我尝试在.bashrc中添加命令时找不到命令

Question

我问了一个关于如何在bash shell中编写一个漂亮优雅的linux命令的问题

当我尝试这个建议时,我收到以下错误消息.

Sorry, command-not-found has crashed! Please file a bug report at:
https://bugs.launchpad.net/command-not-found/+filebug
Please include the following information with the report:

command-not-found version: 0.3
Python version: 3.2.3 final 0
Distributor ID: Ubuntu
Description:    Ubuntu 12.10
Release:    12.10
Codename:   quantal
Exception information:

unsupported locale setting

  File "/usr/lib/python3.2/locale.py", line 541, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

这是我目前在.bashrc中编写的内容

source .bashrc
export LC_CTYPE="utf-8"
function go_app() { cd /var/virtual/$1/; }

这是我的/ var/www目录

www-data@ubuntu:~$ ls -la

编辑:

新的.bashrc

export LC_CTYPE="en_US.utf8"
function go_app() { cd /var/virtual/$1/; }

错误信息:

go_app: command not found

Answer 1

A bad WSL upgrade messed up some of my file permissions. None of the above things worked for me, but this did:

sudo chmod o+r /var/lib/command-not-found/commands.db

Answer 2

这应该修复"抱歉,命令未发现已崩溃!..."问题:

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
sudo dpkg-reconfigure locales

Answer 3

如果上述任何解决方案不起作用，则意味着“command-not-found”实用程序本身配置错误。

只需删除该实用程序，

sudo apt purge command-not-found

并再次安装，

sudo apt install command-not-found

Answer 4

您尝试过更改export LC_CTYPE="utf-8"为吗export LC_CTYPE="en_US.utf8"？后者引用了我的系统上的有效区域设置名称。您可以通过运行来查看系统上的有效区域设置名称locale -a。
