Given a package.json file with several optionalDependencies such as the following:

I’m facing an issue when trying to run npm install on my server. Here’s the error message I’m receiving.

I would like to publish a NPM package with a CLI utility in it. In the package.json, I have the following line:

npm ERR! code EPERM
npm ERR! syscall mkdir
npm ERR! path D:Node Jsnode_modules.npm-Pmxry05m
npm ERR! errno -4048
npm ERR! Error: EPERM: operation not permitted, mkdir ‘D:Node Jsnode_modules.npm-Pmxry05m’
npm ERR! [Error: EPERM: operation not permitted, mkdir ‘D:Node Jsnode_modules.npm-Pmxry05m’] {

npm ERR! path: ‘D:Node Jsnode_modules.npm-Pmxry05m’
npm ERR! }
npm ERR!
npm ERR! The operation was rejected by your operating system.

Note: I have gone through similar questions and have tried all possible solutions posted, but this is still an issue for me. I have downgraded my node to v16, v18, v20 and but still same issue exists. Its still not clear for me from the error whats wrong.
