Rails: You have already activated rake 10.3.1, but your Gemfile requires rake 10.2.2 (Gem::LoadError)

Question

Here is my error:

Gem::LoadError: You have already activated rake 10.3.1, but your Gemfile requires rake 10.2.2. Prepending `bundle exec` to your command may solve this.

I can't run any rake tasks and this seems to be the root of all my other problems. It wasn't like this a couple days ago when I was running rake commands. Can anyone explain what's going on here and how to get my app back on track? I've hit a wall. Also, bundle exec doesn't fix the root of the problem for me. I never had to do that in the past and it's still not working now.

How did you use bundle exec ? You should run rake task like this: `bundle exec rake namespace:task_name` — Santhosh, Apr 25 '14 at 08:10
That is a different issue. This might help https://github.com/rails/rails/issues/2991 — Santhosh, Apr 25 '14 at 08:13
I've already looked at that link and it provides no solution. — Aaron, Apr 25 '14 at 08:15
`bundle update` actually did more harm than good. It reverted a lot of gem dependencies to very early versions. — Aaron, Apr 25 '14 at 08:43

EDIT 2: You should look at bundle update and change your workflow a little. Refer to this question for further assistance.

Original answer

This is a simple issue which happens when your gemset has a rake version that is newer than the version number your Gemfile.lock mentions.

As is mentioned in the error message, you can use bundle exec to get things working.

My solution in such cases is to just remove Gemfile.lock if I am not too worried other gem versions and their endless dependencies. Otherwise, you can try just removing the one line in Gemfile.lock which talks about the version of rake. run bundle install and the world should be a happy place again. (edit 2: Run bundle update --source instead of this. Don't do this.)

PS: Try using gemsets and organising your gems with rvm for different projects.

Edit

I prefer using rbenv now for managing installations and all gems for a project reside in vendor/bundle using bundle install --path option. Later scope every gem command with bundle exec.

Hence, rails s becomes bundle exec rails s. A little more typing is, in my opinion, better if it means that things will remain clean and conflicts such as this one don't happen.

where could i see the _version number of_ `Gemfile.lock`. can i ? – Gupta Feb 18 '15 at 06:34
@Vinay: There is no version number of `Gemfile.lock` as such. You should look in the file `$PROJ_ROOT/Gemfile.lock`. Search for text `rake`. Somewhere there should be a line which mentions a version number. That should be your clue as to what to do next. – manu29.d Feb 18 '15 at 08:05

Downvoting. You shouldn't break Bundler by removing or altering `Gemfile.lock`. Instead, use `bundle update` or something. – Marnen Laibow-Koser Feb 26 '15 at 22:54

@MarnenLaibow-Koser I agree that this is a "bad hack" per say but the situation here says that you have two versions of rake installed in the same bundle. So, you might have done something wrong like maybe, not separating out your bundles properly as per projects and the dependencies of 2 of them clashed. However, I would love to know another solution. Please provide a link if you find one. – manu29.d Feb 27 '15 at 09:23

@manu29.d I haven't figured out a better solution than `bundle update` either, but I wouldn't ever even consider a bad hack like this. – Marnen Laibow-Koser Mar 02 '15 at 02:02
In my particular case, that wasn't an option, since a `bundle update` would mean that a lot of my gems would update and some of them didn't have bac kwards compatibility with others that I was using. Plus the code would also break and certain points. Hence, this solution in my case was what I could come up with – manu29.d Mar 02 '15 at 10:11
@manu29.d That shouldn't be an obstacle to `bundle update`: just specify the appropriate versions in the `Gemfile`. – Marnen Laibow-Koser Apr 08 '15 at 17:32

This does work to remove the need to prepend bundle exec, however, as a word of warning as in my case, all the updates broke other issues I did not want to deal with so I `git checkout --Gemfile.lock` to go back and just live with the rake version discrepancy. – iamse7en Oct 29 '16 at 01:26

You can use rubygems-bundler to solve this. Run the following commands:

$ gem install rubygems-bundler

$ gem regenerate_binstubs

Then try your rake again.

