pnpm包管理器的配置

规范管理全局包 / 缓存
1.手动新建E:\software\node_global 和 E:\software\node_cache
2.在E盘下执行

npm config set prefix "E:\software\node_global"
npm config set cache "E:\software\node_cache"

3.重启终端，在E盘下执行：npm i pnpm -g，整个系统可用

npm error The operation was rejected by your operating system.

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.
npm error Log files were not written due to an error writing to the directory: E:\software\node_cache\_logs
npm error You can rerun the command with `--loglevel=verbose` to see the logs in your terminal

原因：遇到的 EPERM 错误是权限问题—— 系统禁止 npm 在 E:\software\node_cache 目录下创建文件夹，这是 Windows 很常见的权限报错

解决
win+r以管理员身份运行终端

PS C:\Users\吴旭烨> E:
PS E:\> npm i pnpm -g

changed 1 package in 14s

1 package is looking for funding
  run `npm fund` for details

但是在pnom -v的时候出错

PS E:\> pnpm -v
pnpm : 无法将“pnpm”项识别为 cmdlet、函数、脚本文件或可运行程序的名称。请检查名称的拼写，如果包括路径，请确保路径正确
，然后再试一次。
所在位置 行:1 字符: 1
+ pnpm -v
+ ~~~~
    + CategoryInfo          : ObjectNotFound: (pnpm:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

解决
右键「此电脑」→「属性」→「高级系统设置」→「环境变量」(或者win+r键入：sysdm.cpl)；
在「用户变量」的 Path 里，确认 E:\software\node_global 已经存在（没有的话自己添加）；
如果存在但仍报错，把 E:\software\node_global 「上移」到 Path 列表的最顶部（提升优先级）；
点击「确定」保存，后续新开终端就会自动识别 pnpm 了。
