Hey guys! I hope to find some help here even though this room didn't seem to have much life in last 5 months or so :) I'm trying to run a node script on a service startup (Ubuntu 12.04): it's been running alright this way before I started using nvm:

exec sudo -u strider <script>

Unfortunately, it seems that $PATH is the one of a root user when the command is run like this meaning that bash sees neither the script nor the node executable.

I feel so stupid right now, as it seems like an issue that must've already been solved so many times, but I still can't get it working as well finding anything helpful on the matter. Maybe someone can point me at how it can be done?

@ljharb

@glock18 yes, nvm is per-user, so it's not compatible with sudo

so if you want root to have nvm, it needs its own installation of nvm, and your script probably will need to source nvm.sh

glock18

@glock18

@ljharb thank you for response. No, of course I don't want to run any of this as a root user. For now I'm gonna be passing right PATH to the command, which might be not-to-good of a solution, but at least it doesn't require shenanigans with multiple installations of nvm, node or whatnot.

Jordan Harband

@ljharb

@glock18 makes sense. ideally the script wouldn't need sudo at all tho :-)

howdy

running nvm in a makefile in a docker container,

I've pieced together this command: bash -l -c 'source ~/.nvm/nvm.sh; nvm install; npm install; npm run build'

it gets the job done, but checking for glaring pitfalls my team might run into using this

Jordan Harband

@ljharb

@charginghawk you've now asked in 3 places :-) cross-posting doesn't help much. let's continue in #nvm on freenode.

Hello everyone, i tryed the web, but was not able to find anything.
"Using nvm in a Makefile"
doable or no?

and how :)

Jordan Harband

@ljharb

@filip94 i don't see why it's not doable; but nvm works by modifying the PATH, and make tasks don't share the same shell session as the one that make was invoked from

Anyone know how to select an architecture with NVM? Using a service that cross compiles and wraps up a raspberry pi docker images, and the builder cannot find latest binaries for armv8, so it tries to compile which takes forever. I want to choose armv6

@charginghawk I am using this currently in my dockerfile:<code> ENV NVM_DIR /root/.nvm
ENV NODE_VERSION 8

RUN curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash \
&& source $NVM_DIR/nvm.sh \
&& nvm install $NODE_VERSION \
&& nvm alias default $NODE_VERSION \
&& nvm use default \
&& npm install http-server </code>

Jordan Harband

@ljharb

@sako0938 there's no "select an architecture"; if nvm won't install on your arch, and there's no node compiler flags that can make it do so, then your arch isn't supported by node

Sam Korn

@sako0938

My architecture is supported, ended up just not using nvm and including the lts binary for my architecture within my repo. My problem is related to having a different system building the image than actually running it.

Jordan Harband

@ljharb

ah. yeah that's just always going to cause problems

your build machine should always be identical to your production machine, for tons of reasons

hi guys, I have the strangest problem, really perplexed; I'm using something like the following to attempt to check if the current node version is set to what I have in an ansible playbook.....

i.e. this should exit code 0; nvm ls | grep -e 'default -> v8.9.3'

('cause I have v8.9.3 set as the default right now)

➜ nvm ls                           
         v8.9.3
default -> v8.9.3
node -> stable (-> v8.9.3) (default)
stable -> 8.9 (-> v8.9.3) (default)
iojs -> N/A (default)
lts/* -> lts/carbon (-> v8.9.3)
lts/argon -> v4.8.7 (-> N/A)
lts/boron -> v6.12.2 (-> N/A)
lts/carbon -> v8.9.3

anyone have any ideas? I really want this role to be idempotent, and need to figure this, if anyone has any ideas, I'd love to hear 'em ;)

Jordan Harband

@ljharb

@willwh nvm alias default will print it out directly

@willwh however i think the issue might be that terminal colors are messing it up. try TERM=dumb nvm alias default

(that shuts off the colors)

William Hetherington

@willwh

welp, that's pretty awful

thank you so much for the help @ljharb :)

that sorted me right out!

that should probably make it in the Readme.md want a PR?

;)

Jordan Harband

@ljharb

sure, you mean like a general section about terminal colors?

also that nvm alias x prints out what "x" is :-)

nvm --help should also probably say those things if it doesn't already

@willwh a PR would be great :-)

William Hetherington

@willwh

@ljharb groovy, am at work right now, with deadlines, I promise I will crank something out over the weekend though

Jordan Harband

@ljharb

sounds great

William Hetherington

@willwh

thanks so much, again! :)

I made myself a reminder ;) creationix/nvm#1693

hey how to use nvm for windows

Jordan Harband

@ljharb

@jimmyYSY nvm only works on windows if you're using the linux subsystem

jimmy · YIN

@jimmyYSY

@ljharb sorry I don't quite understand

Jordan Harband

@ljharb

@jimmyYSY windows 10 has a thing called "BashOnWindows", or "the linux subsystem", which gives you a unix-like command line interface. that's required to run nvm on windows; otherwise you'll need a different software projecct.

jimmy · YIN

@jimmyYSY

@ljharb ok thanks i will try again

Does nvim run OK on Windows' bash? I joined a company to work with C# after a long time away from Windows, so I'm not sure if it's worth the trouble trying to use nvim on it

Jordan Harband

@ljharb

it should work fine

Ricardo Oliveira

@rgoliveira

Ok, thanks. I tried out nvim-qt and it's kinda ok for me, but I prefer to use it on the terminal

Oh, crap, I thought I had joined neovim's gitter 😂
