reactjs – 如何修复流错误“TouchHistoryMath.重复的模块提供者“

2019年7月28日 180次阅读

我正在配置一个新项目,并在遇到以下流错误时开始导入一些库.这个错误意味着什么,我该如何诊断和修复？这是一个反应本机项目,我最近添加了subscriptions-transport-ws库.

Launching Flow server
Spawned flow server (pid=13272)
node_modules/react-native/Libraries/Renderer/src/renderers/shared/stack/event/eventPlugins/TouchHistoryMath.js:0
TouchHistoryMath. Duplicate module provider
current provider. See: node_modules/react-native-gesture-responder/library/TouchHistoryMath.js:0

的package.json

"scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "flow": "node_modules/.bin/flow",
    "flow-stop": "node_modules/.bin/flow stop"
},
"dependencies": {
    "@shoutem/ui": "^0.10.9",
    "apollo-client": "0.8.0",
    "graphql": "^0.9.1",
    "graphql-tag": "^1.2.4",
    "lodash": "^4.17.4",
    "react": "~15.4.0",
    "react-apollo": "^0.10.1",
    "react-native": "0.41.2",
    "react-native-lock": "^0.4.0",
    "react-redux": "^5.0.2",
    "redux": "^3.6.0",
    "redux-actions": "^1.2.1",
    "redux-persist": "^4.4.0",
    "redux-thunk": "^2.2.0",
    "subscriptions-transport-ws": "^0.5.1"
},
"devDependencies": {
    "babel-eslint": "^7.1.1",
    "babel-jest": "18.0.0",
    "babel-preset-react-native": "1.9.1",
    "eslint": "^3.15.0",
    "eslint-config-airbnb": "^14.1.0",
    "eslint-plugin-import": "2.2.0",
    "eslint-plugin-jsx-a11y": "^4.0.0",
    "eslint-plugin-react": "6.9.0",
    "flow-bin": "0.37.0",
    "jest": "18.1.0",
    "react-test-renderer": "~15.4.0"
},
"jest": {
    "preset": "react-native"
}

最佳答案 我相信这是由两个具有相同名称的模块引起的错误.解决这个问题的解决方法是告诉Flow忽略其中一个模块.换句话说,在.flowconfig文件的[ignore]部分下添加以下一行(或两行)：

.*/node_modules/react-native/Libraries/Renderer/src/renderers/shared/shared/event/eventPlugins/TouchHistoryMath.js
.*/node_modules/react-native-gesture-responder/library/TouchHistoryMath.js

注意：这些文件中的第一个似乎是核心react-native库的一部分,而第二个文件来自@ shoutem / ui使用的依赖.我不确定从Flow中排除任何这些文件是否有任何副作用.
