启动命令行时出现错误消息且无法更新或安装

我在 Ubuntu 15.04 上收到一条错误消息。我无法安装任何东西,当我打开命令行时会弹出此错误:

bash: /home/lea/.bashrc: line 1: syntax error near unexpected token `('
bash: /home/lea/.bashrc: line 1: `export PATH=/opt/android-sdk-linux/tools:/opt/android-sdk-linux/platform-tools:$PATH# ~/.bashrc: executed by bash(1) for non-login shells.

答案1

  1. 从命令行我输入:

    gedit ~/.bashrc
    
  2. gedit ~/.bashrc開啟。

    它看起来像下面这样:

    PATH=/opt/android-sdk-linux/tools:/opt/android-sdk-linux/platform-tools:$PATH # ~/.bashrc: executed by bash(1) for non-login shells.
    #see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)

          *) return;;
    esac
    
    # don't put duplicate lines or lines starting with space in the history.

        . /etc/bash_completion
      fi
    fi
    
  3. 我编辑了第一行,删除了以下内容:

    PATH=/opt/android-sdk-linux/tools:/opt/android-sdk-linux/platform-tools:$PATH
    
  4. 这是你应该拥有的:

    # ~/.bashrc: executed by bash(1) for non-login shells.

    # for examples

        else

        fi
    fi
    
    if [ "$color_prompt" = yes ]; then
        PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m

    if [ -x /usr/bin/dircolors ]; then
        test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
        alias ls='ls --color=auto'
        #alias dir='dir --color=auto'
        #alias vdir='vdir --color=auto'
        alias grep='grep --color=auto'
        alias fgrep='fgrep --color=auto'

    fi

    if [ -f ~/.bash_aliases ]; then
        . ~/.bash_aliases
    fi
    
    # enable programmable completion features (you don't need to enable

    if ! shopt -oq posix; then

        . /usr/share/bash-completion/bash_completion
      elif [ -f /etc/bash_completion ]; then
        . /etc/bash_completion
      fi
    fi
    
  5. 然后我保存了文件并退出。

  6. 然后我重新启动了我的终端。
