我跟随Ryan的RailsCast第339集.我已经安装了rbenv并且可以运行ruby -v.我离开我的会议,当我试图回来(通过su deployer从root,我得到这个错误
/home/deployer/.rbenv/bin/rbenv: line 20: cd: /root: Permission denied
这是rbenv文件:
#!/usr/bin/env bash
set -e
[ -n "$RBENV_DEBUG" ] && set -x
resolve_link() {
$(type -p greadlink readlink | head -1) "$1"
}
abs_dirname() {

我passenger-install-nginx-module开始运行然后我得到了
Please specify a prefix directory [/opt/nginx]:
--------------------------------------------
Permission problems
This installer must be able to write to the following directory:
/opt/nginx
But it can't do that, because you're running the installer as deployer.
好的,我跑了sudo passenger-install-nginx-module然后跑了sudo: passenger-install-nginx-module: command not found.
这是否意味着我必须以root用户身份安装它,为root用户安装整个rbenv然后安装乘客？我读过的每个教程都是从非root用户帐户运行的:/,它对我不起作用.
我在bash提示符中使用以下行安装了pry和相关的gem:
gem install pry-plus --no-ri --no-rdoc
该命令报告了成功的gem安装.
我发现的所有说明都说安装pry之后我可以通过输入prybash命令来获得pry提示符.但是,实际结果是bash: pry: command not found
which pry报告no pry in (...)省略号为$ PATH的位置.相比之下,which rake报告/local/tbh/rbenv/shims/rake和which gem报告/local/tbh/rbenv/shims/gem
为什么pry的命令不是由gem install创建的？我怎样才能让它按设计工作？
(我在Scientific Linux下使用Ruby 1.9.3和rbenv(不是RVM)作为虚拟环境.)
我使用的是OSX 10.8.4
我尝试使用以下方法设置我的全局ruby版本:
$ rbenv global 1.9.3-p429
$ rbenv version
>> 1.9.3-p194 (set by /Users/emailnitram/.ruby-version)
我的PATH看起来像这样:
/Users/emailnitram/.rbenv/shims:/Users/emailnitram/.rbenv/bin:/usr/local/opt/ruby/bin:/usr/local/heroku/bin:/Users/emailnitram/Sites/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/Users/emailnitram/.rbenv/shims:/Users/emailnitram/.rbenv/bin:/usr/local/opt/ruby/bin:/usr/local/heroku/bin:/Users/emailnitram/Sites/bin
我试过看rbenv不改变ruby版本并按照说明确保我的〜/ .bash_profile中有以下内容
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
我仍然需要设置rbenv local 1.9.3-p429让它工作
我在使用rbenv管理的VM(VirtualBox)中安装了MailCatcher.但是,mailcatcher不起作用,在下面输出错误信息:
`require': cannot load such file -- i18n/core_ext/string/interpolate (LoadError)
似乎i18n没有安装,但我安装了它.
[vagrant@localhost ~]$ gem list i18n
*** LOCAL GEMS ***
i18n (0.7.0.beta1)
我在AWS EC2中安装与此相同,它可以工作.
我的VM发生了什么？

所以,我rbenv通过Homebrew,然后Ruby 2.2(rbenv install 2.2)安装,最后gem install sass,但我无法sass在我的$PATH.
时间紧迫,我sudo gem install sass使用我的系统(Yosemite)默认的Ruby 2.这把所有/Library/Ruby/Gems/2.0.0东西都放进去,事情确实有效,但不是最需要的.
理想情况下,使用rbenv我应该能够安装任何Ruby版本,并在该版本的目录中安装宝石,然后进行符号链接/usrl/local/bin.
任何可能出错的帮助都将非常感激.
我在OS X 10.10.3上安装:自制软件,命令行工具,然后使用rbenv安装ruby:
