[Solved] tar (child): bzip2: Cannot exec: No such file or directory tar (child): Error is not recoverable: ex

What should I do if I get an error unpacking?
tar (child): bzip2: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

The problem is that the corresponding decompression software bzip2 is not installed
yum install bzip2

Decompress again, success!!!

RuntimeError: implement_array_function method already has a docstring(Pycharm install package error)

Recently, I’m writing the course of financial analysis and prediction in Python. Because I’m lazy, I didn’t match the required Library under CONDA in advance. Using pychar install package directly will lead to some version incompatibility and mismatching due to the installation sequence, which leads to
runtimeerror: implementation_ array_ Function method already has a docstring

[Solved] IDEA Import springboot Project Error: Cannot resolve plugin org.springframework.boot:spring-boot-maven-plugin:＜unknown＞

Today, after pulling the springboot project from gitee, I found that idea directly reported an error. The error is as follows:

Cannot resolve plugin org.springframework. boot:spring-boot-maven-plugin :

At first, I thought it was an error in the project. Later, baidu found that the default Maven configuration file and the default local warehouse address were used in the configuration of the project.

resolvent:

Open file — & gt; Settings –> Build, Execution, Deploymen –> Build Tools –>   Maven, find the user Maven configuration file and local warehouse address, and modify it to the local configuration file path and warehouse address.

Before revision:

After modification:

Refresh Maven again and solve the problem

How to React page to achieve entry and exit animation

React animated router dependency

file: https://www.npmjs.com/package/react-animated-router
Replace the direct routing component switch with the animated router

The red mark is wrong

In the process of development (TS), we always report an error after replacement, saying that there is no necessary attribute. After looking at the source code and adding the following attributes, we report no error (enter, exit, appearance)
< AnimatedRouter enter exit appear> ... </ AnimatedRouter>

Simply record how to improve the appearance animation style

Introduce a style (‘react-animated-router/animal. CSS’) which is copied from the installation package. If you want to modify it, it is left and right animation by default

// ------Page in/out animation start-------
.animated-router-container {
  height: 100%;
}
.animated-router-in-transition {
  /* page animation in progress */
  position: relative;
  width: 100%;
  overflow: hidden;
}
.animated-router-forward-enter {
  transform: translate(-20px);
  opacity: 0;
}
.animated-router-forward-enter-active {
  transform: translate(0);
  opacity: 1;
}
.animated-router-forward-exit {
  transform: translate(0);
  opacity: 1;
}
.animated-router-forward-exit-active {
  transform: translate(100%);
  opacity: 0;
}
.animated-router-backward-enter {
  transform: translate(-20px);
  opacity: 0;
}
.animated-router-backward-enter-active {
  transform: translate(0);
  opacity: 1;
}
.animated-router-backward-exit {
  transform: translate(0);
  opacity: 1;
}
.animated-router-backward-exit-active {
  transform: translate(100%);
  opacity: 0;
}
.animated-router-forward-enter-active,
.animated-router-forward-exit-active,
.animated-router-backward-enter-active,
.animated-router-backward-exit-active {
  /* Transition time and jogging effect required for different transition phases */
  transition: all 0.4s ease-in;
}
.animated-router-forward-exit,
.animated-router-backward-exit {
  position: absolute !important;
  width: 100%;
  top: 0;
  left: 0;
}
// ------Page in/out animation end-------

When a warning appears, try to install the following two plug-ins

npm install [email protected] --save
npm install –save-dev prop-types

Another component library comes out of animation – ant motion

[How to Solve] Invalid bound statement (not found)

When integrating mybatis with springboot, an error of invalid bound statement (not found) is reported. After repeated changes and trial and error, it is found that mapper.xml cannot be scanned. The key lies in two aspects.

