问题描述
我对乏味的/ webpack /节点/电子有疑问吗?我不确定。
复制步骤:
-
git clone https://github.com/codesbiome/electron-react-webpack-typescript-2020
-
yarn install
-
yarn add tedious
-
yarn add @types/tedious
然后将以下行添加到App.tsx
(或其他任何地方,仅此而已):
const connectToDb = (): Promise<Connection> => {
return new Promise((resolve,reject) => {
const config = { // those data doesn't matter much
authentication: {
options: {
userName: "sa",// update me
password: "" // update me
},type: "default"
},server: "test_db@localhost",// update me
options: {
database: "test",//update me
encrypt: true
}
};
const connection = new Connection(config) // error is caused by this
connection.connect()
})
}
connectToDb().then(res => {
console.log('res: ',res);
}).catch(err => {
console.log('err: ',err);
})
并且控制台(View -> Toggle Developer Tools
)中发生以下错误
Uncaught ReferenceError: require is not defined
at Object.events (index.js:140037)
at __webpack_require__ (index.js:790)
at fn (index.js:101)
at Object../node_modules/tedious/lib/bulk-load.js (index.js:99091)

at Module.<anonymous> (index.js:139704)
单击堆栈跟踪中的第一个重定向,显示此module.exports = require("events")
中的错误,这正是问题所在的require
。
我尝试操纵webpack
设置也尝试启用nodeIntegration
和其他设置,但没有任何结果。有什么想法吗?
解决方法
我知道了。
修复:
main.tsx
-> BrowserWindow
-> webPreferences
,将contextIsolation
更改为false
,也将nodeIntegration
更改为true
。
更改后,要求参考错误消失。
