ruby on rails - How do I get Bundler gem to work without doing /bin/bash --login -

-

i've been following lot of instructions on how fix rails installation without understanding everything. can create new rails app now, if type

/bin/bash --login

in terminal first. if don't first, the

rails new

command fails when gets part with

bundle install

this first line of error message when fails:

/usr/lib/ruby/2.2.0/rubygems.rb:243:in `bin_path': can't find gem bundler (>= 0) (gem::gemnotfoundexception)

is there path setting or can fix can make new rails app in virgin terminal window? also, bin/bash --login do? doesn't change command prompt, , thought logged in when entered password start linux.

i recommend use:

rails <version> new <appname>

... <version> rails version wish use (e.g. _4.2.0_) , <appname> name of app wish create. make sure @ root of workspace when run command.

/bin/bash --login invoke bash non-interactive shell , execute commands /etc/profile. after reading file, looks ~/.bash_profile, ~/.bash_login, , ~/.profile, in order, , reads , executes commands first 1 exists , readable. --noprofile option may used when shell started inhibit behavior. see detailed documentation here. so, when run this, possible setting environment variables when allow rails app created.
