我在我的应用程序中使用了一个TensorFlow编码器。当应用程序正在运行时,它在我的浏览器中正常工作,但是当我测试它是否成功构建时,出现了问题:
$ npx react-scripts test --env=jsdom
FAIL src/App.test.js
● Test suite failed to run
ReferenceError: TextEncoder is not defined

我想要摆脱那个错误。我尝试使用“text-encoding”包,但我不确定如何在导入发生之前正确定义TextEncoder。
也许我可以为--env
设置不同的选项?
在没有--env=jsdom
的情况下,我会收到相同的错误。我相信在遇到类似未定义错误时添加它后,它纠正了一个问题。
这是我的测试:
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
it('renders without crashing', () => {
const div = document.createElement('div');
ReactDOM.render(<App />, div);
ReactDOM.unmountComponentAtNode(div);
});
所以设置 --env=node
也不起作用,因为: ReferenceError: document is not defined
。
