尝试使用@babel/plugin-proposal-class-properties
。
产生此错误
Failed to compile.

Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation.
安装和代码如下。
sh
yarn add @babel/plugin-proposal-class-properties --dev
MyComponent.js
...
<Animatable.View
animation="pulse"
easing="ease-out"
iterationCount="infinite">
<SocialButton
onPress={signInWithGoogle}
imageSource={IMAGES.GOOGLE}
style={{
container: themedStyles.googleIconContainer,
image: themedStyles.googleIcon,
}}
/>
</Animatable.View>
...
babel.config.js
module.exports = {
presets: [ "module:metro-react-native-babel-preset", "@babel/preset-env", "@babel/preset-react" ],
plugins: [ ["@babel/plugin-proposal-class-properties", {"loose": true}] ],
}
这些SO注释似乎没有帮助。

您必须安装
npm install @babel/core @babel/plugin-proposal-class-properties @babel/preset-env @babel/preset-react babel-loader
和
<块引用>更改输入和输出
const path = require('path')
module.exports = {
entry: path.resolve(__dirname,'src', 'app.js'),
output: {
path: path.resolve(__dirname, "public","dist",'javascript'),
filename: 'bundle.js'
},
module: {
rules: [
{
test: /\.(jsx|js)$/,
exclude: /node_modules/,
use: [{
loader: 'babel-loader',
options: {
presets: [
['@babel/preset-env', {
"targets": "defaults"
}],
'@babel/preset-react'
],
plugins: [
"@babel/plugin-proposal-class-properties"
]
}
}]
}
]
}
}
在文件webpack.config.js
