我正在使用Vagrant VirtualBox为我的Rails应用程序设置一个虚拟机.我正在清理Vagrantfile中引用的.sh配置脚本,如下所示：

config.vm.provision "shell",path: "script/provision-script.sh"

提供脚本做了很多事情,但是最终应该安装rbenv Ruby版本控制,然后使用rbenv来安装Ruby 2.2.1.条款脚本的这一部分如下所示：

echo "setting up rbenv"
# execute the remaining commands as vagrant user,instead of root
sudo -H -u vagrant bash -c "git clone https://github.com/sstephenson/rbenv.git ~vagrant/.rbenv"
sudo -H -u vagrant bash -c "git clone https://github.com/sstephenson/ruby-build.git ~vagrant/.rbenv/plugins/ruby-build"
sudo -H -u vagrant bash -c "git clone https://github.com/sstephenson/rbenv-gem-rehash.git ~vagrant/.rbenv/plugins/rbenv-gem-rehash"
echo "setting up rbenv environment in bash"
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~vagrant/.bashrc
echo 'eval "$(rbenv init -)"' >> ~vagrant/.bashrc

# start new vagrant shell so rbenv will work
echo "building ruby"
su vagrant
rbenv install 2.2.1 && rbenv global 2.2.1 && rbenv rehash && cd /path/to/my/app && gem install bundler rake && rbenv rehash && bundle && rbenv rehash

一切到rbenv安装…部分正常工作.安装ruby失败,并显示以下错误：

==> default: setting up rbenv
==> default: Cloning into '/home/vagrant/.rbenv'...
==> default: Cloning into '/home/vagrant/.rbenv/plugins/ruby-build'...
==> default: Cloning into '/home/vagrant/.rbenv/plugins/rbenv-gem-rehash'...
==> default: setting up rbenv environment in bash
==> default: building ruby
==> default: /tmp/vagrant-shell: line 73: rbenv: command not found

然后脚本完成.我可以用vagrant ssh打开vm,然后成功运行rbenv install 2.2.1,所以我猜测在配置过程中,一个新的vagrant shell并没有被启动.我的印象是,这应该是在rbenv安装之前发生的su vagrant 2.2.1.

我可以做些什么来确保在此配置期间初始化新的shell,并且rbenv命令将工作？

解决方法

我有类似的问题,因为我正在尝试安装rbenv,流氓配置给我的错误：

==> default: /tmp/vagrant-shell: line 10: rbenv: command not found

首先,了解vagrant配置脚本是以sudo模式运行非常重要的.
所以,当进入脚本时,我们引用?/ path,我们引用/ root / path,而不是/ home / vagrant / path.
问题是我正在为root用户安装rbenv,并尝试从vagrant用户调用rbenv命令,当然它没有工作！

所以我做的是指定在无sudo用户添加特权的情况下运行配置者：false：

config.vm.provision :shell,privileged: false,inline: $script

然后进入我的脚本,我正在考虑一切都是从流氓用户呼叫的.
这里@Casper的答案帮了我很多,因为它只能指定：
sudo -H -u vagrant bash -i -c’……’

Since you just updated .bashrc with a new path and other settings,you
will want to run “sudo bash” with the -i option. This will force bash
to simulate an interactive login shell,and therefore read .bashrc and
load the correct path for rbenv.

在我最后的Vagrantfile下面.

# -*- mode: ruby -*-
# vi: set ft=ruby :

$script = <<SCRIPT

  git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
  echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
  echo 'eval "$(rbenv init -)"'               >> ~/.bashrc
  source ~/.bashrc

  git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

  # config.vm.provider :virtualbox do |vb|
  #   vb.customize ["modifyvm",:id,"--memory","1024"]
  # end

  config.vm.provision :shell,inline: $script
end

希望对别人有帮助.
