ruby on rails - Failed to build gem native extension nio4r in Vagrant SSH windows 7 32-bit -


i'm setting rails environment using vagrant box ubuntu/trusty32 in windows 7 32-bit host. i'm stuck bundle install --path=./vendor/bundle. got following error:

gem::ext::builderror: error: failed build gem native extension.      current directory: /vagrant/vendor/bundle/ruby/2.4.0/gems/nio4r-2.1.0/ext/nio4r /home/vagrant/.rbenv/versions/2.4.1/bin/ruby -r ./siteconf20170911-24730-8nkvsn.rb extconf.rb checking unistd.h... yes checking sys/select.h... yes checking poll.h... yes checking sys/epoll.h... yes checking sys/event.h... no checking port.h... no checking sys/resource.h... yes creating makefile  text file busy @ unlink_internal - ./siteconf20170911-24730-8nkvsn.rb  gem files remain installed in /vagrant/vendor/bundle/ruby/2.4.0/gems/nio4r-2.1.0 inspection. results logged /vagrant/vendor/bundle/ruby/2.4.0/extensions/x86-linux/2.4.0-static/nio4r-2.1.0/gem_make.out  error occurred while installing nio4r (2.1.0), , bundler cannot continue. make sure `gem install nio4r -v '2.1.0'` succeeds before bundling.  in gemfile:   rails_admin resolved 1.2.0, depends on     rails resolved 5.0.6, depends on       actioncable resolved 5.0.6, depends on         nio4r

the problem seems issue of gem nio4r. have tried these:

  • gem install bundler
  • bundle update
  • gem uninstall nio4r
  • gem install nio4r (this installed gem)
  • rm gemfile.lock
  • bundle install

none of above works. tried this:

sudo apt-get install ruby2.2-dev

but couldn't find package.

e: unable locate package ruby2.2-dev e: couldn't find package regex 'ruby2.2-dev'

the error addresses message text file busy @ unlink_internal - ./siteconf20170911-24730-8nkvsn.rb. i found solution , followed steps described in article.

by changing bundle path directory that's local vm (not on shared folder) made error gone away.

  1. create new directory

    mkdir ~/.bundles

  2. add /vagrant/.bundle/config

    bundle_path: "/home/vagrant/.bundles/project_name_here" bundle_disable_shared_gems: "1"
  3. run bundle install
