bash: __vte_prompt_command: command not found
Whenever I open a terminal, I am greeted with this line. Also, this is printed each time I enter a command in the terminal.
每当我打开终端时，都会看到这条线。此外，每次我在终端中输入命令时都会打印出来。
I am a linux-noob, and would be happy to read up, if someone can point me to some resource, or hint at a possible solution. I tried google-ing, but was unable to turn up with any useful results.
我是一个 linux-noob，如果有人可以指出我的一些资源或暗示可能的解决方案，我很乐意阅读。我尝试了 google-ing，但无法找到任何有用的结果。
I did not do anything specific just before this started popping up.
在这开始出现之前，我没有做任何具体的事情。
Thanks in advance :)
提前致谢 ：）

It sounds like a program named VTE has set your bash environment variable PROMPT_COMMANDto invoke a function called __vte_prompt_command.
听起来像是一个名为 VTE 的程序已将您的 bash 环境变量设置PROMPT_COMMAND为调用名为__vte_prompt_command.
The PROMPT_COMMANDenvironment variable defines a command that is executed before every new prompt is displayed to the screen. It can be veryannoying when this command produces unexpected output.
在PROMPT_COMMAND环境变量定义之前被显示到屏幕上的每个新的提示时执行的命令。当此命令产生意外输出时，可能会非常烦人。
You can temporarily get rid of the annoying messages by entering this command in the terminal:
您可以通过在终端中输入以下命令来暂时摆脱烦人的消息：
__vte_prompt_command() { true; }
This creates a dummy function that does nothing - you can confirm by looking at the output of this command:
这将创建一个什么都不做的虚拟函数 - 您可以通过查看此命令的输出来确认：
type __vte_prompt_command
After applying the hack to my system I see this:
将 hack 应用到我的系统后，我看到了这个：
__vte_prompt_command is a function
__vte_prompt_command ()
{
true
}
However, this is an indication that VTE may not be installed properly and/or may be broken. You might want to try to reinstall VTE, if possible. I would notrecommend putting this permanently into your ~/.bashrcfile.
但是，这表明 VTE 可能未正确安装和/或可能已损坏。如果可能，您可能想尝试重新安装 VTE。我不建议将其永久放入您的~/.bashrc文件中。

I am running Ubuntu 18.04 with the default gnome-terminal and ran into the same problem but wanted a definitive solution.
我正在使用默认的 gnome-terminal 运行 Ubuntu 18.04 并遇到同样的问题，但想要一个明确的解决方案。
After trying the solutions suggested previously, I still had the message:__vte_prompt_command: command not found
comming up after starting a new terminal and after each command terminated.
在尝试了之前建议的解决方案后，我仍然收到消息：__vte_prompt_command: command not found
在启动新终端后和每个命令终止后出现。
I searched for a file in for instance .bashrc, .profilethat would be doing a source /etc/profile.d/vte-2.91.shwith no luck.
Than I remembered that a long time ago I added the following line in my ~/.bashrc:
例如.bashrc，我在 中搜索了一个文件，.profile这将是source /etc/profile.d/vte-2.91.sh没有运气的。
比我记得很久以前我在我的中添加了以下行~/.bashrc：
export PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND$'\n'}history -a; history -c; history -r"
in order to append command line histories to all opened terminals. I figured out that commenting it solved the problem.
为了将命令行历史附加到所有打开的终端。我发现评论它解决了问题。
#export PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND$'\n'}history -a; history -c; history -r"
than$ source ~/.bashrc
比$ source ~/.bashrc
Thought I would share this for anyone having the same problem.
以为我会与任何有同样问题的人分享这个。

You can disable the corresponding code by editing your ~/.bashrcby using sudo gedit ~/.bashrc, searching for the string "vte"with STRG+F and outcommenting the line with a #.
On my system, the line looked like this, I guess an old installation of Ubuntu Budgie put it there:
您可以~/.bashrc通过使用编辑您的代码，使用STRG+Fsudo gedit ~/.bashrc搜索字符串“vte”并使用#. 在我的系统上，该行看起来像这样，我猜 Ubuntu Budgie 的旧安装将它放在那里：
if [ $TILIX_ID ] || [ $VTE_VERSION ] ; then source /etc/profile.d/vte.sh; fi # Ubuntu Budgie END
And if it looks like this, the line in your terminal will not appear anymore:
如果它看起来像这样，终端中的行将不再出现：
#if [ $TILIX_ID ] || [ $VTE_VERSION ] ; then source /etc/profile.d/vte.sh; fi # Ubuntu Budgie END
