have you ran scripts/install-sdk.sh?

[42yeah]

maybe you should try npm install?

@POTION4 I have tried to install npm install but I'm getting:

What could be happening?

This should do the trick:

rm -r node_modules/ 
npm cache clean 
npm install 
cd scripts/ 
./install-sdk.sh
cd ..
node server.js -p 8181 -l 127.0.0.1

"npm install" is the problem because it wipes out node_modules leaving only the few it installs by default and nearly none of those required by c9. Doing "npm i optimist" and the rest, will eventually leave you with a few that c9 needs but don't exist elsewhere. I heard someone mention they cp'd the node_modules folder and replaced it after running the npm install but other than that... there has to be a cleaner way to do this... also the install-sdk script runs an npm install of sorts but editing this file is pointless because it does this weird thing where it gets replaced with a tmp.

I was able to get the install script to run correctly and successfully by changing that crap bit of line "$NPM -production" to "npm install npm -g" (as basically a run once because the tmp replace) but of course it still wipes out the node_modules so maybe throw some "npm i"s in afterwards...

install-sdk.sh already does npm install so no need to run that separately
just tried with a fresh git clone, ./scripts/install-sdk.sh was all that was needed, worked just fine.
npm 6, node 8

I had this problem, and I fixed it by doing 2 things:

1. It was on a new Linux install, and I hadn't yet installed node/npm, so when the script ran npm install, it didn't. Perhaps the install script should error out in that case?

2. I kept getting a tmux error related to encoding. I added en_us UTF-8 as a locale, which fixed that problem.

After that, I ran the install script again, and it worked without an issue. Sounds like when this problem arises, something is halting the npm install, or exiting before it runs.

is it solved?

[wgailey]

I was finally able to uninstall and install a different way (which I had already tried when I posted previously) about a week later and it just worked.On Apr 14, 2020 8:13 PM, Laís Lima <notifications@github.com> wrote: is it solved? —You are receiving this because you commented.Reply to this email directly, view it on GitHub, or unsubscribe.
