Upgrading npm (fallback method)...

You wanted to install npm 6.13.4, but the installed version is 6.9.0.

A common reason is an attempted "npm install npm" or "npm upgrade npm". As of today, the only solution is to completely uninstall and then reinstall Node.js. For a small tutorial, please see https://github.com/felixrieseberg/npm-windows-upgrade#usage.

Please consider reporting your trouble to https://aka.ms/npm-issues.

Debug Information:

node: 12.6.0 | v8: 7.5.288.22-node.14 | uv: 1.30.1 | zlib: 1.2.11 | brotli: 1.0.7 | ares: 1.15.0 | modules: 72 | nghttp2: 1.38.0 | napi: 4 | llhttp: 1.1.4 | http_parser: 2.8.0 | openssl: 1.1.1c | cldr: 35.1 | icu: 64.2 | tz: 2019a | unicode: 12.1 | os: win32 x64 | OS Name: Microsoft Windows 10 Enterprise
OS Version: 10.0.17134 N/A Build 17134

Steps to reproduce the problem:

I would like to get the latest npm package 6.13.4 [no security issues] with node version 12.13.1

This worked for me, but I won't swear by it as the answer for everyone:

1. Use nvm install to set up the node installation.
2. Execute nvm use to set the current version.
3. Open it the current version in File Explorer. (From PowerShell, you can do this with explorer.exe $env:NVM_SYMLINK. From Command Prompt, it's explorer.exe %NVM_SYMLINK%.)
4. Delete the npm, npx, npm.cmd, and npx.cmd files. I don't think there were any ps1 file when I set it up, but it so, delete those, too. Careful. I don't know the full effects of this deletion if the upgrade fails. You should either keep them in Recycle Bin so you can restore them or be prepared to do a full reinstall of the Node version if it fails.
5. Now that the script is deleted, we have to invoke npm a bit more manually. Here's the PowerShell command to invoke its update command:
   node (Join-Path $env:NVM_SYMLINK 'node_modules\npm\lib\npm.js') install -g npm

This worked for me because when I ran npm install -g npm, the error I was getting was that the top level script files were "outside" the installation, which I assume means that they weren't recognized as managed by it. I don't know why npm thought it didn't control those files, but once they were out of its way, it updated just fine.

This works as well. https://github.com/coreybutler/nvm-windows/issues/300#issuecomment-571237846

@myty Again, I can't speak for everyone, but npm-windows-upgrade failed miserably for me. Its error message was even more cryptic and unhelpful than the one I got from npm install -g npm. (I don't recall the exact error message; I think it was just extremely generic.) It's possible we were facing different issues, though.

This has worked for me in the past, but now ,whilst trying to update npm from 6.13.4 to 6.13.6 (using node 12.16.0), I get the following error:

Anybody else hit this issue and been able to resolve? I did try with --force but same error.

I had Nodist installed prior to nvm-windows. It left a .npmrc file under home directory (%userprofile%). I had to remove it and try nvm use command again to get everything right.
