[英]How do I fix 'Cannot assign to read only property 'exports' of object '#<Object>' when adding a 2nd function to module.exports?
不幸的是，我已經被困了大約 5 天了。 我用谷歌搜索過，沒有什么對我有用。 我有一個 utils.js 文件，里面有很多東西可以幫助我。 當我將 function "doesUserContainRoles" 添加到導出時，我的 Chrome 控制台給了我錯誤：
Uncaught TypeError: Cannot assign to read only property 'exports' of object '#<Object>'
當我刪除 function 時，utils 文件中的所有內容都可以完美運行，根本沒有 0 個問題。 只要我添加 function，我就會收到此錯誤。 我通過以下方式要求 utils 文件：
const utils = require("../../../utils");
並且沒有與此一起使用的import 。 （我知道module.exports和import不能一起工作）
我正在使用什么：
Vue.js @vue/cli 4.5.8
Node.js v15.2.0
utils.js
const winston = require("winston");
const { datadog } = require("./credentials.js");
const { createLogger, format, transports } = require('winston');
const base_url = "http://localhost:3001/api/v1"
// Winston ~
const httpTransportOptions = {
host: datadog.logger.host,
path: datadog.logger.path,
ssl: datadog.logger.ssl
};
const customLevels = {
levels: {
emergency: 0,
alert: 1,
critical: 2,
error: 3,
warn: 4,
notice: 5,
info: 6,
debug: 7,
success: 8
},
}
const logger = createLogger({
level: 'info',
levels: customLevels.levels,
exitOnError: false,
format: format.json(),
transports: [
new transports.Http(httpTransportOptions),
],
});
const commonMessages = {
accessPage: "User Accessed a Page",
restrictedPage: "Attempt at accessing restricted page"
}
function alertGeneral() {
alert("Oops! An error has occurred. Please try again later. If this problem continues, please contact Vinniehat.");
}
function doesUserContainRoles(userRoles, containsRoles) {
return !!userRoles.some(role => containsRoles.includes(role));
}
module.exports = {
logger,
commonMessages,
base_url,
alertGeneral,
doesUserContainRoles
}
這是錯誤堆棧：

我也嘗試使用export default 。 這樣做時，我的前端工作。 網站加載沒有錯誤。 不過，我的后端使用 Express.js 運行，然后引發錯誤：

在main.js > router.js > utils.js的某個地方，您正在混合 CommonJSModules 和 ESModules。 CommonJSModule --requires--> ESModule --requires--> AnotherCommonJSModule的東西
