我的WSL终端失去了颜色

Question

出于某种原因，当我在Windows中启动Ubuntu终端时，在我键入bash之前它不会显示颜色。可能是什么原因，我该如何解决？当我安装WSL时，它总是显示颜色。

Answer 1

原因可能是修改后的bash_profile文件。尝试将这些行放到〜/ .bash_profile中

source ~/.bashrc

或者从终端运行命令

echo "source ~/.bashrc" >> ~/.bash_profile

我跑进这个论坛，希望能找到解决问题的方法。我最终弄清楚了，所以这就是我修复它的方法：

1. 按Ctl + r打开终端窗口，输入bash并按Enter键。
2. 通过执行cd ~确保您在主目录中
3. 通过执行nano .bashrc打开bashrc文件
4. 删除该文件中的所有内容并将其替换为：

   # ~/.bashrc: executed by bash(1) for non-login shells.
   # see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
   # for examples
   
   # If not running interactively, don't do anything
   case $- in
       *i*) ;;
       *) return;;
   esac
   
   # don't put duplicate lines or lines starting with space in the history.
   # See bash(1) for more options
   HISTCONTROL=ignoreboth
   
   # append to the history file, don't overwrite it
   shopt -s histappend
   
   # for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
   HISTSIZE=1000
   HISTFILESIZE=2000
   
   # check the window size after each command and, if necessary,
   # update the values of LINES and COLUMNS.
   shopt -s checkwinsize
   
   # If set, the pattern "**" used in a pathname expansion context will
   # match all files and zero or more directories and subdirectories.
   #shopt -s globstar
   
   # make less more friendly for non-text input files, see lesspipe(1)
   [ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"
   
   # set variable identifying the chroot you work in (used in the prompt below)
   if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then
       debian_chroot=$(cat /etc/debian_chroot)
   fi
   
   # set a fancy prompt (non-color, unless we know we "want" color)
   case "$TERM" in
       xterm-color|*-256color) color_prompt=yes;;
   esac
   
   # uncomment for a colored prompt, if the terminal has the capability; turned
   # off by default to not distract the user: the focus in a terminal window
   # should be on the output of commands, not on the prompt
   #force_color_prompt=yes
   
   if [ -n "$force_color_prompt" ]; then
       if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
       # We have color support; assume it's compliant with Ecma-48
       # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
       # a case would tend to support setf rather than setaf.)
       color_prompt=yes
       else
       color_prompt=
       fi
   fi
   
   if [ "$color_prompt" = yes ]; then
       PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
   else
       PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
   fi
   unset color_prompt force_color_prompt
   
   # If this is an xterm set the title to user@host:dir
   case "$TERM" in
   xterm*|rxvt*)
       PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
       ;;
   *)
       ;;
   esac
   
   # enable color support of ls and also add handy aliases
   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'
       alias egrep='egrep --color=auto'
   fi
   
   # colored GCC warnings and errors
   #export GCC_COLORS='error=01;31:warning=01;35:note=01;36:caret=01;32:locus=01:quote=01'
   
   # some more ls aliases
   alias ll='ls -alF'
   alias la='ls -A'
   alias l='ls -CF'
   
   # Add an "alert" alias for long running commands.  Use like so:
   #   sleep 10; alert
   alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"'
   
   # Alias definitions.
   # You may want to put all your additions into a separate file like
   # ~/.bash_aliases, instead of adding them here directly.
   # See /usr/share/doc/bash-doc/examples in the bash-doc package.
   
   if [ -f ~/.bash_aliases ]; then
       . ~/.bash_aliases
   fi
   
   # enable programmable completion features (you don't need to enable
   # this, if it's already enabled in /etc/bash.bashrc and /etc/profile
   # sources /etc/bash.bashrc).
   if ! shopt -oq posix; then
   if [ -f /usr/share/bash-completion/bash_completion ]; then
       . /usr/share/bash-completion/bash_completion
   elif [ -f /etc/bash_completion ]; then
       . /etc/bash_completion
   fi
   fi

5. 使用Ctl + o保存文件
6. 重新加载终端。如果它不起作用，请尝试执行. .bashrc。 （注意最后一个命令中两个句点之间的空格）。

我不知道原始海报是否会得到这个，但希望它能帮助一个偶然发现它的可怜的灵魂。

我最近遇到了同样的问题;我的想法是MS更新了快捷方式，它以某种方式默认为没有颜色？我想我可能会记录是否有人偶然发现了这篇文章。

如果你打开你的开始菜单，向下滚动到“Ubuntu”，现在应该有两个项目：Ubuntu（带有完整的橙色图标）和Ubuntu终端（只有圆形规范徽标）。打开Ubuntu提供标准的彩色终端，而打开Ubuntu终端则提供纯灰色终端。

要修复，要么更改快捷方式（之后应该没问题），要么尝试wsltty：

• wsltty - 看起来真的很花哨，似乎支持更好的复制/粘贴在默认的终端窗口 - 可能是一个更好的选择
