Could not detect rake tasks (LanguagePack::Helpers::RakeRunner::CannotLoadRakefileError)

[apextemple]

Hi, @indirect, thanks for fixing the issue with s3! I'm currently facing the issue that the rake tasks are not detected. I tried everything on my end to make it work, but couldn't find any solution.

The error appears after all gems are installed, the it suddenly throws an error when it tries to detect the rake tasks. I tried 'bundle exec rake -P' and everything works fine.

I think this is the relevant part of the error:

@nikhilthombare

The latest bundler is 2.0.0.pre.2, but you are currently running 1.15.2.

Make sure to install the right bundler version. You're currently running on 1.15.2

Try
gem uninstall bundler
and deinstall the old versions and then install the new one
gem install bundler -v 2.0.0.pre.2

Probably you'll need to run bundle install

And then make sure your lockfile is correct, everything should work.

I have the same problem. How was this fixed? Any help is appreciated.

[apextemple]

Could possibly send me the error?

Also getting the same error as above. Any help would be appreciated!

What do you get when you run bundler -v?

When I ran it I got:

bundler -v
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.
Bundler version 2.0.1

I then ran bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java which updated the Gemlock file.

This fixed the error and I was able to successfully deploy.

Hey guys i have just found that Bundler version 2.0.1 is conflictive with heroku so using Bundler version 2.0.2 might fix the issue at least that was my case

• gem install bundler -v 2.0.2
• bundle update --bundler
• commit & push Gemfile.lock changes in your repo
• deploy with git push heroku master

that did the trick in my case hope it helps someone else!

Hey guys i have just found that Bundler version 2.0.1 is conflictive with heroku so using Bundler version 2.0.2 might fix the issue at least that was my case

* `gem install bundler -v 2.0.2`

* `bundle update --bundler`

* commit & push `Gemfile.lock` changes in your repo

* deploy with `git push heroku master`

Hey I followed and it even worked without installing bundler -v 2.0.2`, thanks
that did the trick in my case hope it helps someone else!

Closing since it's fixed in bundler 2.0.2 otherwise please let us know
