I wanna deploy my grails application on AppFog. To do this, I've installed Ruby 22 x64 and devkit mengv64. I've extracted devkit.7z to C:\ruby, done commands: dk.rb install,dk.rb init. Then, I entered a command: gem install af,
but I got such error: Error installing af: failed to build gem native extension. How to fix it?
There is often an issue with the escape_utils gem. This a general limitation of RubyGems. If there's a problem with a gem dependencies, new installs of the af gem or updates to any of its gem dependencies can screw things up. That's why AppFog v2 is testing a binary executable to avoid this mess.
That being said, the general practice for installing on Windows is to install the Ruby environment you want and install the appropriate dev kit. When that's done, you'll need to find the Ruby Enabled Command Prompt. Usually, Start > Programs > Ruby*. Everything below should now be done from there:
ruby dk.rb install
ruby dk.rb init
gem update --system
gem install escape_utils -v 1.0.1
This gem regularly has problems, especially for Windows, so this is usually the best version to go with for the time being.
gem install af
Here's AF's article for installing the gem on Windows: Installing the AF CLI Tool on Windows.
Either the App Fog gem requires a native extension, or one of its dependencies does.
Does the error show which gem is failing?
According to RubyGems, there are some dependencies. I don't see which one would require a native extension.
So, you may want to try installing the dependencies and see if one of them fails.

I'm trying to get Compass installed on a 2020 Mac Book Pro running Big Sur (11.5.2).
When I try and run:
gem install compass
I get the error:
You don't have write permissions for the /Library/Ruby/Gems/2.6.0 directory
If I try and run:
sudo gem install compass
I get the error:

Anyone have any ideas on how to get Compass installed?
This really decomposes to two issues, as you noticed with the sudo call.
(1) You're trying to write gems to the protected directory for your system Ruby.
In most development environments, it's best to install a Ruby version manager that allows you to install multiple Rubies side-by-side for different projects. Purely subjectively, I'd recommend rbenv to manage only Ruby, or asdf to manage Ruby versions along with other languages versions. However, the question of which Ruby version manager to use is very well tread already, so you can pick the solution that's best for your needs with existing information.
(2) You're installing a gem with native extensions, which means that you need the underlying C libraries installed on your system to build correctly (assuming you're using CRuby, the default Ruby implementation). You'll need to install libffi-dev on your machine to build that gem correctly. Based on this question, it seems a simple brew install libffi should work for that.
Lastly, I'll suggest that it's idiomatic to use the bundler gem to manage gems per-project with Ruby. I'd reconsider if you really want to run this gem system-wide, or if it might vary versions across multiple projects.
I've written a Ruby gem that I'd like to install locally. I'm using Rubygems 3.0.6 and RVM on OS X Mojave. This is a closed source gem and I'd rather not go to the trouble of publishing it to the company gemservers. I'm able to install other (published) gems just fine using both bundle install and gem install.
The gem is all built (using gem build) and the code works, but when I run:
gem install influx_trello_utility-0.1.0.gem
I get an error:
ERROR: While executing gem ... (Gem::Package::PathError)
installing into parent path /bin/[ of /Users/danascheider/.rvm/gems/ruby-2.6.3#influx_trello_utility/gems/influx_trello_utility-0.1.0 is not allowed
Any help with this would be much appreciated. I'm not sure what additional information would be useful, but I'm happy to answer any questions you may have. Thanks!
I am trying to setup my rails application on Windows 7 machine. I installed Ruby 1.9.3 by using installer. I also installed Rails 3.2.2.
Now, I am trying to run bundle install from my application root directory. This command used to install all the required gems. However, when I am running in this new machine its not installing. I have to install all the gems manually one by one.
I know its bit strange but I am facing this for the first time..!!
Edit 1: Please refer below screen-shot.
Note: I have already installed few gems manually before posting here. The error related to DevKit that I am getting below has just came while I was tried to install json gem..
After Installing more gems manually:
If you read the error, it tells you that you need DevKit to install that gem on Windows. So install that and follow the instructions, then try again ;) After the json gem can be installed, it should install every other gem in the Gemfile.
(The json gem is a dependency from Rails)
I am trying to install sproutcore on a windows xp vm (virtualbox), for development, using RubyGems. When gems reaches haml-3.0.25.gem it stops with the error:
gem install sproutcore -V
...
ERROR: While executing gem ... (Zlib::DataError)
invalid stored block lengths
I have tried both Ruby 1.8.7 and 1.9.2 as well as RubyGems 1.7.1 and 1.8.1.
I tried downloading haml 3.1.1 with git and installing it manually, but the rake would not install. It said something about 'lib/haml' not found. The directory did exist.
