IOS Adds C File Error [How to Solve]

Reason: This is actually the logic of using pch files in Xcode compilation, after introducing c files in the project, pch will mix #include and #import, in order to reduce compiler workload, you need to use precompiled macros to make a slight distinction.

Solution: Check all pch files in the project and put “#import xxx”, which is only used in OC, in “#indef __OBJC__” and “#endif”

#ifndef PrefixHeader_pch
#define PrefixHeader_pch

#ifdef __OBJC__

#import "Masonry.h"

#endif


#endif /* PrefixHeader_pch */

How to Solve Svn upload so File Error

Cause of the problem: since the so file is a binary file, it is ignored by default. You need to modify the configuration before uploading

Solution:

find   / -name .subversion # find SVN configuration file path

cd to find the path of .subversion

VIM config finds these two lines:

#global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *pyo

#  *.rej *~#*# .#* .*.swp.DS_Store

Modified as:

###global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *pyo

###  *.rej *~#*# .#* .*.swp.DS_Store

global-ignores = .*.swp.DS_Store

It can be solved after saving!

How to Solve npm-install Command -4048 Error

When I reinstall the computer system, I download the front-end environment configuration again. An error occurs when configuring NPM. The main error messages are as follows:

npm WARN logfile could not create logs-dir: Error: EPERM: operation not permitted, mkdir 'E:\work\node\node_cache\_logs'

First, check whether the parameters of system environment configuration and user environment configuration are consistent

Click the path in the system environment configuration to observe whether the path is consistent. This may be my personal reason. After reinstalling node several times, the path here is inconsistent. After the change, it is still not possible.

I thought it was caused by the command line permission problem, and found that using the administrator still does not work, and then I searched the Internet for the reason and finally found it;

  1. Find the .npmrc file under C:\Users\{account}\ and delete it
  2. After clearing npm cache:npm cache clean –force
  3. Then run the npm install command.

How to Solve wikiextractor Extract Wikipedia Corpus Error

When I extracted Wikipedia corpus, I first used the wikiextractor. Later, I found that it was always wrong, so it was useless. Since many people asked me how to extract the corpus, I now publish the code

I didn’t write the code, but I found it from a website. Because it took too long and I forgot the address of the website, I can’t post the original URL. If the author sees it, please send a private letter to my original URL

The author’s email address is: [email protected]

How to use: enter the command at the command line:

Use version information

  • SpringBoot 2.7.3
  • springfox-boot-starter 3.0.0

Use the above version of the dependency package for integration, start the service, and directly report the previous error. It is preliminarily determined that the problem should be caused by the version.

Cause:

After springboot 2.6.0, the default path matching policy of spring MVC was changed from AntPathMatcher to PathPatternParser, resulting in an error in starting the service.

Solution:

Add the following line of configuration information to the application.properties configuration file to solve the problem

#How to Solve swagger error
spring.mvc.pathmatch.matching-strategy=ant_path_matcher

[Solved] Nacos1.3.2 Startup Error: Unable to start embedded Tomcat

Recently, I started to plan to learn springcloud-alibaba, so I downloaded the Nacos installation package on the GitHub official website, and found an error on startup.

Error message: Unable to start embedded Tomcat
the built-in Tomcat cannot be loaded.

Opened the conf folder and saw a nacos-mysql.sql
It seems to import a database script, so I created a database named nacos in the local database
and executed this sql script, which generated some tables.

With a database and tables, we must change the configuration.
So I opened application.properties with an editor
I saw that there is a place to configure the db, so I changed it.

After saving
enter the bin directory again and double-click startbat.cmd to start.

I found that I still reported an error.


Caused by: java.net.UnknownHostException: jmenv.tbsite.net

Here I have changed the configuration file again, but it has no effect.

The key point is that during startup, I noticed a message,
Nacos has been started in cluster mode. Cluster list is []

I wonder if this is the problem, because I clicked run and did not configure the Nacos cluster.

So I use the editor to open the startup.cmd in the dictory bin
see a key message

Here you can configure click mode startup, so try to change the startup configuration to click mode startup

Exit after saving. Double click the startup file startup.cmd

It started normally this time.

