我和我已经安装了rbenv并可以运行ruby -v瑞安的RailsCast集339一起以下。我离开我的会议，当我试图从root回来（通过su deployer，我得到这个错误rbenv：权限拒绝

这里是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() { 
    local cwd="$(pwd)" 
    local path="$1" 

    while [ -n "$path" ]; do 
    cd "${path%/*}" 
    local name="${path##*/}" 
    path="$(resolve_link "$name" || true)" 
    done 

    pwd 
    cd "$cwd" 
} 

if [ -z "${RBENV_ROOT}" ]; then 
    RBENV_ROOT="${HOME}/.rbenv" 
else 
    RBENV_ROOT="${RBENV_ROOT%/}" 
fi 
export RBENV_ROOT

    cd "$RBENV_DIR" 2>/dev/null || { 
    echo "rbenv: cannot change working directory to \`$RBENV_DIR'" 
    exit 1 
    } >&2

    cd "$OLDPWD"

export RBENV_DIR 


shopt -s nullglob

当您将用户切换到“部署者”时，您似乎处于/ root目录中。请确保您位于“部署者”可以访问的目录中。 – d11wtq 2012-03-30 23:41:23

你说得对。我是在'/ root'，我认为部署将有机会获得，因为部署是管理小组。你虽然权，目录的简单的开关让我'su'正确。如果你想把这个作为答案，我会接受它。谢谢。 – 2012-04-03 20:35:52
