是否可以在 shell 脚本中加载 rvm。谁能举个例子。当我尝试使用 shell 脚本时。我正在使用 ubuntu 系统
#!/bin/bash
rvm use 1.9.3
it gives me error
它给了我错误
RVM is not a function, selecting rubies with 'rvm use ...' will not work.
You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

You can just include rvm in your script by doing:
您可以通过执行以下操作在脚本中包含 rvm：
source ~/.rvm/scripts/rvm
then rvm should be available to your script,
那么 rvm 应该可用于您的脚本，

for simply executing a command against a RVM managed Ruby (or system Ruby) do :
为了简单地针对 RVM 管理的 Ruby（或系统 Ruby）执行命令，请执行以下操作：
rvm 1.9.3 exec camper_van
this assumes rvm use 1.9.3and gem install camper_vanhappened previously which provides the camper_vanexecutable
这假设rvm use 1.9.3并且gem install camper_van之前发生过，它提供了camper_van可执行文件
NOTE: RVM is expected to be loaded already - which it usually is for scripts started under your user (the RVM is not a function, selecting rubies with 'rvm use ...'confirms it's there already).
注意：RVM 预计已经加载 - 通常用于在您的用户下启动的脚本（RVM is not a function, selecting rubies with 'rvm use ...'确认它已经存在）。

# Load RVM into a shell session *as a function*
# Loading RVM *as a function* is mandatory
# so that we can use 'rvm use <specific version>'
if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then
# First try to load from a user install
source "$HOME/.rvm/scripts/rvm"
echo "using user install $HOME/.rvm/scripts/rvm"
elif [[ -s "/usr/local/rvm/scripts/rvm" ]] ; then
# Then try to load from a root install
source "/usr/local/rvm/scripts/rvm"
echo "using root install /usr/local/rvm/scripts/rvm"
else
echo "ERROR: An RVM installation was not found.\n"
fi
