尝试导入错误：'path-to-regexp' 不包含默认导出（导入为 'pathToRegexp'）

Question

Failed to compile the react-router. This happend after installing path-to-regexp

./node_modules/react-router/esm/react-router.js

Attempted import error: 'path-to-regexp' does not contain a default export (imported as 'pathToRegexp').

This error occurred during the build time and cannot be dismissed.

Answer 1

For me, this occurred as my path-to-regex had been updated to newer version.

I solved this by simply reverting back to the old version of path-to-regex.To do that simply run this: npm i path-to-regexp@2.4.0 --save

Answer 2

Instead of downgrading to an old version, just change the way you import: from:

import pathToRegexp from 'path-to-regexp';

to

import { pathToRegexp } from 'path-to-regexp';
