NPM 警告：“不支持的引擎”

Question

I entered the command npm install -D tailwind css postcss autoprefixer vite in VS-Code.

My environment is:

• NPM version: 8.1.2
• Node.js version: 16.13.1

Which resulted in following warning:

npm WARN idealTree Removing dependencies.vite in favor of devDependencies.vite
npm WARN EBADENGINE Unsupported engine {    
npm WARN EBADENGINE   package: 'amqplib@0.5.2',    
npm WARN EBADENGINE   required: { node: '>=0.8 <=9' },
npm WARN EBADENGINE   current: { node: 'v16.13.1', npm: '8.1.2' }

Answer 1

It also happened to me while I was trying to install tailwindcss and I installed tailwind by mistake. Just uninstall it if that's also your case.

Answer 2

Its not a breaking error, just means that some functionalities might not work as expected. As this npm WARN EBADENGINE required: { node: '>=0.8 <=9' } line shows, the required node version for this package to work as intended is between 0.8 and 9 but you have node 16.

Answer 3

I faced with the same warning when I was try to install tailwind in my project:

npm WARN EBADENGINE Unsupported engine {
npm WARN EBADENGINE   package: '@eslint/eslintrc@1.3.0',
npm WARN EBADENGINE   required: { node: '^12.22.0 || ^14.17.0 || >=16.0.0' },
npm WARN EBADENGINE   current: { node: 'v14.16.1', npm: '8.2.0' }
npm WARN EBADENGINE }

So, I upgraded node.js version to 14.17.0 , and warning gone. You can find release you need by this link - https://nodejs.org/en/download/releases/

Answer 4

Need to change the node version. you can use node version manager for that https://github.com/nvm-sh/nvm[enter link description here][1]
