现在我正在使用带有webpack配置的vue-cli,这在Internet Explorer 10上遇到了麻烦。问题是webpack没有将let
或const
转换为{{ 1}}和IE 10不支持var
和let
等ES5变量。
以下是const
代码。
webpack.base.conf.js
编译后的代码会在IE10上用以下行引发错误module.exports = {
context: path.resolve(__dirname, '../'),
entry: {
app: ['babel-polyfill','./src/main.js'],
},
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath
: config.dev.assetsPublicPath
},
resolve: {
extensions: ['.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
}
},
module: {
rules: [
...(config.dev.useEslint ? [createLintingRule()] : []),
{
test: /\.vue$/,
loader: 'vue-loader',
options: vueLoaderConfig
},
{
test: /\.js$/,
loader: 'babel-loader',
include: [resolve('src'), resolve('test')]
},
{
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('img/[name].[hash:7].[ext]')
}
},
{
test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('media/[name].[hash:7].[ext]')
}
},
{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
}
}
]
},
node: {
// prevent webpack from injecting useless setImmediate polyfill because Vue
// source contains it (although only uses it if it's native).
setImmediate: false,
// prevent webpack from injecting mocks to Node native modules
// that does not make sense for the client
dgram: 'empty',
fs: 'empty',
net: 'empty',
tls: 'empty',
child_process: 'empty'
}
}
。
...让a = ...
但是,我所知道的是,webpack基本上将SCRIPT1002
和let
转换为const
,但结果却没有。我怎么强迫变换?
答案 0 :(得分:1)
问题是...... 不是vue
本身,而是node_modules
中的包。其中一个包基本上没有被编译(在我的例子中,buefy
库),所以我必须手动编译。
<强>解决方案强>
webpack.base.conf.js
将buefy添加到转换条目中(据我所知,vue-cli webpack会忽略node_modules中的包以解决性能问题)。
{
test: /\.js$/,
loader: 'babel-loader',
include: [/node_modules\/buefy/, resolve('src'), resolve('test')]
},
添加新别名以导入手动转换的包。
resolve: {
extensions: ['.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
'buefy$': resolve('node_modules/buefy/src'),
}
}
