Failed to upgrade

[carpben]

I followed the instructions. Openning Powershell as admin:

1. Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
2. npm install --global --production npm-windows-upgrade
3. npm-windows-upgrade

I get the following message:

npm-windows-upgrade : The term 'npm-windows-upgrade' is not recognized as the name of a cmdlet, function, script file,
or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and
try again.
At line:1 char:1
+ npm-windows-upgrade ....

This persisted after restarting the computer. Windows 10 version 1803, Node v 8.11.3, npm v 5.6.0

It looks like the folder npm's installs global stuff to is not on your path environmental variable(see npm-folders) . From powershell, if you run: dir $(npm -g bin) what is the output?

Mine is:

    Directory: F:\oo\bar\nvm\current\nodejs\nodejs

-a----       10/17/2018   4:50 PM            483 npx.cmd

then if I echo $env:Path, F:\oo\bar\nvm\current\nodejs\nodejs is on there. npm-windows-upgrade will be available to me to run in the current shell.

@virtuoushub, Sorry about the delay, and thanks for your reply!

I found a different solution to upgrade NPM.

In case it's still relevant, here is the result of running dir $(npm -g bin):

    Directory: C:\Users\carpb\AppData\Roaming\npm

When I run echo $env:Path I do find C:\Program Files\nodejs\;

@carpben How did you solve this problem?

[carpben]

It's been 6 months since I opened this issue. As far as I remember I found a different solution. I think I downloaded and installed node altogether, and it installed the latest version of NPM. @d41z

[carpben]

@d41z If you already have npm installed. Try "npm install -g npm@latest"

[d41z]

@carpben Ty for the reply! but finally i downloaded the last versión of node from web site.
