rails new blog
したら以下のようなエラーがでた。
An error occurred while installing sqlite3 (1.3.13), and Bundler cannot continue. Make sure that `gem install sqlite3 -v '1.3.13' --source 'https://rubygems.org/'` succeeds before bundling. In Gemfile: sqlite3 [vagrant@localhost blog]$ gem install sqlite3 -v '1.3.13' --source 'https://rubygems.org/' Building native extensions. This could take a while... ERROR: Error installing sqlite3: ERROR: Failed to build gem native extension. current directory: /home/vagrant/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/sqlite3-1.3.13/ext/sqlite3 /home/vagrant/.rbenv/versions/2.5.3/bin/ruby -r ./siteconf20181125-6435-7i5da6.rb extconf.rb checking for sqlite3.h... no sqlite3.h is missing. Try 'brew install sqlite3', 'yum install sqlite-devel' or 'apt-get install libsqlite3-dev' and check your shared library search path (the location where your sqlite3 shared library is located).
書いてあるとおり
gem install sqlite3 -v '1.3.13' --source 'https://rubygems.org/
をしてから
bundle update
してみたけど変わらずエラーが。
よく見たら下の方にsqlite-develいれろって書いてあるので
yum install sqlite-devel
したら解消できた。
