Webpack URIError:无法解码参数'/%PUBLIC_URL%/favicon.ico'

时间:2018-10-11 08:10:32

标签: reactjs webpack webpack-dev-server webpack-4

webpack v4.20.2

webpack-dev-server v3.1.9

我正在使用webpackwebpack-dev-server运行React应用程序,遇到关于%PUBLIC_URL%的问题。

URIError: Failed to decode param '/%PUBLIC_URL%/favicon.ico'

%PUBLIC_URL%尚未在 index.html 中进行编译,因此未能获得收藏夹

public / index.html

<head>
  <meta charset="utf-8">
  <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
  <link rel="manifest" href="%PUBLIC_URL%/manifest.json">
</head>

package.json脚本

"scripts": {
    "dev": "webpack-dev-server --config ./config/webpack.dev.conf.js --open",
    "build": "webpack --config ./config/webpack.prod.conf.js"
  },

它与配置文件中的publicPath字段有关吗?

针对需要的人。 使用此插件interpolate-html-plugin(从react-scripts中提取)

第1步:

if ($('.customFormTable') .find('#elementTableContainerCheckHidden').css("visibility") === "hidden") { $('.customFormTable').hide(); //hide your parent table }

第2步:

在webpack配置的插件中,将此插件添加到其中。

npm install interpolate-html-plugin --save-dev

第3步:

运行项目,它可以正常工作
