Lesson 7: EIO: i/o error while installing packages

[Olaleye-Blessing]

Error: An unexpected error occurred: "EIO: i/o error, unlink '/mnt/c/Users/Jongbo/Documents/Web 3/hardhat-fund-me/node_modules/keccak/prebuilds/win32-x64/node.napi.node'".

I got the above error while trying to install solhint. I got the same error last month while trying to install some packages in chapter 7 but I could find some of the packages in node_modules.

Is there a possible fix for this?

Thats some system errors.

See this bro: yarnpkg/yarn#4455
& this: npm/npm#17030

Restart your computer, if it still doesn't work then try some solutions from the given comments on the above posts.

I also used to get these errors in yarn, then I switched to NPM, and now I don't get these errors anymore (Alhumdulilah).

Check this: #479

& this aswell: #431

Follow the steps below: ("oldprojectname" here refers to your current projects name)

• Create a new directory named "oldprojectname_2" (preferably in the parent directory where you have everything)
• In the old project, right click on any folder > show in explorer.
• Then, copy everything EXCEPT node_modules into the new project, ie, "oldprojectname_2".
• Delete old project.
• Now, rename the new project to "oldprojectname"
• Now, open up that new project in VSCode/IDE and in the terminal, do yarn install.
• This should fix it.

Cheers!

@Olaleye-Blessing Delete the node_modules folder, update to latest version of npm, and reinstall dependencies.

Should work, but personally I find it safer to just make a new directory, doesn't take much time either.

@krakxn Yes krakxn, but due to the older version he can again face the same issue and similar other issues, so it would be better to target the main issue that resolves all other itself.

Fair enough!
