Webpack babel-loader runtime: Module build failed: TypeError: this.setDynamic is not a function
Webpack babel-loader runtime: Module build failed: TypeError: this.setDynamic is not a function
我正在尝试将 babel-loader
与 babel-plugin-transform-runtime
一起使用。
我已按照以下网址的说明进行操作:
https://github.com/babel/babel-loader#babel-is-injecting-helpers-into-each-file-and-bloating-my-code
相关代码:
rules: [
// the 'transform-runtime' plugin tells babel to require the runtime
// instead of inlining it.
{
test: /\.js$/,
exclude: /(node_modules|bower_components)/,
use: {
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env'],
plugins: ['@babel/transform-runtime']
}
}
}
]
构建时出现以下错误:
Module build failed: Error: Cannot find module '@babel/plugin-transform-runtime'
如果我将插件名称更改为:plugins: ['transform-runtime']
,我会收到以下错误:
Module build failed: TypeError: this.setDynamic is not a function
有什么问题?
您的 webpack 条目看起来与示例相同,所以我想知道如果您使用 .babelrc
.
会发生什么
{
"plugins": ["transform-runtime"]
}
您是否也安装了 env 预设?
经过一番努力,我找到了正确的方法。
Tl;dr
如果你安装了新的 babel 加载器,你应该加载新的 babel 插件。
全文
官方文档中的安装:
npm install babel-loader@8.0.0-beta.0 @babel/core @babel/preset-env webpack
在 github 页面中,这些是 runtime
插件的说明:
NOTE: You must run npm install babel-plugin-transform-runtime
--save-dev to include this in your project and babel-runtime itself as a dependency with npm install babel-runtime --save.
相反,您应该像这样使用新版本:
npm install --save-dev @babel/plugin-transform-runtime
npm install --save @babel/runtime
然后它将与文档中的配置一起工作。
首先,正如@yccteam 指出的那样,需要安装
npm install --save-dev @babel/plugin-transform-runtime
npm install --save @babel/runtime
.babelrc 文件应该有
{
"presets": [
["@babel/preset-env", {
"debug": false,
"modules": false,
"useBuiltIns": false
}],
"@babel/preset-react"
],
"plugins": [
"@babel/syntax-dynamic-import",
"@babel/plugin-transform-runtime",
[ "@babel/plugin-proposal-class-properties", { "loose": true } ],
"@babel/transform-async-to-generator"
],
"env": {
"production": {
"presets": ["react-optimize"]
}
}
}
webpack.js 文件应如下所示
module: {
rules: [
{
test: /(\.js[\S]{0,1})$/i,
exclude: /node_modules/,
loader: 'babel-loader',
query: {
presets: ['@babel/preset-react', '@babel/preset-env'],
plugins: ['@babel/proposal-class-properties']
},
},
...
