Unable to build website for locale `en`; TypeError: pathname.match is not a function

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I’m using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

A TypeError appears on build. start works fine.

A google search comes up with some information on the inputs of this api changing in a recent react-router release (~3 months ago) so perhaps something out of sync.

Reproducible demo

N/A

Steps to reproduce

docusaurus build

Config is fairly vanilla as follows. Note same behaviour without typedoc plugin.

// @ts-check
// Note: type annotations allow type checking and IDEs autocompletion

Your environment

• Public source code: N/A
• Public site URL: N/A
• Docusaurus version used:2.0.0-beta.21
• Environment name and version (e.g. Chrome 89, Node.js 16.4): Node v16.15.0
• Operating system and version (e.g. Ubuntu 20.04.2 LTS):Ubuntu 18 WSL

Self-service

• I’d be willing to fix this bug myself.

Have resolved this now, thank you for the pointer. The issue was an invalid package-lock.json (oh, npm) which incorrectly hoisted v6 of react-router rather than v5 and put v6 local to storybook.

I had essentially copied my entire repo to a new environment and been unable to reproduce when I decided to compare package-lock.json between my actual repo and the repro repo. Problem became obvious then and I nuked the incorrect package-lock.json and re-generated.

Maybe try a fresh installation locally? I actually prefer a GH repository to a CodeSandbox, if that works for you.
