Question

我已经在〜/ .bashrc中保存了一些ENV，我关闭并重新打开文件，他们肯定在那里。

.bashrc中：

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

. /etc/apache2/envvars

# If not running interactively, don't do anything else
[ -z "$PS1" ] && return

# don't put duplicate lines or lines starting with space in the history.
# See bash(1) for more options
HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
HISTSIZE=1000
HISTFILESIZE=2000

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
    . /etc/bash_completion
fi

PS1='\[\033[01;32m\]${C9_USER}\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]$(__git_ps1 " (%s)") $ '

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"

export rvm_silence_path_mismatch_check_flag=1

export TWILIO_SID="AXXXXX81b7eb5aXXXXeXXX6c9bfecX6X"
export TWILIO_TOKEN="XXX87XXXXXXe650ff2XXXXfXXXXX8X2"
export TWILIO_PHONE_NUMBER="+147043XXXX"

然而，当我告诉我的rails应用程序使用它们时，例如在我的控制器中使用ENV [“TWILIO_SID”]，它不知道它们。我尝试用bash回显它们，它只是一个空行，用HTML，也是空行。我正在使用c9云IDE，并且有一个选项可以手动将ENV输入到Rails shell中，当我这样做时，一切正常。但我的任务要求bashrc文件...为什么bash和rails终端都没有读取我的.bashrc？有什么帮助吗？

PS：总体目标是在我的Rails应用程序中设置UNIX env变量。我不能用figaro。

PS2：这是我使用变量的控制器中的代码。当我对它们进行硬编码时，一切正常，所以我知道env变量会发生一些事情。

require 'twilio-ruby'

def index
end

class TexterController < ApplicationController
  def index
  end

  def text
    @number = params[:number]
    @message = params[:message]

    twilio_sid =  ENV["TWILIO_SID"]
    twilio_token = ENV["TWILIO_TOKEN"]
    twilio_phone_number = ENV["TWILIO_PHONE_NUMBER"]

    @client = Twilio::REST::Client.new(twilio_sid, twilio_token)

    @message = @client.messages.create(
      to: @number,
      from: twilio_phone_number,
      body: @message
    )

      render "pages/text.html.erb"
  end
end

以下是原因：

永久改变环境变量＆＃34;你至少需要考虑这些情况：

登录/非登录shell
互动/非互动外壳

Bash as login shell将按顺序加载/etc/profile, ~/.bash_profile, ~/.bash_login, ~/.profile

Bash作为非登录交互式shell将加载~/.bashrc

Bash作为非登录非交互式shell将加载环境变量 $ BASH_ENV

中指定的配置

找到它。事实证明，即使我输出.bashrc，也没有读取env变量，但是当我将它们添加到.profile时，它们被读取并且一切正常。甚至尝试将它们添加到.bashrc然后source ~/.bashrc添加到.profile，但仍然无法正常工作。

Rails应用程序不读取.bashrc中的env变量
