Gatsby: gatsby: command not found after npm install

[marieqg]

When I try to install gatsby running npm install 'gatsby-cli -g' , it does not work : when I run 'gatsby --help', it shows:
'bash:gatsby command not found'

I have tried:
1) uninstalling and reinstalling NPM
2) this gitHub solution : https://github.com/gatsbyjs/gatsby/issues/4967
I get a permission error when trying to change npm config set prefix /usr/local
3) Uninstalling and reinstally Gatsby

I'm working on mac (version 10.14.5).
My environment details are as follows:
npm -v : 6.9.0
node -v : v10.16.0

As for permission, I already have an "export PATH=~/.npm-global/bin:$PATH" in a .bash_profile that is in my ~/.npm-global folder (https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally).

What can I do to make it work?

Thanks in advance,
Marie

It does seem like globally installed packages for some reason not work in your environment :/

Here's another article worth to go through: https://medium.com/@jagatjyoti.1si13cs040/npm-g-install-npm-package-not-working-as-desired-why-why-why-19795abf0b59

If this won't help, there is workaround this that you can try - instead of trying to install and use globally installed gatsby-cli, you can use npx:

npx gatsby new <directory_name>
npx gatsby develop
npx gatsby build

etc. or add commands to scripts in package.json:

"scripts": {
  "develop": "gatsby develop",
  "build": "gatsby build"
}

and run them with

npm run develop
npm run build

Thank's a lot! I solved my problem :) It was a global installation problem indeed!
I followed the github solution ( #4967) but did a "sudo npm install gatsby-cli -g –"

I know this is an older post, but being that it showed up first in my search I figured I'd share my solution.

My global packages on my Windows10 (Work machine, I'd much rather a Mac) are set to install at the below path.

/c/Users/{username}/AppData/Roaming/npm

So I added this to my PATH variable and now it finds the installation. You can search for "Environment Variables", click Path and add the path there, or if you're like me and don't have admin rights you can add via Git Bash in Windows like below.

PATH=\$PATH:/c/Users/{username}/AppData/Roaming/npm

You can also create an Bash alias and have it automatically run when you start Git Bash.
