我已将使用Babel 7的RN应用程序从0.55.4升级到0.56。
在0.55.4中为MOBX使用装饰器时,我使用“ babel-plugin-transform-decorators-legacy”,但与Babel 7不兼容...
本机版本:0.56.0 mobx版本:5.0.3 mobx反应版本:5.2.3
有人解决吗?
谢谢
更新:
该应用程序在DEBUG
中可以使用此配置
package.json
...
"devDependencies": {
"@babel/core": "7.0.0-beta.47",
"@babel/plugin-proposal-decorators": "7.0.0-beta.47"
...
}
.babelrc
{
"presets": [
["react-native"]
],
"plugins": [
["@babel/plugin-proposal-decorators", { "legacy": true }]
]
}
但是在RELEASE
xCode中,由于以下错误而崩溃:
babelHelpers.applyDecoratedDescriptor is not a function.
更新2,工作配置:
这是我的工作配置:
package.json
...
"devDependencies": {
"@babel/core": "7.0.0-beta.47",
"@babel/plugin-proposal-decorators": "7.0.0-beta.47",
"@babel/runtime": "7.0.0-beta.47",
"babel-jest": "23.2.0",
"babel-preset-react-native": "5.0.2",
"jest": "23.3.0",
"react-test-renderer": "16.4.1"
}
...
.babelrc
{
"presets": [
["react-native"]
],
"plugins": [
["@babel/plugin-proposal-decorators", { "legacy": true }]
]
}
然后在index.js(主应用程序起始文件)中,我需要导入装饰器babel库:
index.js
import applyDecoratedDescriptor from '@babel/runtime/helpers/es6/applyDecoratedDescriptor';
import initializerDefineProperty from '@babel/runtime/helpers/es6/initializerDefineProperty';
Object.assign(babelHelpers, {applyDecoratedDescriptor, initializerDefineProperty});
require('./app.js');
app.js
import {AppRegistry} from 'react-native';
import AppName from './app/index';
AppRegistry.registerComponent(appName, () => AppName);

好吧,我通过添加@babel/runtime
解决了所有错误,现在该应用程序也可以在DEBUG
和RELEASE
中工作。
这里是正确的配置:
package.json
...
"devDependencies": {
"@babel/core": "7.0.0-beta.47",
"@babel/plugin-proposal-decorators": "7.0.0-beta.47",
"@babel/plugin-transform-runtime": "7.0.0-beta.47",
"@babel/runtime": "7.0.0-beta.47",
"babel-jest": "23.2.0",
"babel-preset-react-native": "5.0.2",
"jest": "23.3.0",
"react-test-renderer": "16.4.1"
}
...
.babelrc
{
"presets": [
"react-native"
],
"plugins": [
["@babel/plugin-proposal-decorators", { "legacy": true }],
["@babel/plugin-transform-runtime", {
"helpers": true,
"polyfill": false,
"regenerator": false
}]
]
}
感谢@Hkan。

我通过安装@babel/plugin-proposal-decorators@7.0.0-beta.47
和@babel/plugin-transform-runtime@7.0.0-beta.47
解决了这个问题。
版本可能会因您而异。我使用这些版本是因为@babel/core
也位于7.0.0-beta.47
。
当前.babelrc
是:
{
"presets": [
"react-native"
],
"plugins": [
["@babel/plugin-proposal-decorators", { "legacy": true }],
["@babel/plugin-transform-runtime", {
"helpers": true,
"polyfill": false,
"regenerator": false
}]
]
}
