In Vue projects, you need to reference third-party libraries, such as vant@^2.12.47. When using the dialog popup component, you need to use v-model:show to determine whether to display the popup.
When the project is running, an error will be reported: error ‘v-model’ directives require no argument vue/valid-v-model
Solution: Add:'vue/valid-v-model':'off' in the root directory, .eslintrc.js file.
As shown in the figure:
Error message:
org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project.MavenProject, org.apache.maven.archiver.MavenArchiveConfiguration)
Solution:
Add and change the following plugin configuration in pom:
</plugin>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.6</version>
</plugin> 1. Occurrence scenario
thinkphp framework using phpoffice/phpexcel, exporting Excel tables directly to the browser for download, the error is reported: ERR_INVALID_RESPONSE
2. Find a solution
1. Online solutions
1) Buffer problem
calling ob_clean() before calling save（“ php://output "), part of the code is as follows:
ob_clean(); //Emptying the cache
// final output via browser
$fn = "The name of the file (" . date("Y.m.d") . ").xls"; // the name of the file to be saved
header('Content-Type: application/vnd.ms-excel; charset=utf-8');
header("Content-Disposition: attachment;filename={$fn}");
header('Cache-Control: max-age=0');
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;
2) Error is reported in line 581 of factory581, and break is deleted
Error in factory581 line, delete break;
PHPExcel\Calculation\Functions.php file, remove break at line 581
our phoffice/phpexcel is installed by composer. We have to change the source code every time we update it. It is not recommended to modify the source code. Even if it can solve the problem, it will not be adopted
2. My solution to this problem is to install the zip extension under Linux
[solution] my problem is that Linux lacks the zip extension. You can install it~
3. Zip extension
PHP under windows (my version is 7.3.3) has its own zip extension, and there is no directory_zip.dll file under the php/ext path, as shown in the figure
PHP under Linux does not have zip extension installed
Check /home/admin/canal-server/logs/example/example.log and find the following error:

at com.alibaba.otter.canal.parse.inbound.AbstractEventParser$1.run(AbstractEventParser.java:262)
at java.lang.Thread.run(Thread.java:748) reason:
The binlog file set in the configuration file was not found
Solution:
Because the configuration file of instance.properties is packaged into the docker image, so it can only be modified in the instance
First check the binlog log file name and position in the database
Query in the mall-mysql database of this example:
mysql> show master status;Output file: File: mysql-binlog.000233, Position: 652645
Enter the instance:
kubectl exec -ti mall-canal-84f6f7d7cc-xbghn bash -n nsName
xxx> vi /home/admin/canal-server/conf/example/instance.propertiesModify the position Info section:
canal.instance.master.address=mall-mysql:3306
canal.instance.master.journal.name=mysql-binlog.000233
canal.instance.master.position=652645
canal.instance.master.timestamp=
canal.instance.master.gtid=Restart service:
xxx> cd /home/admin/canal-server
xxx> ./restart.shCheck the log after restart and solve this error.
Start the error report after packaging with electron-builder:

Solution:
1. Execute the following command:
npm install vue-devtools --global
2. Modify src/main/index.dev.js as follows:
import { BrowserWindow } from 'electron'; //Add
/* eslint-disable */
// Install `electron-debug` with `devtron`
// require('electron-debug')({ showDevTools: true })
require('electron-debug')() //Modify
// Install `vue-devtools`
require('electron').app.on('ready', () => {
let installExtension = require('electron-devtools-installer')
//Comment out
// installExtension.default(installExtension.VUEJS_DEVTOOLS)
// .then(() => {})
// .catch(err => {
// console.log('Unable to install `vue-devtools`: \n', err)
// })
//Add
BrowserWindow.addDevToolsExtension('node_modules/vue-devtools/vender')
})
// Require `main` process to boot app
require('./index')
3. Recompile:
npm run build:win32
4. Repackage:
electron-builder
It can start normally:
I had tried many solutions online. but they do not work. here is my working solution I found finally.
Solution:
1. First, make sure that ADB devices can query your device
2. Key solution: delete ATX on the mobile phone and re-execute python -m uiautomator2 init
3. Just in case, don’t directly execute the WebEditor. Be sure to execute python -m weditor
Then click Dump Hierarchy to synchronize the screen. Don’t use real-time, just use static.

Delete the NumberInfo folder under the components folder, start the project again, and after starting, Ctrl + z to withdraw the deleted NumberInfo component folder, after which the project will start normally
Solution:
1. Delete, yarn run serve to start project
2. Withdrawal
3. Project started successfully
After android9.0, WebView can’t load the link starting with HTTP, or an error is reported.
Solution:
1. Add android:usesCleartextTraffic = true in the Application tag of AndroidManifest;
2. Set in webclient
webView.webViewClient = object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
if (url.startsWith("http://") || url.startsWith("https://")) {
webView.loadUrl(url)
return true
}
return true
}
}Error: pymysql.err OperationalError: (1045, “Access denied for user ‘root’@‘192.168.118.44’ (using password: YES)”)
Possible problems:
1. Firewall blocking,
Solution: log in to the server and turn off the firewall
systemctl stop firewalld.service
2. User empowerment (the root user I use here)
Solution: log in to the MySQL database for empowerment
grant all privileges on *.* to 'root'@'%' identified by 'password';
flush privileges;
3. Check whether the password is entered incorrectly

1. Background
Unity project has the following capabilities
1. It can run directly on Android phones
2. You can build an APK file and then install it on the mobile phone to run
3. It can be packaged into an Android project and run the project using Android studio
There may be no problem that 1 and 2 can be implemented normally, but an error will be reported when implementing the third method
the first error:
unity UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&) (at /Users/bokken/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:189)
the second error:
UnityEditor.BuildPlayerWindow Error
2. Precautions
1. There is no problem with the configuration of gradle environment, because it can be compiled normally
2. The package directory also has no Chinese name
3. There is no problem with the packaging configuration
3. Solutions
Exporting Android Studio project needs to be consistent with our project name of unity
For example: File-BuildSettins-PlayerSetting-Player-ProductName name and File-BuildSettins-Build file directory name consistent can be solved
1. Development environment
redis
2. Redis reports an error: NOAUTH Authentication required.
1. Set your password and open redis.window.conf file, search requirepass to view your password
2. For those without a password, there is a situation that can cause this error. Redis is running in the background. End redis in the background of the task manager and restart it
