這是什麼？ http://meta.stackexchange.com/questions/80538/how-to-ask-questions-on-stack-overflow –

請提供'webpack.config.js'的代碼。閱讀[this]（http://stackoverflow.com/help/mcve） – wuxiandiejia

[Getting：Error：\ output.path \'必須是絕對路徑或\'/ \']（http：/ /stackoverflow.com/questions/42166492/getting-error-output-path-needs-to-be-an-absolute-path-or） –

該錯誤信息是明確的：output.path必須

你output.path應該寫這樣的絕對路徑或/：

var path = require('path'); 

output: { 
    path: path.join(__dirname, './dist/'), 

}