Enter in Browser: localhost:8848/nacos/index.html

Normally access the Nacos configuration center.

[Solved] Idea Failed to recognize Maven and Project Error

All the data packages of the open project are red, and the startup reports an error. Don’t panic when you encounter such a situation.

(this is only useful for the downloaded jar package project. If the project is newly opened, you need to download the Maven file)

click File in idea > Invalideate Caches…/restart clear cache and restart

Clear and restart the project

Solution: The introduction of both Mybatis and Mybatis-plus into the dependency will cause a conflict, either one. In addition to noticing if there is a conflict in the pom file of this module, we also need to see if the parent module of this module has already introduced the mybaits dependency and you later introduce the Mybatis-plus module in this module, causing a conflict. This scenario is more insidious and not easy to detect.

Solution:

1. First, see if the annotation on the Service layer class is added or wrong, it should be @Service, whether the annotation refers to the Spring class, do not import it into another package, and see the path of the package.

2. Also, if the Service layer is divided into interfaces and implementation classes, see if the implementation class is annotated (@Service), and see if there is an implementation class.

3. Take a look at the configuration file. xml, is there any package where the automatic scan service is started?

<context:component-scan base-package="com.liglei.service"></context:component-scan>

4. Check if the jar package is downloaded completely and if there is this jar package

5. Just to see if there are any packages in the red box in the figure below that have not been imported, and if so, follow the steps below:

File–> Project Structure–> Artifacts–> Right click demopage –> Put into Output Root–> OK

Make sure the above steps are OK. Restart the project and try again~

How to Solve SpringBoot MongoDB MongoAutoConfiguration Startup Error

Background

SpringBoot project needs to manually control whether to load MongoDB auto-configuration (i.e.: MongoAutoConfiguration), then startup error

- Bean method 'mongoTemplate' in 'MongoDatabaseFactoryDependentConfiguration' not loaded because @ConditionalOnBean (types: org.springframework.data.mongodb.MongoDatabaseFactory; SearchStrategy: all) did not find any beans of type org.springframework.data.mongodb.MongoDatabaseFactory

code:

@Import(value = {MongoDataAutoConfiguration.class, MongoAutoConfiguration.class})

Solution: Replace @Import content order, load MongoAutoConfiguration first

@Import(value = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})

How to Solve Hyperf Failed to Start Error After Aliyun ACM Installed

Today, try installing the hyperf microservice framework

Alibaba cloud ACM is selected when installing the service

The console keeps making such mistakes

[ERROR] Client error: `GET http://139.196.135.144:8080/diamond-server/config.co?tenant=&dataId=&group=DEFAULT_GROUP` resulted in a `404 Not Found` response:
config data not exist

[line:113] in /www/hyperf/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php

Solution:

Modify the configuration in hyperf/config/autoload/config_center.php in the project root directory

return [
    'enable' => (bool) env('CONFIG_CENTER_ENABLE', false), // set to false
    'driver' => env('CONFIG_CENTER_DRIVER', 'aliyun_acm'),
    'mode' => env('CONFIG_CENTER_MODE', Mode::PROCESS),
    'drivers' => [
        'aliyun_acm' => [
            'driver' => Hyperf\ConfigAliyunAcm\AliyunAcmDriver::class,
            'interval' => 5,
            'endpoint' => env('ALIYUN_ACM_ENDPOINT', 'acm.aliyun.com'),
            'namespace' => env('ALIYUN_ACM_NAMESPACE', ''),
            'data_id' => env('ALIYUN_ACM_DATA_ID', ''),
            'group' => env('ALIYUN_ACM_GROUP', 'DEFAULT_GROUP'),
            'access_key' => env('ALIYUN_ACM_AK', ''),
            'secret_key' => env('ALIYUN_ACM_SK', ''),
            'ecs_ram_role' => env('ALIYUN_ACM_RAM_ROLE', ''),
        ],
    ],
];

Or the zone applies for Alibaba cloud ACM, and it is OK to fill in the relevant configuration successfully. It is recommended to close it in the development stage
