如何修复损坏的 Ruby 配置

Question

I use a MacOs High Sierra 10.13.6. bundle install does not work anymore. I had been using the bundler to run fastlane lanes for years on this machine. I recently installed other sofware and I guess I made a mistake and broke the configuration.

I have the following Gemfile:

source " https://rubygems.org "

gem 'fastlane', '2.120.0'
gem 'aws-sdk', '2.10.8'
gem 'awscli', '0.2.8'
gem 'rake', '12.0.0'
gem 'danger', '5.4.3'

plugins_path = File.join(File.dirname(__FILE__), 'fastlane', 'Pluginfile')
eval(File.read(plugins_path), binding) if File.exist?(plugins_path)

When I try to run bundle install I get the error:

ERROR: cannot discover where libxml2 is located on your system. please make sure pkg-config is installed.

An error occurred while installing nokogiri (1.8.2), and Bundler cannot continue. Make sure that gem install nokogiri -v '1.8.2' --source ' https://rubygems.org/ ' succeeds before bundling.

if I run:

gem install nokogiri -v '1.8.2'

or

gem install nokogiri -v 1.8.2 -n /usr/local/bin -- --use-system-libraries

I get the error:

ERROR: While executing gem ... (Errno::EACCES) Permission denied @ rb_sysopen - /Library/Ruby/Gems/2.3.0/gems/nokogiri-1.8.2/.autotest

I have tried to change the permission of the folder and run:

gem install pkg-config -n /usr/local/bin -- --use-system-libraries
gem install nakogiri -v 1.8.2 -n /usr/local/bin -- --use-system-libraries

As suggested by one of the error messages I have also run:

bundle config build.nokogiri --use-system-libraries

In this case these commands succeed but the bundle install still fails with the same error.

Answer 1

I installed rvm . Then in the .zshrc file I appended:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

Then I run:

rvm reinstall all --force

and now it is working.
