Permission denied error when trying to install pnpm via Corepack as node user

Environment

• Node.js Version: 16.15.0
• Image Tag: lts-alpine

Expected Behavior

I should be able to install pnpm using Corepack as a non-privilegied user.

Current Behavior

When I try to install pnpm via Corepack (corepack enable) as non-privilegied user (-u node), I get the following error:

/app $ corepack enable
Internal Error: EACCES: permission denied, symlink '../lib/node_modules/corepack/dist/pnpm.js' -> '/usr/local/bin/pnpm'
Error: EACCES: permission denied, symlink '../lib/node_modules/corepack/dist/pnpm.js' -> '/usr/local/bin/pnpm'
/app $ 

Running corepack enable as root work as expected.

docker run -it -v $(pwd):/app node:lts-alpine /bin/sh

Steps to Reproduce

1. Create an empty project with the following package.json. The packageManager property is important here.

   {
       "name": "docker-node-pnpm",
       "version": "1.0.0",
       "private": true,
       "packageManager": "pnpm@7.1.7"
   }
   

2. Run the container as a non-privilegied user: docker run -it -v $(pwd):/app -u node node:lts-alpine /bin/sh

3. cd /app

4. corepack enable <-- This should fail

5. corepack prepare

6. pnpm install

首先，使用文档中针对 node:lts-alpine 的 Docker 命令以及非特权用户 -u node 重现该失败。检查镜像如何配置 Corepack 和可写路径；当 corepack enable 以 node 身份成功执行，并且文档中的 pnpm install 流程无需 root 即可正常工作时，即表示完成。
