Question

我正在运行ubuntu 16.04桌面，并尝试让RVM正常工作以便我可以：

安装并使用最新稳定版本的ruby。
在没有SUDO权限的情况下，在必要时安装Ruby gem。

为此，这就是我所做的：

按照官方RVM网站上的说明安装RVM：https://rvm.io/

# This keyserver can't be found, btw. So this bit doesn't work.
$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

gpg: requesting key D39DC0E3 from hkp server keys.gnupg.net
?: keys.gnupg.net: Host not found
gpgkeys: HTTP fetch error 7: couldn't connect: Success
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
gpg: keyserver communications error: keyserver unreachable
gpg: keyserver communications error: public key not found
gpg: keyserver receive failed: public key not found

# Install RVM w/ ruby.
$ \curl -sSL https://get.rvm.io | bash -s stable --ruby

rvm 1.27.0 (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]
Already installed ruby-2.3.0.
To reinstall use:

    rvm reinstall ruby-2.3.0

Creating alias default for ruby-2.3.0....

  * To start using RVM you need to run `source /home/rdegges/.rvm/scripts/rvm`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

此时，即使无法导入GPG密钥，我也能够成功安装RVM / Ruby。

我通过在~/.zshrc文件中包含以下代码段来获取RVM文件：

PATH=$PATH:$HOME/.rvm/bin
[[ -s "~/.rvm/scripts/rvm" ]] && source "~/.rvm/scripts/rvm"

这很有效，我可以通过回复我的$ PATH来证实这一点，例如：

$ echo $PATH
...:/home/rdegges/.rvm/bin

最后，如果我使用rvm输出已安装的ruby版本列表，我看到安装了ruby：

$ rvm list
rvm rubies

=* ruby-2.3.0 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

这使我看起来好像我安装了ruby 2.3.0并默认。

在这里，事情变得奇怪......

如果我说which ruby，我会：

$ which ruby
/usr/bin/ruby

我希望看到我的ruby版本来自~/.rvm。

其次，当我尝试安装任何gem时，例如：travis，我收到以下权限错误：

$ gem install travis
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.3.0 directory.

显然，这不是事情本应该起作用的方式。 RVM应该为我的用户本地安装ruby，以便我可以安装gem并使用不同版本的ruby而无需覆盖系统文件和包。

我一定做错了什么，但我花了几个小时搜索stackoverflow，官方rvm文档等等，并且找不到解决方案。

我做错了什么？

如何让RVM在Ubuntu 16.04上为本地用户工作？