I had a similar issue and I was skeptical about removing a line from my Gemfile.lock, it seemed hacky and the inconvenience of prepend bundle exec to every rake command was not an option either. I fixed this by first going into my Gemfile.lock to see what version of rake was there (in my case it was 11.1.2). My thought was to uninstall rake and install this version. Running gem uninstall rake gave this output:

Select gem to uninstall:

rake-10.5.0

rake-11.1.1

rake-11.1.2

rake-11.2.2

rake-11.3.0

All versions

I uninstalled both rake-11.2.2 and rake-11.3.0. That fixed my problem

I am using the rbenv to manage my Ruby environment.

My global Ruby version is as know as the default Ruby version is 2.7.1, because I set it as rbenv global 2.7.1. However, my rake under Ruby 2.7.1 is 12.3.2

~ $ rake --version

rake, version 12.3.2

My project Ruby version is 2.6.5. however, my rake under Ruby 2.6.5 in my project is 13.0.1

~ $ bundle exec rake --version

rake, version 13.0.1

so I have to uninstall global rake

~ $ gem uninstall rake

and reinstall it back

~ $ gem install rake

Fetching rake-13.0.1.gem
Successfully installed rake-13.0.1

it works! ~~~

I'm not sure whether it will have an influence on other projects. However, so far it works.

I tried another way which is delete Gemfile.lock then run bundle install. After that I run rake db:migrate. And everything works fine.

Although I don't think remove Gemfile.lock is bad practice, but may be; who know.

Go in the Gemfile.lock, find the rake file and update the version there.

I got this error:

Gem::LoadError: You have already activated rake 11.2.2, but your Gemfile requires rake 11.1.2. Prepending bundle exec to your command may solve this.

What I did was to change the version of rake in the Gemfile.lock from: rake (11.1.2) to rake (11.2.2).

Everything worked fine after that.

As mentioned on earlier answers this is a simple issue which happens when your gemset has a rake version that is newer than the version number your Gemfile.lock mentions.

The easiest way to debug this is to run bundle update.

The other ways could be to remove Gemfile.lock and running bundle install or simply deleting the line in Gemfile.lock that corresponds to the rake version and try bundle install. But this might sometimes corrupt the Gemfile. I would prefer the first method because it is the safest and the easiest.

I meet the similar problem. My solution is change the line of rake version "gem 'rake', '~> 10.3'" in file Gemfile, delete Gemfile.lock and run 'bundler install', the new Gemfile.lock will show the new version 10.3.1. Then everything will be fine.

I experienced this issue:

Here's my solution:

Solution 1:

This solution works a lot of the time, simply update the gem causing the issue, say the gem is rack

bundle update rack

Solution 2:

In some cases Solution 1 may not work, and you will need to edit your Gemfile.lock file.

Simply, open your Gemfile.lock file and then change the version to the update requested.

In my case, the gem was rack, I had rack 2.0.7 defined in my Gemfile.lock file, but my application required rack 2.1.2, I simply had to modify it to rack 2.1.2 in the Gemfile.lock file.

I then had to uninstall the previous version of rack which is rack 2.0.7

 gem uninstall rack -v 2.0.7

And finally installed the new gem in production

bundle install --without development test

Solution 3:

In very rare cases Solution 1 and Solution 2 may not work, and you will need to edit your Gemfile before updating the gem.

In my case, the gem was puma, I had puma ~> 3.11 defined in my Gemfile, but my application required puma ~> 4.3.1. At this point running bundle update puma and editing my Gemfile.lock file didn't work, since puma ~> 3.11 version specified in the Gemfile would not allow an update to puma ~> 4.3.1.

I simply had to change the version of puma in the Gemfile to puma ~> 4.3.1 and then ran the command.

bundle update puma

Solution 4:

If the version of rake that your Gemfile requires is less than the rake version activated, and you do not want to update rake, then you can as well run the command below to remove the version of rake that is activated:

gem list rake
gem uninstall rake

and then select the version of rake you want to uninstall.

That's all.

I hope this helps
