升级到 monaco-editor 0.21.0 后，在玩笑测试中出现“标识符‘全局’已在compileFunction中声明”错误

Question

我升级了我的 React 项目以使用 monaco-editor 版本 0.21.0，从那时起，对导入 monaco-editor 的文件的玩笑测试开始失败，并出现以下错误：

\n

\xe2\x97\x8f Test suite failed to run\n\n/Users/omerharoon/Documents/code/packages/webapp/node_modules/monaco-editor/esm/vs/editor/editor.api.js:20\nconst global = self; // Set defaults for standalone editor\n      ^\n\nSyntaxError: Identifier 'global' has already been declared\n    at compileFunction (<anonymous>)\n\n  2 | \n  3 | import React from 'react';\n> 4 | import * as monaco from 'monaco-editor';\n    | ^\n  5 | import { Resizable } from 're-resizable';\n  6 | import {\n  7 |   getLanguageFromFilename,\n\n  at Runtime._execModule (node_modules/jest-runtime/build/index.js:1179:56)\n  at Object.<anonymous> (src/components/helpers/MonacoEditor/index.tsx:4:1)\n  at Object.<anonymous> (src/components/helpers/MonacoEditor/monaco_colorization.spec.tsx:6:1)\n

这种情况在升级后就开始发生，旧版本是 0.19.3，所有测试在该版本上都运行良好。monaco-editor-webpack-plugin 也从 1.9.0 升级到 2.0.0

我们直接从摩纳哥进口

以克服延迟加载问题。
