[Solved] Vue3 Error: Unhandled error during execution of scheduler flush. This is likely a Vue internals bug. P

Unhandled error during execution of scheduler flush. This is likely a Vue internals bug. Please open an issue at https://new-issue.vuejs.org/?repo=vuejs/vue -next

Error reason

An error is reported when vue2 turns to vue3

Error reporting reason

Nested functions are used in the way of global variables. When functions are executed, errors are reported and vue3 direct errors are reported

Check the error position

On the page with problems, correct the errors by commenting the code and quickly find the error location

Solution

The code in the function is written correctly

No error reported!

Leetcode error: AddressSanitizer:DEADLYSIGNAL [How to Solve]

leetcode error:

AddressSanitizer:DEADLYSIGNAL ================================================================= ==43==ERROR: AddressSanitizer: SEGV on unknown address (pc 0x00000034ca17 bp 0x7ffe82f08070 sp 0x7ffe82f07f40 T0) ==43==The signal is caused by a READ memory access. ==43==Hint: this fault was caused by a dereference of a high value address (see register values below). Dissassemble the provided pc to learn which register was used. #3 0x7f952a7800b2 (/lib/x86_64-linux-gnu/libc.so.6+0x270b2) AddressSanitizer can not provide additional info. ==43==ABORTING

As you can see, the unknown address was accessed.
Reason:
The code accesses the top element of the stack for an empty stack

else if(s[i] == '}')
{
    if(st.top() == '{')
    {
       st.pop();
    }else
    {
       return false;
    }
}

Solution:

Just join the blank judgment

else if(s[i] == '}')
{
    if(!st.empty() && st.top() == '{')
    {
        st.pop();
    }else
    {
        return false;
    }
}

[Solved] ERROR SparkContext: Error initializing SparkContext. java.lang.IllegalArgumentException: System memo

During the actual operation of the recommendation system, the following errors occur when executing the featureengineering (Scala) file:
ERROR SparkContext: Error initializing SparkContext. java.lang.IllegalArgumentException: System memory 259522560 must be at least 471859200

Solution:
1. Click Edit configurations

2 If your setting interface has the following red box, paste the following text directly

-Xms128m -Xms512m -XX:MaxPermSize=300m -ea


3. If not, click Modify options first, then add VM options, as shown in the figure below, and then complete the second step

this problem should be solved.

Problem Description:

Here are: error parsing SQL mapper configuration, error parsing mapper XML and type typeexception: unable to resolve type alias “order”.

Cause analysis:

Unable to resolve type name ‘ order ‘, please see

sqlMapConfig.xml. It is found that the custom name order is omitted

Solution:

<!--Add a custom name-->
    <typeAliases>
        <typeAlias type="com.itrs.domain.User" alias="user"></typeAlias>
        <typeAlias type="com.itrs.domain.Order" alias="order"></typeAlias>
    </typeAliases>

Add a custom name to solve the problem

[Solved] Springboot project Create to start Error: APPLICATION FAILED TO START

 

Description:
Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
Process finished with exit code 1

Reason:
Spring boot loads the org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration class by default, after introducing mybatis-spring-boot-starter in the pom. DataSourceAutoConfiguration class uses the @Configuration annotation to inject the dataSource bean into spring because there is no configuration information about the dataSource in the project, so when spring creates the dataSource bean due to the lack of relevant information it will report an error.

Solution:
Add attribute @SpringBootApplication(exclude = DataSourceAutoConfiguration.class) to the Spring boot boot boot class to prevent Spring boot from automatically injecting the dataSource
