解决npm WARN EBADENGINE Unsupported engine { npm WARN EBADENGINE package: ‘pnpm@9.x.x’, npm WARN …

jenkins执行npm install -g pnpm@9.1.3会报
npm WARN EBADENGINE Unsupported engine { npm WARN EBADENGINE package: pnpm@9.1.3 , npm WARN EBADENGINE required: { node: >=18.12 }, npm WARN EBADENGINE current: { node: v16.17.0 , npm: 8.5.1 } npm WARN EBADENGINE }
缘由是从pnpm v9.0.0-rc.2开始不再对node 16版本进行支持

此时降低pnpm的版本即可解决
npm install -g pnpm@8.15.8
pnpm版本可以从Releases · pnpm/pnpm (github.com)查找
