[Solved] ERROR o.s.s.s.TaskUtils$LoggingErrorHandler – Unexpected error occurred in scheduled task.

When this error occurs, we should look at the following error message. Only this error is meaningless. What I see here is a java.lang.NoSuchMethodError. This error tells us that the method does not exist. The reason for this error may be that the package has not been introduced, or it may be a version conflict, resulting in the method not being found.

But the errors you may make are not like this, so you can search like this:

java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;I)

Today, adding Swagger2 to the project resulted in an error during project operation:

UE5 C:\Program Files\Microsoft Visual Studio\2022\Enterprise\MSBuild\Microsoft\VC\v170\Microsoft.MakeFile.Targets 44

 

Cause:
The problem occurs in the MSVC compiler (14.32.31326:MSVC v143-VS 2022 C++v14.32-17.2)
Visual Studio 2022 17.3.3 latest version, version too high

{
thrownew BuildException($”Dependency file “{InputFile.Location}” version (“{Version} “) is not supported version”);
}

Solution:
Use the following version of MSVC compiler and recompile it.
14.29.30133: MSVC v142 – VS 2019 C++ v14.29-16.11
14.30.30705: MSVC v143 – VS 2022 C++ v14.30-17.0

[Solved] This dependency was not found: * core-js/modules/es.error.cause.js in ./node_modules/@babel

[Error] This dependency was not found: * core-js/modules/es.error.cause. js in ./node_ modules/@babel/runtime

Solution: Delete the node_modules folder directly in the project folder, then install core-js in the terminal

npm install --save core-js

After installation, continue to run the following command

npm install

Start project:

npm run dev

The project is ready to run

Vite2.x upgrade Vite3.x error reported this message

Solution:

In addition to upgrading Vite itself, it is best to upgrade all plugins involved in Vite in package.json devDependencies development dependencies, such as @vitejs/plugin-vue, @vitejs/plugin-legacy, etc.

If not yet solved, try to upgrade the plugins corresponding to Vite involving eslint and so on.

[Solved] Rstudio Error: Error in `vec_as_location()`: `…` must be empty.

In the process of running the dplyr package installation, you may be prompted with this error, and you can install it again

Error in `vec_as_location()`:
! `...` must be empty.

Run `rlang::last_error()` to see where the error occurred.

Solutions

install.packages("dplyr")

[Solved] ERROR: Could not open requirements file: [Errno 2] No such file or directory : ‘requirments.txt‘

After checking the relevant information, I found out that this is actually a path setting problem. It is that your text actually exists, but the path you set is not correct causing the system to not find the requriements.txt file.

So, you just need to change your path setting to the path of the parent file you want to query.

I use the cmd system command cd to enter the specified file and then pip install -r requirments.txt method.

Example.

If requirements.txt is under the PythonProject file, then use

Cd C:\Users\xizhou\Desktop\PythonProject # Enter superior files first

pip install -r requirements.txt # Install pip again

The file can then be found.

[Solved] qrcode-error: Exception in thread “main” java.lang.NoClassDefFoundError…

qrcode-error

Project scenario:

QR code generation

Problem description

Hint: Here we describe the problems encountered in the project:

For example, in the process of data transmission, data is lost from time to time, and some data is occasionally lost
The code of data received in the APP:

QrConfig qrConfig = QrConfig.create(); 
qrConfig.setWidth(500);
qrConfig.setHeight(500); 
String encode = Base64.encode(QrCodeUtil.generatePng("loginQRVerify:",qrConfig));

Cause analysis:

Prompt: jar package is missing

Solution:

sqlite plus Error parsing time stamp [How to Solve]

Using datetime type will report error parsing time stamp

Caused by: java.sql.SQLException: Error parsing time stamp
Caused by: java.text.ParseException: Unparseable date: “2021-08-10 09:27:10” does not match (\p{Nd}++)\Q-\E(\p{Nd}++)\Q-\E(\p{Nd}++)\Q \E(\p{Nd}++)\Q:\E(\p{Nd}++)\Q:\E(\p{Nd}++)\Q.\E(\p{Nd}++)

