<\/p>\n<\/p>\n
Today I talk about how I fixed “Failed to build nokogiri\u00a01.8.3” on Fedora 28.<\/p>\n
<\/p>\n
At the moment any ruby applications that requires nokogiri\u00a01.8.3 in the Gemfile will fail to build. This is due to an issue with the libraries packaged in Fedora.<\/p>\n
As far as I can tell from the bug reports, this is only present in Fedora due to how ruby and the dev files are packaged.<\/p>\n
Commonly this is shown up with a similar error to:<\/p>\n
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.\r\n\r\ncurrent directory: \/usr\/share\/gems\/gems\/nokogiri-1.8.3\/ext\/nokogiri\r\n\/usr\/bin\/ruby -r .\/siteconf20180624-5605-fp1465.rb extconf.rb\r\nmkmf.rb can't find header files for ruby at \/usr\/share\/include\/ruby.h\r\n\r\nextconf failed, exit code 1\r\n\r\nGem files will remain installed in \/usr\/share\/gems\/gems\/nokogiri-1.8.3 for\r\ninspection.\r\nResults logged to \/usr\/lib64\/gems\/ruby\/nokogiri-1.8.3\/gem_make.out\r\n\r\nAn error occurred while installing nokogiri (1.8.3), and Bundler cannot\r\ncontinue.\r\nMake sure that `gem install nokogiri -v '1.8.3' --source\r\n'https:\/\/rubygems.org\/'` succeeds before bundling.\r\n\r\nIn Gemfile:\r\nrails was resolved to 4.2.8, which depends on\r\nactionmailer was resolved to 4.2.8, which depends on\r\nactionpack was resolved to 4.2.8, which depends on\r\nactionview was resolved to 4.2.8, which depends on\r\nrails-dom-testing was resolved to 1.0.9, which depends on\r\nnokogiri<\/pre>\nFixing this by changing the Gemfile requirements<\/h2>\n
I got this error because I was installing Redmine which required the\u00a0nokogiri version to be:<\/p>\n
gem \"nokogiri\", (RUBY_VERSION >= \"2.1\" ? \"~> 1.8.1\" : \"~> 1.6.8\"<\/pre>\nThis selected the 1.8.3 version of nokogiri which as above it is impossible to install currently.<\/p>\n
To resolve this I installed the nokogiri\u00a0in Fedora using the following command:<\/p>\n
sudo dnf install rubygem-nokogiri<\/pre>\nAfter installing I noted down which version it had installed by reading the install log (example below).<\/p>\n
Installed:\r\nrubygem-nokogiri.x86_64 1.8.2<\/strong>-1.fc28<\/pre>\nOnce I had worked out that I have installed 1.8.2 I then went back into the gemfile. By modifying it to specify nokogiri should use 1.8.2 (the version I just installed) the install then worked fine. I changed the gemfile to say:<\/p>\n
gem \"nokogiri\", \"1.8.2\"<\/pre>\nAfter changing this I was able to install redmine\u00a0as expected using
bundler install<\/code>.<\/p>\nIt is hoped that the issue with this package will be resolved quickly and the Fedora project will update the version in dnf however until then this fix will resolve the issue.<\/p>\n","protected":false},"excerpt":{"rendered":"
