[Install Error] Error with "gulp install"

[timdoes]

Hi.

I am running into an error during the install on my mac.

npm install semantic-ui

Maybe jgoux/generator-angulpify#3 (comment)

I'd just recommend trying to clear node_modules if possible and re-install.

Thanks @jlukic

That fixed the first install problem. But now the install hangs.

Installing
------------------------------
Installing to semantic/
Copying UI definitions
Copying UI themes
Copying gulp tasks
Adding theme files
Creating gulpfile.js
Creating site theme folder /Users/user/Project/semantic/src/site/
Adjusting @siteFolder to:  site/
Creating src/theme.config (LESS config) /Users/user/Project/semantic/src/theme.config
Creating config file (semantic.json) /Users/user/Project/semantic.json
Install complete! Navigate to semantic/ and run "gulp build" to build
[10:32:53] Finished 'install' after 2.27 min

It hangs right after the line saying Finished 'install' for at least 20 minutes.

Then I hit Control + C to exit the process and Navigate to semantic/ and run "gulp build" to build and get the following error:

semantic(master) > gulp build
module.js:338
    throw err;
          ^

Thanks again for any help on this. It is much appreciated!

Peer dependencies unfortunately install after the install scripts finish. If you hit ctrl+c you are cancelling the peer deps install.

Are you on a particularly slow connection? Should be something like 49mb dl

[timdoes]

hmm... that's strange. My download speed is 120 Mbps. I guess I will have to manually install them.

Thanks for taking the time to look at this with me.

@jlukic I have experienced this issue before as well. I don't believe this "hanging" is the result of the installation of peer dependencies. During the initial install process, you must install Semantic UI via NPM, Ctrl-C after it starts hanging, navigate to node_modules/semantic-ui and run npm install, then navigate back to the semantic folder and run gulp build. Once these initial steps have been taken, upgrading Semantic UI will install peer dependencies correctly. During upgrades, instead of hanging, NPM outputs the installation status of the peer dependencies after Finished 'install'... appears. For some reason it only hangs during the initial install. Is there a particular reason why? I hope my explanation makes sense.

[jlukic]

What version/platform are you using with NPM? Just tried with blank dir in Ubuntu and had no issues getting through install.

[timdoes]

I am using:

1. OSX El Capitan version 10.11 Beta (15A215h)
2. node v0.12.7
3. npm v2.11.3

This fixed it for me (apparently gulp could not run because node was not in the $PATH): nodejs/node-v0.x-archive#3911 (comment)