Preemptive solution
Modify the time format of the driver in the configuration file, URL passing reference (recommended)
jdbcUrl=jdbc:sqlite:test_name.db?date_string_format=yyyy-MM-dd HH:mm:ss

	 /**
	 * Sorting files by file date
	 * File[] dbFiles = SqlteUtils.orderByDate(dataFilePath);
	 * @param fliePath
	 * @return
	 */
	public static File[] orderByDate(String fliePath) {
		File file = new File(fliePath);
		if (!file.exists()) {
			file.mkdirs();
		}
		File[] fs = file.listFiles();
		Arrays.sort(fs, new Comparator<File>() {
			@Override
			public int compare(File f1, File f2) {
				long diff = f2.lastModified() - f1.lastModified();
				if (diff > 0) {
					return 1;
				} else if (diff == 0) {
					return 0;
				} else {
					return -1;
				}
			}
			@Override
			public boolean equals(Object obj) {

Solution:

1. View log

# cat config.log |grep error
gcc: error: unrecognized command line option '-V'
gcc: fatal error: no input files
gcc: error: unrecognized command line option '-qversion'
gcc: fatal error: no input files

Missing libmpfr.so.4 File

2. Install mpfr

Package name:mpfr-3.1.1-4.el7.x86_64

~# yum install mpfr-3.1.1-4.el7.x86_64 -y
......
Verification:
~# ll /usr/lib64/libmpfr.so.4
libmpfr.so.4      libmpfr.so.4.1.1  
~# ll /usr/lib64/libmpfr.so.4
lrwxrwxrwx 1 root root 16 Sep  7 22:26 /usr/lib64/libmpfr.so.4 -> libmpfr.so.4.1.1

Finally, the problem is solved

[Solved] Error: error C2601: ‘b‘ : local function definitions are illegal error C2063: ‘b‘ : not a function

Scene:

In general, this problem may be that a "}" is missing
There is also a small probability that your C++standard library is C++98 or earlier, which does not support non built-in initialization list writing.

the Situation of Missing ‘}’

We can see that if our test1 method is short of one}, all subsequent functions will report errors. We need to check it carefully

Solution
Check for yourself that the first line of code near the line number that reports the error is missing a }.

C++ standard does not support
When your C++ standard is C++98, the initialization list of C++98 does not support the initialization list methods of non-built-in types. This can be seen in the following code

#include <iostream>
#include <vector>
#include <map>
using namespace std;

int main()
{
	int a[] = { 1, 2, 3 };

	int b[] {1, 2, 3};
	vector<int> v{1,5,5};
	map<int, float> m{{1, 2.f}, {2, 3.2f}};

	return 0;
}

编译结果：

Solution:
Then in this case your non-built-in type variables will have to be initialized using other methods

[Solved]Error:java: Compilation failed: internal java compiler error

When you use Idea to import a new project or upgrade an idea or create a new project, the following exception information appears:

Error:java: Compilation failed: internal java compiler error

This error is mainly caused by the jdk version. There are two reasons: the compiled version does not match, and the current project jdk version does not support it.

Solution:

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

[Solved] Python sqlite3.OperationalError: near “?“: syntax error

code

con = sqlite3.connect('db.sqlite3')
cur = con.cursor()
sql = 'SELECT id FROM ?WHERE source_id = ?'
cur.execute(sql, ('article_table', 41945,))
one = cur.fetchone()
con.close()

report errors

sqlite3.OperationalError: near "?": syntax error

reason

sqlite3 placeholder (?) Cannot be used for column or table names.
Placeholders are used to insert or retrieve values of data from the database in order to prevent SQL injection.

Solution:

con = sqlite3.connect('db.sqlite3')
cur = con.cursor()
sql = 'SELECT id FROM article_table WHERE source_id = ?'
cur.execute(sql, (41945,))
one = cur.fetchone()
con.close()
