TS1259: Module '"path"' can only be default-imported using the 'esModuleInterop' flag
时间: 2024-02-04 09:04:16 浏览: 35
这个错误是 TypeScript 编译器的一个提示,它告诉你需要在 tsconfig.json 中开启 esModuleInterop 选项才能正确地使用 import 语句导入 CommonJS 模块。esModuleInterop 选项允许你在导入 CommonJS 模块时使用 import 语法,而不是 require 语法。
你可以在 tsconfig.json 文件中添加 "esModuleInterop": true 选项来开启这个功能。如果你使用的是 VS Code 编辑器,编译器会自动检测这个选项并提示你开启它。
示例:
```
{
"compilerOptions": {
"esModuleInterop": true,
// 其他编译选项
}
}
```

Module '"d:/systemProject/system-vue/node_modules/@types/nprogress/index"' can only be default-imported using the 'allowSyntheticDefaultImports' flagts(1259) index.d.ts(45, 1): This module is declared with 'export =', and can only be used with a default import when using the 'allowSyntheticDefaultImports' flag.
这个错误是 TypeScript 编译器的一个警告,它告诉您,您需要在 TypeScript 配置文件中启用 `allowSyntheticDefaultImports` 标志。这个标志允许您使用默认导入来导入使用 `export =` 声明的模块。在您的 `tsconfig.json` 文件中添加以下行:
```
{
"compilerOptions": {
"allowSyntheticDefaultImports": true
}
}
```
这将解决这个问题。
Module not found: Error: Can't resolve 'element-ui' in
This error usually occurs when the module 'element-ui' is not installed or cannot be found in your project. To resolve this issue, you can try the following steps:
1. Make sure you have installed 'element-ui' in your project. You can do this by running the following command in your project directory:
```
npm install element-ui
```
or
```
yarn add element-ui
```
2. Check if the module is correctly imported in your code. Make sure you have the import statement for 'element-ui' at the beginning of your file:
```javascript
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
// ...
```
3. If you have installed 'element-ui' globally, make sure to import it in your main entry file (e.g., 'main.js' or 'app.js') as well.
If the issue persists, you may need to provide more details about your project setup and the specific error messages for further assistance.
