如何修复cygwin的自动颜色？

# ~/.bashrc

# 设置PS1变量以支持颜色
PS1='\[\e[0;32m\]\u@\h \[\e[0;33m\]\w\[\e[0m\] \$ '

# ~/.bashrc

# 启用ls颜色
alias ls='ls --color=auto'

# 安装coreutils包
apt-cyg install coreutils

# ~/.bashrc

# 配置dircolors
eval "$(dircolors -b ~/.dircolors)"

# ~/.dircolors

# Configuration file for dircolors, a utility to help you set the
# LS_COLORS environment variable used by GNU ls with the --color option.

# Below are the color init strings for the basic file types. A color init
# string consists of one or more of the following numeric codes:
# Attribute codes:
# 00 = default color
# 01 = bold
# 04 = underscore
# 05 = blink
# 07 = reverse
# 08 = concealed
# Text color codes:
# 30 = black
# 31 = red
# 32 = green
# 33 = yellow
# 34 = blue
# 35 = magenta
# 36 = cyan
# 37 = white
# Background color codes:
# 40 = black
# 41 = red
# 42 = green
# 43 = yellow
# 44 = blue
# 45 = magenta
# 46 = cyan
# 47 = white

# Below are the color init strings for the file types. You can change
# these to suit your taste. The format is:
# filetype code;code;...;code
# where filetype is one of the following:
# NORMAL, FILE, DIR, LINK, MULTIHARDLINK, FIFO, SOCK, DOOR, BLK, CHR, ORPHAN, MISSING, EXEC, LEFT, RIGHT, END, SUID, SGID, STICKY, OTHER_WRITABLE, STICKY_OTHER_WRITABLE, CAPABILITY

# Normal file
NORMAL 00
# Directory
DIR 01;34
# Symbolic link
LINK 01;36
# Multi-hardlink
MULTIHARDLINK 00
# FIFO (named pipe)
FIFO 40;33
# Socket
SOCK 01;35
# Door
DOOR 01;35
# Block device
BLK 40;33;01
# Character device
CHR 40;33;01
# Orphaned symbolic link
ORPHAN 01;05;37;41
# Missing file
MISSING 01;05;37;41
# Executable file
EXEC 01;32
# Left code
LEFT 01;32
# Right code
RIGHT 01;32
# End code
END 01;32
# Setuid file
SUID 37;41
# Setgid file
SGID 30;43
# Sticky directory
STICKY 37;44
# Other writable directory
OTHER_WRITABLE 34;42
# Sticky and other writable directory
STICKY_OTHER_WRITABLE 30;42
# File with capability
CAPABILITY 30;41
