/home/travis/.evm/bin:$PATH"
  - export PATH="/home/travis/.cask/bin:$PATH"

  - git clone https://github.com/rejeep/evm.git /home/travis/.evm
  - evm config path /tmp
  - evm install emacs-26.2-travis --use --skip
  - curl -fsSkL https://raw.github.com/cask/cask/master/go | python

script:
  - cask --version
  - $(which emacs) --version
  - EMACS=$(which emacs) make test

@conao3 I agree that using github actions is now a better setup than the somewhat unmaintained evm&cask combo. I'm going to close this but feel free to continue the discussion.
