图片的引用:

<img src="../assets/image/setting.png"/>

目录结构:

写的相对路劲,为什么图片没有显示出来?

                use: "file-loader"
            }
        ]
    },
    plugins: [
        new webpack.NamedModulesPlugin(),
        new webpack.HotModuleReplacementPlugin(),
        new HtmlWebpackPlugin({hash: false, template: "./index.hbs"}),
        new webpack.ContextReplacementPlugin(/moment[\/\]locale$/, /nb/)
    ]
};

原因找到了:

        contentBase: path.resolve(__dirname, "dist"),

路劲应该写相对于dist的路径
但是现在又有一个问题!这样写在生产环境肯定是显示不了图片的!
我不打算将静态资源放在/dist下,楼下说了static文件的方法,这个应该要配置webpack,有没有朋友分享一下

静态资源的问题已解决,解决方案:
使用webpack的一个插件,生产环境编译时可以将/static目录的文件拷贝到/dist目录下

new CopyWebpackPlugin([
    {
        from: path.resolve(__dirname, 'static'),
        to: path.resolve(__dirname, 'dist/static'),
        ignore: ['*.js']
    }
])

开发的时候的时候webpack-devserver配置:

contentBase: path.resolve(__dirname),
publicPath: "/",

这样在代码里面只要写绝对路径/static/..就行了

仅有的幸福

你写img的文件在哪里啊? "../assets/image/setting.png"这个只有你写img的文件在components目录下才有效.

我想大声告诉你

如果是使用vue-cli的webpack模板,会被转成绝对路径,如:/images/setting.png,建议将图片放在static文件夹下。

扔个三星炸死你

固定路径都放在/static下面把,唯一打包前打包后位置不变的地方
