Vscode Katex Error: ParseError: KaTeX Parse Error: Can‘t Use Function ‘$‘ In Math Mode At Position …
Problem description
When doing Wu Enda’s deep learning, KAtex is prompted with parsing errors. A pile of KAtex plug-ins under vscode are useless. The errors are as follows:
parseError: KAtex parse error: can't use function '$' in math mode at position
Solution:
Strange solution, in the following figure, call back
Problem solved
Solution:
First press the shortcut key to open Ctrl + P or Ctrl + Shift + P
Find settings.json file and open it:
Then enter the following code configuration
{
"python.jediEnabled": false,
"terminal.integrated.shell.windows": "C:\\Windows\\sysnative\\cmd.exe"
}
Finally, restart directly
1. preface
After using vscode to install the plug-in: glsl lint, there is an error every time you start vscode:
glsl lint: failed to spawn ‘glslangvalidator’ binary Error: spawn glslangValidator. Exe enoent
and vscode will not be automatically colored and highlighted every time the shader program is opened. At this time, I reinstall the glsl lint plug-in. It’s troublesome
glslangValidator is a custom GLSL reference compiler from the Khronos Group, the official OpenGL standard customizer. The command line compilation mode facilitates users to test glsl syntax directly and bypass the C/C++ related dependency libraries compilation, and there is no need to write a lot of initialization code in the main file. This can save a lot of time in practical testing. In many websites such as shadertoy, the glsl code written by users can be compiled and run directly in the main function, which requires a convenient syntax check, and the shadertoy website also provides a simple syntax check. However, glslang is a standard custom official compiler, so the compiled glsl code can be compiled correctly on all kinds of drivers that support GLSL syntax.
2. Solution steps
1. Open vscode settings
2. Search “security.workspace.trust”
Enter “security.workspace.trust” in “search settings” (just enter “security”)
3. Cancel ssecurity.workspace.trust：Enabled
Remove the hook in front of “security.workspace.trust：Enabled”
Just restart vscode
Use/deep/to report syntax errors in vscode and report them in red
When pulling other people’s items, you will encounter/deep/reporting syntax errors in vscode, but the items can run and we can’t modify them. The problem can be solved by modifying the configuration file of vscode
CSS> Lint: empty rules
then there is no red wavy line and no error is reported
Cause
After the extension is successfully installed, the file upload prompt error: no such file
but the code has actually been uploaded successfully**
Solution:
Open ~ /.Vscode/extensions/liximomo.sftp-1.12.9/node_modules/ssh2streams/lib/sftp.js
search
options.emitClose= false;
Add under each search term
options.autoDestroy = false;
Remember to restart vscode for the changes to take effect.
Code screenshot
Recently, I learned the C + + program video of dark horse. When I realized the employee management system based on polymorphism, I knocked the same code as the video, but I couldn’t compile it successfully by using vscode, and the following errors occurred:
[Employee_Management_System.cpp 2021-10-22 13:58:17.099]
,,C:\Users\AAE3~1\AppData\Local\Temp\cc7ZdaG7.o:Employee_Management_System.cpp:(.text+0x1b): undefined reference to `WorkerManager::WorkerManager()'

collect2.exe: error: ld returned 1 exit status
After querying many blogs, it is found that the causes and solutions of errors such as collect.exe: error: 1D returned 1 exit status are as follows
1. The last compiled program is not closed, that is, the black box still exists. Find it and close or restart the IDE
2. The program has no main function or the main function is misspelled
3. Running in vscode will not help you save the code. You need to save the code before running
4. The file name and file path may cause errors in some compilers
5. There is an undefined reference. This is the case for this error. When instantiating the classes of other files in the main function, you need to define the .H file and .Cpp file of other classes to solve the problem.
#include<iostream>
#include"workerManager.h"
#include"workerManager.cpp"
1. Cause
A new configuration file of vetur.config.js is added in vetur 0.31.0.
after this version, priority will be given to finding whether the project is equipped with tsconfig.json (TS project) or jsconfig.json (JS project).
if these two files are not found, go to vetur.config.js. If they are not found, this prompt will be thrown.
2. Explain
The JavaScript support of vscode can run in two different modes:
file range (without jsconfig.JSON)
in this mode, JavaScript files opened in vscode are regarded as independent units
as long as the file A.js does not explicitly reference the file b.ts (using// reference instructions or commonjs modules), there is no common project context between the two files.
3. Explicit project
(use jsconfig.JSON)
The JavaScript project is defined through the jsconfig.JSON file. The existence of such a file in the directory indicates that the directory is the root directory of the JavaScript project
the file itself can optionally list files belonging to the project, files to be excluded from the project, and compiler options (see below)
the JavaScript experience improves when you have a jsconfig.json file in your workspace that defines the project context
therefore, when you open a JavaScript file in a new workspace, we provide a prompt to create a jsconfig.json file.
4. Solution (1 out of 3)
"vetur.ignoreProjectWarning": true,
Add code:
{
"include": [
"./src/*"
]
}
Add code:
module.exports = {
// vetur configuration, which will override the settings in vscode. default: `{}`
settings: {
"vetur.useWorkspaceDependencies": true,
"vetur.experimental.templateInterpolationService": true
},
// Normal projects use the default configuration default: `[{ root: './' }]`
}
This is because vs code will not be saved automatically after you click Run. You need to save it by Ctrl + S
if it is not saved, a dot will be displayed
Suppose you have made the following configuration and try
so you start trying to connect to the server. After selecting Linux/windows from the top drop-down menu, you unfortunately fail
Error message:
After the popup window of could not establish connection to “XXX” appears, check the error information below. If the error information contains:

in config file, and try to connect again. It is found that the connection is successful
Today, when using remote SSH of visual studio code to connect remotely, the following problems appear:
(Error: Handler already set!)

Today, when using Visual Studio code to delete some characters with keyboard back, we found the following error:
command 'markdown.extension.onBackspaceKey' not found
It seems that it is caused by some shortcut key conflicts
Solution:
Open file – > preferences – > keyboard shortcut and search back, as shown in the figure below:
Just reset a shortcut key for this option:
