Error report of GoLand project after go reloading Error:cannot find The solution of package error

Upgrade the version of golang, uninstall the old version of go, download and install the new version of go. After installation, open the GoLand compilation project and report an error, Tips error:cannot find Package XXXX. If you look at the project carefully, there is no change. The original reason is that the installation program of golang will automatically generate an environment variable gopath, which is different from my original configuration. You can solve the problem by modifying the environment variable gopath.

4. Solve the problem of error: command error out with exit status 1

5. After installing scikit learn, it can be imported, but the running error is: importerror: DLL load failed: the specified program cannot be found

 

—————————————————————————————————————————————————————-

 

This error is due to the dependency package version is too high (too new).

Phenomenon restore: install scikit learn with anaconda, and then install Matplotlib to report the above error.

Solution: the installed version of Matplotlib is too high, and it can be solved by reducing the version.

 

 

However, this is not the end. Generally, scikit learn installed with the CONDA command may import normally, but it is easy to report an error when using it

The solution is to uninstall sklearn, and then use pip to install it again. However, if you directly use the PIP install scikit learn command to install it, there may be errors, and the process of installing again will be very complicated

See:

After installing sklearn, it can be imported normally, but an error is reported

When integrating redis with SSM framework, error creating bean with name ‘rediscontentserviceimpl’ defined in file

When integrating redis in SSM framework, error creating bean with name ‘rediscontentserviceimpl’ defined in file

Error report: there is a problem with bean dependency, that is, there is a problem with bean injection. Finally, we found that there was a problem with the version of the connection between redis and jedis. We found a new version and solved it.

        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.7.3</version>
        </dependency>
        <!-- spring-redis-->

Error creating bean with name ‘redistemplate’ defined in class path resource

I set up a set of projects, using springboot version 2.3.0. When I started, I repeatedly reported errors, so I started a long journey of error finding. At first, I thought it was because the framework was not well configured. Finally, I found that it was the problem of redis.

Error one

org.springframework.data . redis.connection.RedisConnectionFactory ’ that could not be found

Error two

Error creating bean with name ‘redisTemplate’ defined in class path resource

reason

I report an error because I didn’t introduce the jedis dependency. Another reason is that the Maven dependent versions of jedis and spring boot starter data redis are incompatible, which is a common problem. The same is true when the jedisconnectionfactory cannot be created.

solve

Just introduce the jedis dependency to solve the problem

   <!--redis cache-->
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-data-redis</artifactId>
   </dependency>
   <!--spring boot2.x The above version needs to be introduced, otherwise the startup will report an error!-->
   <dependency>
       <groupId>redis.clients</groupId>
       <artifactId>jedis</artifactId>
   </dependency>

Launch again

K8S error validating data: ValidationError(Deployment.spec): missing required field selector

The following error is reported

This is an error when I execute the pod copy of the deployment controller. The meaning of the error is:
deployment verification error. The selector parameter must be specified in the deployment spec module.

Original yaml file

In Deployment.spec In the module, only the number of replicas is specified, and the replica label needs to be specified to match the deployment controller

apiVersion: apps/v1     #Api interface version
kind: Deployment #define controller
metadata:      
 name: nginx-deployment #deployment name
spec:       
 replicas: 3 #Under the specific parameter information spec, only the number of replicas is specified, you also need to specify the replica tag to match the Deployment controller

 template:
   metadata: 
     labels: 
       app: nginx-deployment   
   spec:
     containers:    	
       - name: nginx-deployment  	
         image: nginx:1.7.9  
         ports:   	 
           - containerPort: 80

Solution: modify yaml file

As shown in the figure above, write the selector tag parameters of the full spec according to the tags on the picture, matching with pod and deployment

Execute yaml script

kubectl apply -f deployment.yaml --record

Vue Error in callback for immediate watcher “height”: “TypeError: Cannot read property ‘style’ of

Vue error vue.esm.js?eaf6 :628 [Vue warn]: Error in callback for immediate watcher “height”: “TypeError: Cannot read property ‘style’ of undefined”

TypeError: Cannot read property ‘style’ of undefined

As follows:

The error is because tabledata is an empty array this.monthTradingTableHeight This is empty

solve:

1. Do not render when there is no data, and add a style with no data

code:

effect:

2. Or HTML code unchanged, modify JS, and give it when there is no data this.monthTradingTableHeight If you assign a value or ‘auto’, you will not report an error

code:

this.monthTradingTableHeight = tableData.length > 9 ? '310' : 'auto'

effect:

Here I choose the first solution, which is to add a style with no data.

On the error report after the command of ADB shell error:device not A solution of found

When debugging Android development and connecting mobile phones, it is clear that the development mode has been turned on and USB debugging is allowed. After connecting the mobile phone, the device still cannot be found, and an error is reported after inputting the ADB shell in the console error:device not found。 The methods on the Internet can be roughly divided into:
1. ADB kill server to kill the ADB process, and then use the ADB start server command to start it;
2. Detect port 5037（ adb.exe Whether the default port is occupied or not adb.exe For processes that occupy port 5037, restart the ADB service:
2.1. ADB nodeamon server: check whether port 5037 is occupied;
2.1 2.2, netstat – ano | findstr “5037”: check which process occupies port 5037;
2.3, tasklist | findstr “21152”: check which program created this process (21152 is the PID of a process occupying port 5037);
2.4, taskkill/F/PID 21152: turn off the process;
2.5, ADB devices: display the current connected devices.
Another solution is provided here, by manually viewing the hardware ID and installing Google native Android debug driver;
1. Right click my computer – & gt; management – & gt; device management – & gt; Android phone. Here we can see the corresponding Android device driver.
2. Right click the attribute of the driver, select the hardware ID in the attribute (P) option under the details option, and record the information in the following value (V). For example, the value of a device is:

USB\VID_2A45&PID_0C02&REV_????&MI_01
USB\VID_2A45&PID_0C02&MI_01

Focus on 2a45 and 0c02.
3. Find the SDK directory of Android development and download (assuming you have downloaded it through the SDK manager) in the computer, and enter into the system of ⁃ extras ⁃ Google ⁃ USB_ In the driver folder, find Android_ winusb.inf This is a Google configuration file for Android. Found in file[ Google.NTx86 ](for 32-bit platform, 64 bit is the same as adding) in this line, you can see a lot of Android device driver information below, for example:

;Google Nexus One
%SingleAdbInterface%        = USB_Install, USB\VID_18D1&PID_0D02
%CompositeAdbInterface%     = USB_Install, USB\VID_18D1&PID_0D02&MI_01

Here, we only need to copy the driver information in the format of this file, and modify it with 2a45 and 0c02 obtained in 2, as follows:

;MEIZU metal
%SingleAdbInterface%        = USB_Install, USB\VID_2A45&PID_0C02
%CompositeAdbInterface%     = USB_Install, USB\VID_2A45&PID_0C02&MI_01

Save and close.
4. Uninstall the original driver and restart the computer. Make sure that the mobile phone has entered the developer mode and allows USB debugging. Select the connection mode to transfer files. Then right click computer – & gt; manage – & gt; device management – & gt; other devices again. You can see a question mark on the ADB interface option, indicating that the driver is not installed correctly. Select the ADB interface and right-click to select Update Driver Software – & gt; browse the computer to find the driver software. In browsing, select Android, the hardware device driver information file that we added before_ winusb.inf The folder of (d): – Android – SDK – Extras – Google – USB_ In this case, you only need to select a folder, not a file). Next, choose always install.
5. After successful installation, an Android phone option will appear in device management.
