4. Frequently Asked Questions

　　1. Vue installation npm install error

	#清楚npm缓存，然后重新安装npm install
	npm cache clean --force

　　2. Enter the wrong folder. It must be the project file you created.

　　3. Insufficient permissions. If the project is created in root mode, when using vscode to develop and modify, it will prompt that the permissions are insufficient. Every time you are asked to enter the root password, you can upgrade the user to an administrator and develop under the administrator's condition ( Set before environment installation), or modify the owner and group of the file.

Upgrade ordinary user to root user

		vim /etc/passwd
#找到自己的用户，将后面的数字改为0 与 0 就是与第一个用户root那个0 0一样

Change file owner

chown -R 用户  /tmp/testfile    #更改文件及其子文件的所属者属性

Modify the group to which a file belongs

chgrp  -R 组名  /tmp/testfile  #更改文件及其子文件的所属组属性

2. Vscode installation (app store installation)
