gh-pages -d build events.js:174. throw er; // Unhandled 'error' event

[ahmedgulabkhan]

Installed gh-pages as dev dependency in my react project. The below error is displayed everytime I run the command npm run deploy to deploy the app to github using gh-pages.

Error:

Searched for some help online, and downgraded react-scripts to version 2.1.8. But the issue is still not resolved.

Having the same error, trying to run this in Jenkins.. I'm trying to publish the results of a CompDoc generation for an Angular library.

Everything works if I run from my local.

Our Jenkins scripts are set up to run npm inside a docker image, I believe. It successfully checks out the repo, so it has access, but was thinking that gh-pages could not find the git info.

I added "C:\Program Files\Git\bin\git.exe" and "C:\Program Files\Git\cmd" to my system variables and it fixed the problem for me.

INSTALL/REINSTALL GIT Update NPM Reopen EDITOR

this solved my problem

[ahmedgulabkhan]

@SystemDZ I followed these steps even before raising the issue, it didn't solve the problem

[SystemDZ]

@ahmedgulabkhan try start from all over again following a video on youtube that shows you step by step, you must be making a mistake some where in the process.

probably pulling at straws here, but regarding this working on localhost and not on jenkins, do you know if the same version of node is running in both environments, or if using nvm, potentially you have the proper version of node installed and its merely not configured to be using the proper version??? I haven't had issues with this, but quite recently had an issue with a different node package not working in a different environment, and the node version was indeed the issue
