How can I update npm on Windows?

Answer 1

1. Installing latest npm version

npm install –g npm@latest 

(You can type "npm –version" to check that)

2. Installing Node

a. Install node new version via following URL: https://nodejs.org/en/download/current/ Follow the default choices
b. Remove C:\Users\\AppData\Roaming\NPM
c. Remove C:\Users\\AppData\Roaming\npm-cache

Optionally:

d. (Delete node_modules folder in your current project folder)
e. npm cache verify
f. npm install

Answer 2

OK guys, I read (tried on Windows) all the previous stuff and all of these answers have their own disadvantages.

For the best way to update Node.js (at least for me), go to https://nodejs.org/en/ Then download the last version and install it in same folder you installed the previous version in - 1 min and it's done. You don't need to remove any old files.

Then update npm typing in cmd: npm install --save latest-version

Answer 3

This is what worked for me.

1. Open a local folder other than the one in which nodejs is installed.
2. Install npm in that folder with command npm install npm
3. Navigate to the folder containing node js. (C:\Program Files\nodejs\node_modules)
4. Delete the npm folder and replace it with the npm and bin folders in the local folder.
5. Run npm -v. Now you would get updated version for npm.

Note: I tried installing npm directly in "C:\Program Files\nodejs\node_modules" but it created errors.

Answer 4

This might help someone. Neither "npm-windows-upgrade" nor the installer alone did it for me. Powershell was still using an older version of node and npm.

So this is what I did (worked for me): 1. Download the latest installer from nodejs.org. Install node. It will update your node; everywhere (Powershell, cmd etc.). 2. Install the npm-windows-upgrade package (npm install -g npm-windows-upgrade) and run npm-windows-upgrade.

I didn't uninstall anything and didn't set any paths.

Answer 5

Like some people, I needed to combine multiple answers, and I also needed to set a proxy.

This should work for anyone. I have zero desire to run an EXE file or MSI file .. uninstall/ reinstall, or manually delete files and folders. That is so 1999 :P

1. Run this to update NPM:

   Run PowerShell as administrator

   npm i -g npm    // This works
   

   I am not thinking this code actually upgrades your npm version below

   Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
   npm install -g npm-windows-upgrade
   npm-windows-upgrade

Run this to update Node.js:

wget https://nodejs.org/download/release/latest/win-x64/node.exe -OutFile 'C:\Program Files (x86)\nodejs\node.exe'    (courtesy of BrunoLM answer)

If you get `wget : Could not find a part of the path .... "**, see below ...scroll down. Reading Web Response... It's at least punching through the firewall /proxy (if you have one or have already ran the code get through ...

Otherwise

You might need to set your proxy

npm config set proxy "http://proxy.yourcorp.com:811"    (yes, use quotes)

2 possible errors

1. It cannot find path of the path solution "where.exe node" (courtesy of Lonnie Best Answer)

   E.g. if Node.js is NOT living in "Program Files (x86)" perhaps with where.exe, it is living in 'C:\Program Files\nodejs\node.exe'.

   wget https://nodejs.org/download/release/latest/win-x64/node.exe -OutFile 'C:\Program Files\nodejs\node.exe'
   

2. Now perhaps it tries to upgrade but you get another error, "node.exe is being used by another process."

   • Close /shutdown other consoles .. command prompts and PowerShell windows, etc. Even if you're using npm in a command prompt, close it.

npm -v (3.10.8)

node -v ( v6.6.0)

DONE. I'm at the version that I want.

Answer 6

I was also facing similar issues. I followed below mentioned steps and it worked for me:

• go to Windows > Start > Node.js

  • right click on Node.js command prompt
  • click on Run as administrator

• ping registry.npmjs.org

• npm view npm version

• cd %ProgramFiles%\nodejs

• npm install npm@latest

and npm updated successfully. Earlier I was trying for CMD and that was throwing error. may be some path issue that got resolved by running NodeJs Command Prompt. hope it'll work for you. try this.
