为什么在使用sudo时找不到命令“ bundle”：

[root@desktop gitlab]# sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production
sudo: bundle: command not found
[root@desktop gitlab]#

但是在不使用sudo时确实存在：

[root@desktop gitlab]# bundle exec rake gitlab:setup RAILS_ENV=production

This will create the necessary database tables and seed the database.

我问的原因是我正在关注https://github.com/gitlabhq/gitlab-
recipes/tree/master/install/centos，它指出要使用sudo。

所述添加标志…引发’bundle：命令未找到’错误，但显示“此帐户当前不可用”。
