[英]Ruby: Compilation error during installation of ‘rails’ gem on macOS
當我通過運行在 macOS 中安裝 rails 時
$ sudo gem install rails
我得到了以下內容。
Building native extensions. This could take a while...
ERROR: Error installing rails:

************************************************************************
IMPORTANT NOTICE:
Building Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
- 0001-Revert-Missing-initialization-for-the-catalog-module.patch
- 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch
Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:
gem install nokogiri -- --use-system-libraries
[--with-xml2-config=/path/to/xml2-config]
[--with-xslt-config=/path/to/xslt-config]
If you are using Bundler, tell it to use the option:
bundle config build.nokogiri --use-system-libraries
bundle install
Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

使用本機擴展構建 gem 總是很痛苦。 您需要安裝多個庫或編譯工具。 在 nokogiri 的情況下,它是 libxml。 出於這個原因,我建議使用rvm開始。 RVM 不是最干凈的工具,就 Unix 哲學而言,但它是一個全棧解決方案,這意味着它開箱即用。 它將使用默認的 osx 包管理器為您安裝所有依賴項。 作為包管理器,我推薦homebrew 。
#install homebrew
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
#install rvm into $HOME

gem install rails #no sudo, as ruby is in $HOME
