带有@global gem的Ruby / RVM - bundle运行失败，带有`require'：无法加载这样的文件 - bundler（LoadError）

Question

I study linux for 1 month. While I tried to make all steps from Migrating from MySQL to Postgres on Heroku I've got an error I could not handle.

When I try to install the mysqltopostgres gem from source:

$ git clone https://github.com/maxlapshin/mysql2postgres.git
$ cd mysql2postgres
$ bundle install
$ gem build mysqltopostgres.gemspec
$ sudo gem install mysqltopostgres-0.2.20.gem

I have an error on $ bundle install :

/home/franchb/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/core_ext/
kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError) 
from /home/franchb/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/core_ext/
kernel_require.rb:55:in `require'
from /usr/bin/bundle:7:in `<main>'

I've installed sudo apt-get install bundler but when i try enter bundle -v I get the same error!

My gem env is:

Please, help me to understand what goes wrong. I need to install mysqltopostgres to migrate MySQL to Posgres in Heroku.

Thank you!

Answer 1

1) Skip the sudo just run gem install bundler

2) run bundle install

Now it should work