    1. if you put XML in the Java directory, you need to configure the path in the POM package
<resources>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/sqlmap/*.xml</include>
				</includes>
				<filtering>false</filtering>
			</resource>
			<resource>
				<directory>src/main/resources</directory>
				<includes>
					<include>**/*.*</include>
				</includes>
				<filtering>true</filtering>
			</resource>
		</resources>
      1. add the statement of scan mapping file to mybatis configuration class
 PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        sessionFactory.setMapperLocations(resolver.getResources("classpath*:**/sqlmap/*.xml"));//扫描映射文件
        1. if the mapper.xml file is placed in the resources directory, maperlocations should be configured in application.yml
mybatis:
  mapper-locations: classpath:mapping/*.xml  #Note: Be sure to correspond to the path where the mapper mapping xml file is located

Problem description

after rebooting ubuntu20.04, the resolution of the interface is not correct, and the following error appears when viewing the information of the graphics card: </ font>

> nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver

before the restart, there was no operation on the graphics card driver, just a system update using sudo apt get upgrade</ font>

Problem analysis and solution

1 Analysis

first of all, make sure that the driver of the graphics card has not moved, and the graphics card and other related hardware has not been replaced. Then, before the restart, the operation for the system is just to update the relevant software in the system by using sudo apt get upgrade. Therefore, it is speculated that the system kernel was updated during the update, and the new system kernel may not match the current graphics driver. Use the following command to view the kernel of the current system and all versions of the kernel that exist in the current system: </ font>

found that in addition to the current version of the kernel, there is another (relatively old) version of the kernel: 5.4.0-74-generic
therefore, in order to verify whether it is related to kernel update, restart the system, select Ubuntu advance option in grub startup interface, and start with a lower version kernel. Results after the restart, the resolution of the interface returned to normal, NVIDIA SMI could also find the related information of the graphics card driver</ font>

2 solution

to determine the problem, there are two main solutions: </ font>

Delete and uninstall the old version of the graphics card driver, and re install the graphics card driver on the basis of the new kernel. Continue to use the kernel version 5.4.0-74-generic when installing the graphics card driver, and uninstall the newly updated kernel version 5.4.0-77-generic. Then disable the kernel update and keep the current kernel

> # sudo vim /etc/default/grub
# View the currently installed kernel
> dpkg --get-selections| grep linux-image
linux-image-5.4.0-74-generic install
linux-image-5.4.0-77-generic install

The problem of inconsistent host names in building rabbitmq on Linux

1. Environment:

centos 7.3

2. Problem description

Today, the following error occurred in the process of deploying rabbitmq as a front-end and back-end message push

$ rabbitmqctl set_permissions -p/duni ".*" ".*" ".*"

Error: unable to connect to node rabbit@bbbbdddd: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@bbbbdddd]

rabbit@bbbbdddd:
  * connected to epmd (port 4369) on bbbbdddd
  * epmd reports node 'rabbit' running on port 25672
  * TCP connection succeeded but Erlang distribution failed

  * Hostname mismatch: node "rabbit@localhost" believes its host is different. Please ensure that hostnames resolve the same way locally and on "rabbit@localhost"


current node details:
- node name: 'rabbitmq-cli-92@bbbbdddd'
- home dir: /var/lib/rabbitmq
- cookie hash: h6TDjQ+DgPaVGJLMjcG4TA==

I can’t connect to the host where I deployed rabbitmq bbbbdddd

3. Google

Google found the corresponding problem in stack overflow

Here we say to give rabbitmq command permission, delete the service and then re install it. After trying, I found that I can’t do it…

Continue with Google, and some people say to correct Erlang’s Cookie:

Erlang will generate two cookie files: C: windows. Erlang. Cookie and C: user. Erlang. Cookie. Check whether the contents of the two files are consistent. If not, replace one with the other.

Windows platform, er… My environment is Linux, and I didn’t find two . Erlang. Cookie files in the root directory

$ find/--name .erlang.cookie
/var/lib/rabbitmq/.erlang.cookie

So I gave up.

4. Solutions

The final solution is to set the host name and restart the rabbitmq service

# Kill the rabbitmq process first
$ ps -ef | grep rabbitmq | grep -v grep | awk '{print $2}' | xargs kill -9

# set hostname (assume host ip is: 192.168.1.1, hostname set to: mq)
$ echo 192.168.1.1 mq > /etc/hosts
$ echo rabbitmq > /etc/hostname
$ export HOSTNAME=mq

# Restart rabbitmq
$ rabbitmq-server -detached
# Start the web socket service
$ rabbitmq-plugins enable rabbitmq_management rabbitmq_web_stomp
# Set up users and give them administrator privileges
$ rabbitmqctl add_user duni duni
$ rabbitmqctl set_user_tags duni administrator
# set user directory
$ rabbitmqctl set_permissions -p/duni ".*" ".*" ".*"
