Is this using powershell? (The issue does ask but it's not clear from your answer so hard to debug)

[Alchemistst]

I have been having this issue as well. I'm ussing powershell 6 (also tried with powershell 5.1 and got the same result).

As OP mentions, this is what I've done:

`
npm init
`
Everything goes all right. Then I execute:
`
npm install nodemon --save-dev
`
And the output I get is this:
`
> node bin/postinstall || exit 0

I have previously used nodemon (a month ago probably) in another project through this exact same install command and everything worked fine. Now, in that project, deleting the node_modules folder and running npm install yields the same output as above.
It seems there's something wrong with the command node bin/postinstall || exit 0
'||' is not a powershell operator.

I'm glad to give any more details if needed.

Needs to run on windows to investigate alternative fix.

[remy]

I can't replicate this at all. I've provisioned a Windows 10 machine from AWS and connect to it using Windows Remote Client, then go through the motion.

Attached is a screenshot of Powershell running the postinstall command, without error and I'm on a 5.x version of PS.

If anyone is able to replicate this in a parred down example and able to offer a fix to the || statement, I'd love to hear about it.

I'll leave this open for the time being, but if it remains inactive, it'll close by itself (I hope that's fine).

[ttomm]

I have the same problem.
I use Windows 10, I have Nodemon installed globally in version 2.0.3, but when I try to install Nodemon locally, in project folder, I get the same error

So I downloadad Nodemon from https://github.com/remy/nodemon as a zip file and unpacked next to my project folder , after that I removed || exit 0 from package.json and from my project folder I ran command

npm install ../nodemon-master

This not-very-elegant workaround works.

[remy]

And what if you do what I did and run the npm script directly? (In the name of solving this issue)

I ended up switiching to Linux. Definitely not the best solution, but had the chance to do it and did it. Working seamlessly on Linux.

Same error with me

[remy]

I tried to replicate this and could not. And since no one was posting any pull requests to fix it, it'll close itself and won't be fixed.

I'm going to close this and encourage anyone who is able to replicate to offer a solution that allows the OR exit 0 to run cross platform. Thanks in advance.

[FieryRMS]

Hi all,
I managed to fix it sort of, run the following commands in order,

npm config set script-shell cmd

npm i nodemon

npm config set script-shell powershell

and for anyone trying to replicate the problem, run, npm config set script-shell powershell before npm i nodemon
hope it help!

@ArmaanTechDeveloper did you try the fix (literally the last comment): npm config set script-shell powershell?
