pnpm 的安装源太多了，感觉系统变量都有引入顺序。

今天踩坑记录：
pnpm ，如果最初用npm 装的，可以用npm 升级；
如果最初用brew 装的，得用brew 升级；
如果最初是用corepack 装的得用corepack 升级；

由于项目需要，我今天直接：npm install -g pnpm@10.12.4

然后，就 Error: EACCES: permission denied, access ‘/usr/local/lib/node_modules’

在这里插入图片描述

npm install -g pnpm@10.12.4

npm error }
npm error
npm error The operation was rejected by your operating system.
npm error It is likely you do not have the permissions to access this file as the current user
npm error
npm error If you believe this might be a permissions issue, please double-check the
npm error permissions of the file and its containing directories, or try running
npm error the command again as root/Administrator.

改变文件的权限：

First check who owns the directory

ls -la /usr/local/lib/node_modules

请添加图片描述

它拒绝访问，因为节点模块文件夹归root所有。
因此，需要将root更改为您的用户，但首先运行下面的命令来检查当前用户

在控制台输入：id -un OR whoami
然后去改变owner

sudo chown -R $USER /usr/local/lib/
sudo chown -R $USER /usr/local/bin/
sudo chown -R $USER /usr/local/share/

再检查文件所属权：

然后我再执行 sudo npm install -global pnpm

呃，这。
脑子里忽然闪过一丢灵光，感觉是系统变量引入顺序的问题。我看公司的这台电脑里是装了brew 和 corepack 的
我就试了试：brew 结果和 npm 升级 pnpm 一样。

最后我试了试corepack

corepack enable pnpm
corepack use pnpm@latest-10

然后就好了

pnpm -v
10.12.4

然后我开始装包：pnpm install
pnpm install gives no such file or directory, mkdir '/home/vsts error.

 ENOENT  ENOENT: no such file or directory, mkdir '/home/vsts'pnpm: ENOENT: no such file or directory, mkdir '/home/vsts'at async Object.mkdir (node:internal/fs/promises:859:10)at async createNewStoreController (/Users/edy/.cache/node/corepack/v1/pnpm/10.12.4/dist/pnpm.cjs:101790:7)

通过搜索找到答案：手动设置路径：pnpm config set store-dir /path/to/pnpm/store/v3.
Make sure that the path actually exists.

设置路径后，再次装包

pnpm no such file or directory, mkdir ‘/path’
