Saya mengatur aplikasi Rails 4 dengan Ruby 2.0, tetapi saya mendapatkan "Aplikasi web tidak dapat dimulai" dan mendapatkan jejak ini:
cannot load such file -- bundler/setup (LoadError)
/usr/local/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:53:in `require'

Apache2.conf saya adalah:
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/buildout/apache2/mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19
PassengerDefaultRuby /usr/local/bin/ruby
bundle -v
adalah:
Bundler version 1.3.5
ruby -v
adalah:
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
gem env
adalah:

echo $GEM_PATH
adalah:
/usr/lib/ruby/gems/1.8:/usr/lib/ruby/gems/1.8
Tidak GEM_PATH
seharusnya /usr/lib/ruby/gems/2.0
?
Di dalam virtual host di apache2.conf saya menambahkan:
SetEnv GEM_HOME /usr/lib/ruby/gems/1.8
Dan sekarang sudah berfungsi.
Apakah ini cara yang tepat untuk memperbaikinya?
sudo
sebenarnya diperlukan? Saya menggunakansudo
tetapi sekarang saya bertanya-tanya apa yang akan terjadi jika saya tidak melakukannya.
