全局安装 npm 包时出错，npm ERR！代码 ENOENT

我正在尝试以全局方式安装 nodemon 和 browserify，但我不能。它显示错误

npm ERR! code ENOENT
npm ERR! syscall lstat

npm ERR! errno -4058
npm ERR! enoent ENOENT: no such file or directory, lstat 'C:\Users\vignesh\AppData\Roaming\npm'
npm ERR! enoent This is related to npm not being able to find a file.

npm ERR!     C:\Users\vignesh\AppData\Local\npm-cache\_logs\2021-07-02T09_36_20_737Z-debug.log

但是我可以安装 devDependencies 并且我不能运行 browserify。请一些人帮忙
