Bash导出：不是有效的标识符

我有一个树莓皮做的树莓皮。 默认情况下，shell以彩色格式显示自己，我想通过以下操作稍微更改这些设置，操作

LS\u COLORS

变量：

LS_COLORS="ow=01;90:di=01;90"
export LS_COLORS

当我通过ssh登录时会出现问题。在提示常规操作之前，它会显示以下内容：

-bash: export: `LS_COLORS:': not a valid identifier

我已经在

~/.bashrc

和

~/.bash_配置文件

中查找过了（实际上这个配置文件不存在）。 我没有在

.bashrc

中更改任何内容，也没有任何内容直接指向LS\u颜色。 我还尝试

$unset LS_COLORS

，但在下次登录时没有任何更改。 谢谢你的帮助

.bashrc

这条线看起来可疑：

test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)":

确定要在下线使用冒号？

检查脚本中的DOS行结尾。我怀疑你实际上是在尝试导出

LS\u颜色\r

。你在某个地方有

LS\u颜色：

——你有一个共同的想法去哪里找？你可以在树莓PI上的主目录中运行

grep'LS\u颜色：'~/.

，试图找到报告的错误发生的地方。请发布

~/.bashrc

的内容这一行和整个

.bashrc

文件都是Raspbian附带的原始文件。我没有编辑任何这些。
