.bashrc：shopt：找不到

刚刚使用Ubuntu 12.04配置了一个新的Rackspace实例,并从他们的 github下载了rbenv并安装了它.

我在执行时遇到以下错误. ./~bashrc

$. ~/.bashrc
sh: 18: /home/deployer/.bashrc: shopt: not found
sh: 26: /home/deployer/.bashrc: shopt: not found
sh: 110: /home/deployer/.bashrc: shopt: not found
sh: 28: /etc/bash_completion: [[: not found
sh: 34: /etc/bash_completion: [[: not found
sh: 51: /etc/bash_completion: Bad substitution

这是我的.bashrc(对于用户部署者),我唯一添加的是顶部的rbenv位.

更新：

测试中要求的测试：

$echo $SHELL
/bin/sh
$ /bin/sh -c 'echo $SHELL'
/bin/sh
$cat /proc/$$/cmdline
sh

您刚发布的输出表明您实际上没有运行bash.这就是为什么你得到错误来源.bashrc.

要解决此问题,您需要检查您的登录shell以确保它实际设置为bash：

chsh -l

将列出可用的shell,和

chsh -s /path/to/bash

将您的登录shell更改为bash.

然后注销并重新登录.