Other gems install just fine under all the combinations I tried. I even tried installing it under my host OS (Win 7 32-bit), but it gave the same error. Installing haml by itself changes the error message only slightly:
gem install haml -V
...
ERROR: While executing gem ... (Zlib::DataError)
invalid code lengths set
Zlib compresses and decompresses data streams from what I have read, so it sounds like the haml gem might be corrupt (although I doubt).
I am at my wits end and could find no helpful advice anywhere.
Special thanks to #saner for his contribution. After a lot of frustration, this is how I finally installed sproutcore on a Windows XP VM running on a Windows 7 host.
1) Download and install Ruby 1.9.2-p180 (remember to tick the option to include the bin directory in the PATH variable).
2) Download DevKit 4.5.1 and extract it.
3) Open a command prompt and cd to the extracted directory.
4) Run:
ruby dk.rb init
ruby dk.rb review
ruby dk.rb install
5) Download RubyGems 1.7.2 and run setup.rb
6) From the command prompt run
gem install haml -v 3.0.24
gem install eventmachine --pre
gem install sproutcore --pre
Thats it.
Enjoy.
I was able to install SproutCore on Ruby 1.9.2:
Install Ruby 1.9.2-p180
gem install sproutcore --pre
gem install eventmachine --pre
gem uninstall thin
gem install mongrel
I needed to remove thin because starting sc-server ended with errors, SproutCore will use mongrel instead of thin.
Update:
I didn't mention that I use RubyGems 1.7.2 and I have installed DevKit and Cygwin.
I removed all versions of SproutCore, Mongrel and Haml, then I typed:
gem install sproutcore --pre, SproutCore v1.6.0.beta.1 was installed.
eventmachine --pre, eventmachine (1.0.0.beta.3 x86-mingw32) was installed
SproutCore works with this setup, using mongrel was not necessary.
My configuration: sproutcore (1.6.0.beta.1), ruby 1.9.2p180, gem 1.7.2, thin (1.2.11 x86-mingw32), eventmachine (1.0.0.beta.3 x86-mingw32), haml (3.0.25), gcc version 4.5.0 (GCC)
I know this is a really old question, but since I just experienced the same problem, I've decided to add my insights on it.
So, it happened while I was trying to install the same set of gems on two different machines with different architectures, with different locations and respectively in different networks. I.e. - my home mac and a remote linux server.
So, one particular gem (dm-sqlite-adapter) failed installing on both machines, and I even tried it couple of times, but always with the same result:
$ gem install dm-sqlite-adapter
ERROR: While executing gem ... (Zlib::DataError)
invalid code lengths set
Then I spent few minutes browsing the network for a solution, including reading this thread.
Since I didn't find any satisfying answer and I wasn't pleased with the idea of reinstalling everything, decided to act dumb and tried gem install one more time.. And it worked. Then tried the other machine - worked like a charm.
So as a conclusion I'd just guess that the problem came from the remote repo and maybe the gem hadn't even downloaded at all (I forgot to check that prior to succeeding installing it). But as I said - it's just a guess..
We have a ruby application that depends on a gem with native extensions (in this specific case Nokogiri). However, for various reasons we cannot install the build prerequisites (such as build-essential, libxslt-dev, ruby-dev, etc) for that gem onto our production host.
Is there a (standard?) way to repackage the gem with the native extensions pre-built?
It should be possible (it seems to be fairly standard to do this for Windows), but I can't find any documentation on the subject.
Note that we only need to support a single platform, with known versions of all system libraries (Ubuntu 9.04 Server 64 bit, Ruby 1.8.7).
UPDATE:
We're using Bundler, so we want to still have a gem to install at the end of the day, not a debian package.
Finally found a way to do this for gems that use rake-compiler for building their C extensions (which is most of them).
You need to do the following on a machine that is identical to the one you want to deploy to, or it simply won't work:
Install the build prerequisites for building C extensions:
# apt-get install build-essentials ruby-dev # ... etc
# gem install rake-compiler
Unpack the gem you want to rebuild:
$ gem unpack nokogiri
Build your shiny new precompiled gem:
$ rake native gem
You can now install the native gem on a machine without any build tools installed:
$ gem install pkg/nokogiri-1.4.3.1-x86-linux.gem
Successfully installed nokogiri-1.4.3.1-x86-linux
1 gem installed
Build machine
To have the correctly platformed version for all of your gems already cached,
package all gems in vendor/cache on an identical machine:
$ bundle package --all
Prduction machine
Install all gem dependecies already cached that requires to have the correctly
platformed version using the gem cache:
$ bundle install --local --deployment
