Question

Building a new Rails app and getting a problem with nokogiri. Said to try gem install nokogiri -v \'1.6.8.1\' which fails with output below. I tried deleting Gemfil

Answer 1

Run this first:

xcode-select --install

Then rerun your bundle install

Answer 2

I tried @the_basterd's recommendation. That didn't work, but the reference was good—thank you the_basterd. What worked from that reference was:

brew install libxml2

bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2

Reference: https://github.com/sparklemotion/nokogiri/issues/1483

Later postings at that ref said that what I posted above "is strongly recommended against by the Nokogiri."

brew unlink xz; bundle install; brew link xz is preferred.

Answer 3

I ran into this issue with nokogiri-1.6.8.1 while using bundle install --path vendor/bundle to install directly into a project located within a Google Drive sync folder. The hangup seemed related to libxml2.

While reading through the GitHub issue referenced by @Greg and @the_basterd, I noticed that someone was having trouble installing into a Box sync folder. Moving my project folder to another location worked.

Not sure what the underlying problem is when installing to a sync folder, but I'd be interested to learn if anyone had any thoughts.

Haven't tested this with Dropbox, but perhaps that would cause problems, too.

You can also encounter the same error message if you've downloaded XCode Tools but haven't yet agreed to the license.

From Terminal, run:

sudo xcodebuild -license

Enter your admin password, space through the agreement and type agree to accept. Run brew doctor and if necessary, brew update and you should be in good shape.
