Create Vue cli project and report error command failed: Yarn

Create Vue cli project and report error command failed: Yarn

Solution 1:

Enter C:/users/administrator/in the windows environment

There is a file . Vuerc

Open this file to display

{
“useTaobaoRegistry”: true,
“packageManager”: “yarn”
}

Just manually change the configuration content yarn to NPM to change the package manager when the project is created

Solution 2:

Delete the. Vuerc file. When you create a Vue project for the first time, you will be prompted to select the configuration, and then select NPM.

Enter command

npm install -g yarn

After success, the problem can be solved by re creating vue-cli4 project.

Idea SpringBoot：Error creating bean with name ‘XXXXController‘

Problem Description:

Red when starter starts springboot:

  Error creating bean with name ‘indexController’

Error creating bean named ‘indexcontroller’

Error in bean of ‘sqlsessionfactory’: failed to instantiate bean through factory method

Problem solving:

According to the error report, it can be seen that the mapper layer is not injected and the mapper instance cannot be found. First, check the springboot core configuration file application.yml. In the mybatis configuration structure, the bean is not configured in the custom scan package type aliases package. Just reconfigure it (the package name depends on the individual)

Error 580 error LNK1104: unable to open file ‘DLL’

Question

Error 580 error LNK1104: unable to open the file “… \ bin \ polishpack. DLL” D: \ VS2010 \ Polish \ Polish \ polishpack \ link

analysis

This problem occurs when I compile the dynamic link library. The DLL file should be the output file, but it cannot be opened

reason

This file is contained in the.. \ bin folder and the link library is being called by its registrar. This file is being called and the operating system cannot create a file with the same name

terms of settlement

Close the operation of other projects, delete the output DLL file, and recompile the output
during the deletion process, the registration service may be called and cannot be deleted. The shutdown method is very easy to use. Ha ha ha, chicken is a stupid way.
