我尝试安装bundler，它似乎工作，但问题仍然存在

user1@company.com [~]# gem install bundler

user1@company.com [~]# bundle install

这是我的环境

user1@company.com [~]# gem list -d bundler

这很可能是因为您在PATH安装位置之前的位置有一个存根二进制文件/home3/user1/ruby/gems/bin。

如果您将/home3/user1/ruby/gems/bin（或任何gem env打印的EXECUTABLE DIRECTORY）移动到您的前面PATH，它应该可以工作。
