The process of installing node-sass and sass-loader and the node-sass version number corresponding to each node version

1. `node` Version, `node-sass` version and `sass-loader` version view:

node First, check my
version: Enter the query command on the command line : node -v
My node version is:v14.19.0

其二、我的 node-sass 版本查看："node-sass": "^4.14.1"

其三、我的 sass-loader 版本查看："sass-loader": "^7.3.1"

2、node 版本与 node-sass 版本的对应关系：其一、查看文档的地址：

https://www.npmjs.com/package/node-sass

其二、对应关系的表格：

`3、可能安装 node-sass 或 sass-loader 遇到的报错的提示：其一、安装 node-sass 过程中可能的报错信息为：一般要按照版本安装，不要直接npm i node-sass`

Second, `sass-loader` the possible error messages during the installation process are:
// At this time: the installed `sass-loader` version does not match;

Third, how to install the appropriate sass-loader version:
My current method is:
identify the corresponding node version number, determine one, and then switch back and forth between the sass-loader versions. The fault tolerance rate is very high;

Fourth, there is no wrong version correspondence between node, node-sass and sass-loader for me:

node: v14.19.0;
node-sass: ^4.14.1;
sass-loader: ^7.3.1;
