reported this error today while creating a new VUE project. It has been checked many times online, but there is no effective solution.
Then after many runs, suddenly found that it worked

Vue cli service: command not found

}
First remove the node - the module
and reinstall the NPM install
Node.js Medium package.json The difference between devdependences and dependencies
- devDependencies The dependencies user releases the environment and generates the required dependencies. The NPM install parameters — save and — save-dev — save-dev download plug-ins in the dependencies of package.json file devdPendencies
NPM run dev error: cannot find module ‘webpack cli / bin / config yargs‘
"devDependencies": {
"webpack": "^5.2.0",
"webpack-cli": "^4.1.0",
"webpack-dev-server": "^3.11.0"
}Webpack-cli: “^4.1.0”, which is version 4.*
2- Uninstall the current webpack-cli directive: NPM uninstall webpack-cli
3.* version directive: NPM install [email protected] -d
Just run NPM run dev!

Because process 0 is a system process, executing “Taskkill/PID 0” will not kill it. So, find another way to change the port, as follows:
Under node’s installation root, find package.json, search 8000, and replace with 8888
Then execute the command NPM Start from the command line, and it starts successfully
Enter it in the browser
http://localhost:8888

On and off of timer in JS
setInterval()
When a function
is called for a specified period of time:
setInterval(function,time,lang)
function: function to be called or code string to be executed
time: required parameters, every how long to call the function, in milliseconds
lang: optional parameters, running JScript | VBScript | JavaScript
clearInterval()
Means to stop the setInterval timer call function
function getTime() {
console.log(123);
if (true) {
clearInterval(db)
}
}
let db = setInterval(getTime, 1000)
setTimeout()
Call a function after a certain time
syntax:
setTimeout(function,time,lang)
Function:
function: required, to be called
time: required, number of milliseconds to wait before executing code
lang: optional, script language: JScript | VBScript | JavaScript

Solutions:
Just execute the command “NPM install” in the corresponding application directory, as shown in the figure below:
Before the above operation, the command “NPM install -g Express” was also executed, I wonder if it has any effect, as shown in the figure below:

Valentine’s Day is the day when the mistress and the principal room rob a man, the day when the underground party rises to the surface, the day when the rose appreciates, and the day when the living are created! At 4 p.m., the florist smiled; At six o ‘clock in the evening, the owner of the restaurant smiled; At 9 p.m., the nightclub manager smiled; Midnight, the hotel owner smiled; The next day, the drugstore owner smiled; A month later, the gynecological hospital doctors and nurses all smiled.
