解决nextjs部署到now上之后出现的“Unable to import module ‘now__launcher‘”错误
这个错误是由于在next.config.js中直接引用了withLess之类的插件导致的。在now环境下require插件需要在PHASE_PRODUCTION_SERVER阶段下,如果不加这个阶段的判断就会报错。
这个是错误的做法
// ? Don‘t put this here
const withCSS = require(‘@zeit/next-css‘); // 由于不在PHASE_PRODUCTION_SERVER阶段所以报错 const { PHASE_PRODUCTION_SERVER } = process.env.NODE_ENV === ‘development‘ ? {} : !process.env.NOW_REGION ? require(‘next/constants‘) : require(‘next-server/constants‘); module.exports = (phase, { defaultConfig }) => { if (phase === PHASE_PRODUCTION_SERVER) { // Config used to run in production. return {}; } return withCSS(); };
正确的写法:
const { PHASE_PRODUCTION_SERVER } = process.env.NODE_ENV === ‘development‘ ? {} : !process.env.NOW_REGION ? require(‘next/constants‘) : require(‘next-server/constants‘); module.exports = (phase, { defaultConfig }) => { if (phase === PHASE_PRODUCTION_SERVER) { // Config used to run in production. return {}; } // ? Put the require call here. const withCSS = require(‘@zeit/next-css‘); return withCSS(); };
