I'm using windows 8.1 x64 with all updates.

I was using nodejs 8.9.1 - I took an error on mand "npm -v".
So I uninstalled this version and install 8.9.3. It gave me same error on the mand.
And then I uninstalled 8.9.3 and clean all paths using this answer; Then installed new version 9.3.0...

But still, I'm getting same error in all npm mands.
What am I missing? How can I solve this problem?

I ran out all options and I have still a lot work to do with npm packages. So, I've formatted my machine and replace with Windows 10 Enterprise x64. I can't try new answers now but here is golden point what I've learned; If you have mission critical machine like ci-build (jenkins etc.) or if you don't have more than one puter (And vm is not an option) Just backup your drive pletely at time to time because you will never know your puter softwares (like node - npm) could give an interesting errors such as this.

• Are you administrator? Try installing node using nvm for Windows or nvs. – gretro Commented Dec 24, 2017 at 16:49
• @gretro thanks for suggestion. I tried all installs with administrator. Also I tried nvm - no luck. Still I'm getting same error message. – Lost_In_Library Commented Dec 24, 2017 at 17:33
• Is any other version working? Like Node 6 or something? – gretro Commented Dec 24, 2017 at 17:35
• I only tried 3 versions. 8.9.1, 8.9.3 and 9.3.0. Also I checked my antivirus and firewall settings (everything seems fine). node -v mand is working and giving version number. But npm -v mand giving this (ENOENT) error message all the time. I didn't try node v6, because it will mess up the environment more some-how. I don't know. Do you remend it? I can try if you really think it will help. – Lost_In_Library Commented Dec 24, 2017 at 17:41
• 1 If node -v is working and not npm -v, it probably means that you need to add the variable name npm in your variable environment. You can consider this answer – edkeveked Commented Dec 24, 2017 at 17:45

The workaround is to ensure that C:\Users\{user}\AppData\Roaming\npm exists and is writable with your normal user account.

see Troubleshooting

Although haven't tested Node on Windows 8, I suggest you get rid of npm installation under AppData folder altogether. You can achieve this by using a Node version manager. I remend Nodist. You can easily switch between versions as well.

With Nodist you can run the mand as such:

 nodist 6.2.10

One of the things I suspect is Node runtime's limited access to required files under C:/ drive - maybe something related to Windows 8. That said, you could install nodist in any drive other than C:/. Meanwhile as mentioned by @fjoe, stick with LTS versions especially v6.x.x.

Here are a few things to consider when picking your node.js version.

Version labelled as LTS (Long Term Support) are the releases they stand behind.

You can see a full list of versions here notice the LTS column. It is also interesting to see the versions of V8 and npm that are packaged with each.

• Node 9.* has no official LTS release.
• Node 8.* officially entered LTS on 10-31-2017 (3 months ago).
  • I personally have run into problems with it.
• Node 7.* never officially released as LTS.
• Node 6.* has 2 years of official LTS releases and they are continuing to support it.
  • With the most recent release on 01-02-2018.

Given this information might I remend you try the proven long supported version 6.*

If this works then maybe hold off on version 8.* until more things get ironed out.

Other people have mented on your question about environment variables for node or npm. This is obviously not the issue as the mands are recognized and running (but they error).

Also I would remend you follow this full uninstall guide: How to pletely remove node.js from Windows

My coding buddy had a similar error yesterday, although on Linux.

The error was in the node_modules folder, so removing that and reinstalling node solved it for him.

That would be your node_module folder in AppData\Roaming\npm.

I guess the problem can be in NPM itself. try to update your NPM.

Try to use this great approach

By the way, it's great to know what npm version you have with your changes of node.js versions.

From the logs you provided it looks like a cache bug, because of some junk that previously exists and that is causing issues.

Open the mand prompt with admin privileges and follow the below steps:

1) Clear the cache: npm cache clean --force. You can also run npm cache verify.

2) Delete node_modules folder using: rm -rf node_modules.

3) Delete any package-lock.json file.

4) Remove the .npm directory.

5) Remove following directories :

   5.1) C:\Users\<username>\AppData\Roaming\npm\. 

   5.2) C:\Users\<username>\AppData\Roaming\npm-cache.

6) Also, Try by setting environment variables:

C:\Users\<username>\AppData\Roaming\npm;C:\Program Files\nodejs.

Type in the mand line: which npm.

Maybe you did not set the system value : NODE_PATH it should point to your global module location.

7) Update to the latest npm with npm i -g npm@latest.

Hope the above trick resolve your issue.

Thanks.

I guess while installing Node.js it don't able to set it's environment path due to permission.

You Need to configure Node path manually into environment variables.

try:

npm init react-app myapp(noun)
