@xmasuhai

It looks like you have the environment variable COREPACK_NPM_REGISTRY set to https://registry.npmmirror.com/. Is that correct?

If yes, have you tried setting it to https://registry.npmmirror.com instead (without the trailing / character).

[MikeMcC399]

It looks like there are 2 issues involved:

1. The Chinese npm mirror https://registry.npmmirror.com/ rejects the URL https://registry.npmmirror.com//pnpm whereas the official npm registry https://registry.npmjs.org accepts the URL https://registry.npmjs.org//pnpm and Corepack is then able to install:

Installing pnpm@10.10.0 from https://registry.npmjs.org//pnpm/-/pnpm-10.10.0.tgz

2. Corepack should not be building the URL with a double slash //. It should strip it down to https://registry.npmmirror.com/pnpm instead. See Requests with double slash using trailing slash (/) in COREPACK_NPM_REGISTRY #711

Relates also to #535, #540 and #458
