Original download command:

npm i --save axios

Solution: Add: --legacy-peer-deps to the original download command

npm i --save axios --legacy-peer-deps

 That will solve the problem. You can check whether there is an "axios version number" in the package.json file. If so, the download will be successful.

To use axios: import first

import axios from 'axios'//要先导入

axios.get('url').then(res=>{console.log(res)})//再使用

Note: Any foreign modules used in the components under the src folder must be imported. Axios must also be imported after downloading it. Don’t forget it! ! ! ! 

learn by analogy:

Why the above error occurs:

• This is because the npm version is too high. The requirements will be stricter after it is higher than 7;
• npm -V can check the version of npm

The --legacy-peer-deps flag was introduced in v7 to bypass peerDependency automatic installation; it tells NPM to ignore issues with identical modules but different versions between various modules introduced in the project and continue with the installation.

So if the above error occurs when downloading other things in the future, just add: --legacy-peer-deps after the command  ;

For example, download swiper:

If  npm i --save swiper doesn't work, add --legacy-peer-deps and download again;

npm i --save swiper --legacy-peer-deps
