RubyOnRails/bin/Feder wie folgt aussieht:

#!/usr/bin/env ruby 

# This file loads spring without using Bundler, in order to be fast. 
# It gets overwritten when you run the `spring binstub` command. 

unless defined?(Spring) 
    require 'rubygems' 
    require 'bundler' 

    lockfile = Bundler::LockfileParser.new(Bundler.default_lockfile.read)

Answer 1

ändern Linie 18 Ihrer config/application.rb zu:

Rails.root.join('vendor', 'assets', 'bower_components').to_s.tap do |bower_path| 

root ist nicht definiert, aber Rails.root ist.

Answer 2

In application.rb

# Bower asset paths 
root.join('vendor', 'assets', 'bower_components').to_s.tap do |bower_path| 
    config.sass.load_paths << bower_path 
    config.assets.paths << bower_path 
end 

Sie vermissen Rails vor root:

# Bower asset paths 
Rails.root.join('vendor', 'assets', 'bower_components').to_s.tap do |bower_path| 
    config.sass.load_paths << bower_path 
    config.assets.paths << bower_path 
end 

Answer 3

Wenn Sie

source /home/web/.rvm/scripts/rvm 

jedes Mal, wenn Sie ein Fenster öffnen laufen haben, dann Sie haven Ich habe RVM nicht richtig installiert.

Lesen Sie sorgfältig "Installing RVM" und bestätigen Sie, dass Sie diese Schritte befolgt haben.

Sobald Sie bestätigt haben, dass die Installation korrekt ist, müssen Sie einen Standard-Ruby für RVM festlegen. Zuerst Liste der Rubyies RVM verwaltet:

rvm list 

, die wie etwas zurückgibt:

rvm rubies 

=* ruby-2.4.0 [ x86_64 ] 

# => - current 
# =* - current && default 
# * - default 

dann RVM sagen zu verwenden, ein:

rvm use ruby-2.4.0 --default 

Außerdem ist es eine gute Idee, regelmäßig zu sagen RVM, um sich selbst zu aktualisieren. Führen Sie in der Befehlszeile für weitere Informationen

rvm help get 

aus.
