npm install problem related to version conficts

[yangjun1222]

After I git clone and cd OATutor, run the command "npm install", version conflict:
npm WARN EBADENGINE Unsupported engine { npm WARN EBADENGINE package: '@cortex-js/compute-engine@0.22.0', npm WARN EBADENGINE required: { node: '>=16.14.2', npm: '>=8.5.0' }, npm WARN EBADENGINE current: { node: 'v12.22.9', npm: '8.5.1' } npm WARN EBADENGINE } npm WARN EBADENGINE Unsupported engine { npm WARN EBADENGINE package: '@csstools/postcss-trigonometric-functions@1.0.2', npm WARN EBADENGINE required: { node: '^14 || >=16' }, npm WARN EBADENGINE current: { node: 'v12.22.9', npm: '8.5.1' } npm WARN EBADENGINE } ..................................................
after I upgrade the node, npm install again, which says:
` npm install
npm warn EBADENGINE Unsupported engine {
npm warn EBADENGINE package: 'http2@3.3.7',
npm warn EBADENGINE required: { node: '>=0.12.0 <9.0.0' },
npm warn EBADENGINE current: { node: 'v18.20.6', npm: '10.8.2' }
npm warn EBADENGINE }

`
Do you know if I installed it successfully?
