Installing RVM to /Users/manishgiri/.rvm/
    Adding rvm PATH line to /Users/manishgiri/.profile /Users/manishgiri/.mkshrc /Users/manishgiri/.bashrc /Users/manishgiri/.zshrc.
    Adding rvm loading line to /Users/manishgiri/.profile /Users/manishgiri/.bash_profile /Users/manishgiri/.zlogin.
Installation of RVM in /Users/manishgiri/.rvm/ is almost complete:

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

Manish-MBP:~ manishgiri$brew update
Error: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew,other
software may change permissions on this directory. Some versions of the
"InstantOn" component of Airfoil are known to do this.

You should probably change the ownership and permissions of /usr/local
back to your user account.

看起来自制软件有问题,所以我决定更新它.我做了更改所有权和权限部分,并按照此问题的说明 – How do I update Homebrew?并执行brew更新.我得到了一份最新的回复.

接下来,我尝试了第一个答案中已知的rvm list,只是为了验证最新版本,然后我执行了rvm install current&& rvm使用电流.我收到了这个回复：

Now using system ruby.

毕竟,我认为它会升级到2.2.3但是当我运行ruby -v时,我仍然得到：ruby 2.0.0p645(2015-04-13修订版50299)[universal.x86_64-darwin15].

为什么更新失败了？我在我的Windows PC上安装了RubyInstaller,它使用的是2.2.3.
