在 node_modules/jest-diff/build/diffLines.d.ts 中构建 React + Typescript 错误

Question

我目前正在开发一个使用 React 和 Typescript 的项目，该项目运行良好，直到最近使用 Jenkins 构建时发生以下错误（并且该错误也出现在我的计算机上的 intellij 中）。似乎是一个模块作为编译错误。

[INFO] Creating an optimized production build...
[INFO] Failed to compile.
[INFO] 
[INFO] /jenkins/workspace/project/front/node_modules/jest-diff/build/diffLines.d.ts
[INFO] TypeScript error in /jenkins/workspace/project/front/node_modules/jest-diff/build/diffLines.d.ts(8,13):
[INFO] '=' expected.  TS1005
[INFO] 
[INFO]      6 |  */
[INFO]      7 | import { Diff } from './cleanupSemantic';
[INFO]   >  8 | import type { DiffOptions } from './types';
[INFO]        |             ^
[INFO]      9 | export declare const diffLinesUnified: (aLines: string[], bLines: string[], options?: DiffOptions | undefined) => string;
[INFO]     10 | export declare const diffLinesUnified2: (aLinesDisplay: string[], bLinesDisplay: string[], aLinesCompare: string[], bLinesCompare: string[], options?: DiffOptions | undefined) => string;
[INFO]     11 | export declare const diffLinesRaw: (aLines: string[], bLines: string[]) => Diff[];

我在这里有点迷茫，所以有人有解决这个问题的线索吗？提前致谢。

这是我的 package.json 文件

Typescript 3.8.0 支持纯类型导入和导出。

设置 Typescript version >= 3.8.0 以解决此错误。
