.bashrc：shopt：未找到

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 并安装它。

执行时出现以下错误. ./~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（用于用户部署者），我唯一添加的是在顶部的 rbenv 位。

评论中要求进行的测试：

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

答案1

您刚刚发布的输出表明您实际上并未运行bash。这就是您收到错误来源的原因.bashrc。

要修复此问题，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，并且

chsh -s /path/to/bash

将会把您的登录 shell 更改为 bash。

然后注销并重新登录。

答案2

shopt是 bash 内置程序，而不是独立可执行程序，因此source无法运行。这就是您收到该错误的原因。您想要完成什么？

答案3

当您bashrc从其他 shell（如 zsh）获取文件时，会出现此问题。请确保当前 shell 的 rc 文件中不存在此行

source ~/.bashrc

要检查当前 shell，请执行：

echo $SHELL
