好的 再次谢谢李老师，其实Windows已经下了paraview就是更改bashrc文件让linux能调用的时候也出错了，只能复制粘贴文件太麻烦了。没事 改天我再重下次！

用的wsl安装的Ubuntu，gedit确实打不开

yl@yl:~$ sudo gedit ~/.bashrc
sudo: gedit: command not found

谢谢两位老师的回答，我的是ubuntu20.04.6LTS,qt应该是有的，我又根据网上的教程查了查，发现还是无法打开，具体如下：qmake --version后显示

QMake version 3.1
Using Qt version 5.12.8 in /usr/lib/x86_64-linux-gnu

export QT_DEBUG_PLUGINS=1后还是报错

Got keys from plugin meta data ("xcb")

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted

然后又查了依赖

 ldd /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so

依赖也没有缺少的，但是依然打不开。

各位前辈大佬们，我在安装后ofv2206后发现paraview打不开，遂apt install paraview，但在使用时报错显示无法显示，如下，根据网上搜索到的问题也进行了修改，但还是不行

yl@yl:~$ paraview
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted

后又想着使用paraFoam,于是重新编译成功了paraFoam后，输入命令，还是无法打开，代码如下：

 yl@yl:~$ paraFoam
-bash: /home/yl/OpenFOAM/v2206/OpenFOAM-v2206/bin/paraFoam: /bin/sh^M: bad interpreter: No such file or directory

请教各位前辈们，这应该怎么解决呀？
