when using make menuconfig to configure Linux corl error: target ‘menuconfig’ failed to recipe.
Solution:
1. Check whether the libncurses5-dev library is installed
If it’s not installed, install with the command: sudo apt-get install libncurses5-dev
2. If it’s installed, it’s because the terminal window is too small. It’s solved by enlarging the window
ERROR: [2] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
Reason: Generally, you can check whether the following nodes are present in the elastic.yaml configuration file in the es installation directory
elsearch soft nofile 65536
elsearch hard nofile 65536
If not, then you need to configure it, and replace the elsearch with your own server user.
There is also a possibility that the above error is still reported even though the server has been configured, possibly due to the fact that the current logged-in user has not synchronized the configuration due to a server reboot.
Use su ~ xx to re-login to solve the problem.
error messages:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
Exception in thread "main"redis.clients.jedis.exceptions.JedisConnectionException: Failed to create socket.
java.net.SocketTimeoutException: connect timed out
Reason: Unable to load class “org . slf4j . impl . staticloggerbinder”, no operation (NOP) logger implementation by default, cannot create socket, resulting in connection timeout.
Solution:
Step 1: add import dependency first (because a class cannot be loaded, it means that there is no dependency in the library, so it needs to import dependency)

Step 2: Comment out bind 127.0.0.1 on line 69 of the redis.conf configuration file. Commenting out bind 127.0.0.1 means that all client access is available, which is equivalent to bind 0.0.0.0
Step 3: Change yes to no in protected-mode yes on line 88
Step 4: Kill the redis process and restart it
ps -ef |grep redis
kill the redis process port number

redis-cli -p 6379
Step 5: Connecting to Redis in idea by manipulating jedis
finally successful:
Title SecureCRT login ubuntu20.04 prompt “key exchange failed” error
When using ubuntu2004, an error will be reported when using the old version of SecureCRT to connect via SSH, as follows:
Key exchange failed.
No compatible key exchange method. The server supports these methods: curve25519-sha256,[email protected],ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256
To solve this problem, the solution is as follows:
1. Modify ssh_config
Find the following two lines in this file and remove the # in front of them
vim /etc/ssh/ssh_config
2. modify sshd_config
vim /etc/ssh/sshd_config
KexAlgorithms [email protected],ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1
3. Restart sshd service
systemctl restart sshd
<template>
<component
ref="formComponent"
:is="formComponent"
/>
</template>
<script setup lang='ts'>
const mapComp: any = {
Record
};
const formComponent = computed(() => {
return mapComp[route.params.type as keyof typeof mapComp];
});
</script>
Then the browser reports two warnings
After modification:
<template>
<component
ref="formComponent"
:is="mapComp[route.params.type as string]"
/>
</template>
<script setup lang='ts'>
import {useRoute} from 'vue-router'
const route = useRoute()
const mapComp: any = {
Record
};
const formComponent = ref<string>(route.params.type as string);
</script>
At this point, the problem is solved
java.lang.UnsatisfiedLinkError: dlopen failed: /lib/arm64/libc++_shared.so not found
1. Error description
When using other so libraries, sometimes you may encounter libc++_shared.so library cannot be found:
java.lang.UnsatisfiedLinkError: dlopen failed: "/data/app/com.niuba.demo-t5NvrZc62MoQOW2PzC1Rvw==/lib/arm64/libc++_shared.so" not found
2. Cause of error
The so library used depends on the libc++_shared.so library file
3. Solutions
Go to any ndk version directory in the ndk directory, there are various versions in the llvm-libc++\libs directory
For example:
ndk\23.1.7779620\sources\cxx-stl\llvm-libc++\libs
Pytoch reports an error:

An error is reported if the pre training model is not downloaded
resnet101 = torchvision.models.resnet101(pretrained=True)
Solution:
Delete the file C:\Users\Username/.cache\torch\hub\checkpoints.pth
open failed: ENOENT (No such file or directory)
1. Error description
The following error occurred while writing the file to sdcard:
open failed: ENOENT (No such file or directory)
2. Error analysis
At first, I thought I forgot to add read-write permission, which was checked.
Finally, when I think of android10 onwards, in addition to the dynamic application of permissions, you must add in the Application node of AndroidManifest.xml of the main application.
android:requestLegacyExternalStorage="true"3. Solution
Add the following codes in the Application node of AndroidManifest.xml of the main application:
android:requestLegacyExternalStorage="true"
# org.springframework.context.ApplicationContextException: Failed to start bean ‘documentationPluginsBootstrapper’; nested exception is java.lang.NullPointerException

</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
At this point, my spring-boot-starter version may not match the swagger version, and the following error is reported
org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException
Because Springfox uses path matching based on AntPathMatcher, while Spring Boot 2.6.X uses PathPatternMatcher.
Solution:
Configurate in application.properties:
spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHER
The problem can be solved.
Error Messages:
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Solution: Modify the configuration
