Ruby/RVM with @global gem - bundle 运行因 `require' 失败：无法加载此类文件 — bundler (LoadError)

Question

我学习linux 1个月。当我尝试执行 Migrating from MySQL to Postgres on Heroku 中的所有步骤时，我遇到了无法处理的错误。

当我尝试从源安装 mysqltopostgres gem 时：

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

我在 $ bundle install 上有一个错误：

/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>'

我已经安装了 sudo apt-get install bundler，但是当我尝试输入 bundle -v 时，我得到了同样的错误！

我的gem env是：

请帮助我了解问题所在。我需要安装 mysqltopostgres 以将 MySQL 迁移到 Heroku 中的 Posgres。

谢谢！

1) 只跳过 sudo 运行 gem install bundler

2) 运行 bundle install

现在应该可以了
