I upgrade to node 0.4.1 and now I'm getting ...

Could not find the coroutine shim!

from node-fibers.

Could you tell me a bit more about your setup? Do you have a ~/.npmrc? Where do you have node installed? Could you see if you could find coroutine.so somewhere in your node directory?

Have you tried the latest version of fibers in npm? There's some improvements there which may help you.

If not, take a peak at the node-fibers script yourself (cat which node-fibers), it's fairly short. Basically it needs to find coroutine.so which is created when you install fibers. It sounds like there's something weird about your config and coroutine.so is getting put in a place node-fibers can't find.

from node-fibers.

I found that starting it with /usr/local/bin/node-fibers instead of just node-fibers works. My original problem is gone now also. So I'm good to go.

What do you think is going wrong when I just use node-fibers?

from node-fibers.

Interesting, I'm not quite sure what's gonig on. Does which node-fibers return "/usr/local/bin/node-fibers"?

You're running fibers 0.2.2 from npm? [email protected] has improved fiber-finding logic. Anyway if you're good to go I'll close this out. If you could troubleshoot it more and find out what happened it would be useful for other people using fibers, but don't feel obligated.

from node-fibers.

Yes to both questions. Which gives /usr/local/bin/node-fibers and it is 0.2.2. If/when I have some free time I'll do more experimenting. I only start node from scripts so this problem doesn't bother me.

P.S. If this works as advertised I predict I am going to be a happy camper. I've used continuations in Python and love them. I'm very comfortable typing run and yield and I don't understand why people think they need higher level wrappers.

from node-fibers.

I spoke too soon. The shim problem is back. So here are the answers to your questions...

I have no ~/.npmrc.

The only node folder with bin, lib, etc that I could find was in /root/local/node.

I searched the entire disk and coroutine.so is at three places:

/usr/local/lib/node/.npm/fibers/0.2.1/package/src/coroutine.so
/usr/local/lib/node/.npm/fibers/0.2.2/package/src/coroutine.so
/root/local/node/lib/node/.npm/fibers/0.2.2/package/src/coroutine.so

The /usr/local/bin/node-fibers script is a bit over my head so I can't really debug it. If I have to I will decipher it.

from node-fibers.

Perhaps try uninstalling both versions of fibers and reinstalling? It could be calling the old 0.2.1 node-fibers script instead.

It seems like "/root/local/node/lib/node/.npm/fibers/0.2.2/package/src/coroutine.so" would be a symlink to "/usr/local/lib/node/.npm/fibers/0.2.2/package/src/coroutine.so" or vice versa.

Without actually looking at the environment it's difficult for me to understand exactly what is failing. Other users have had luck installing fibers on different distributions of Linux, and OS X.. so it seems to be something peculiar of your installation.

Based on the information you posted you could probably get fibers running by doing:
FIBER_SHIM=1 LD_PRELOAD="/usr/local/lib/node/.npm/fibers/0.2.2/package/src/coroutine.so" node <myscript.js>

But that would be a hack until you could figure out why node-fibers isn't finding coroutine.so on its own.

from node-fibers.

Your hack is working. The next time I need to upgrade anything I'll completely wipe node and fibers and install from scratch.

If leaving this hanging bothers you, I'd be happy to let you log in and look around.

from node-fibers.

I'm ok leaving it this way for now. Do let me know if reinstalling doesn't solve the issue, or if you find out what the original issue was.

from node-fibers.

Unfortunately with latest node node-fibers wrapper fails again, it's a node bug (nodejs/node-v0.x-archive#755).

from node-fibers.

I'm not seeing any hard failures, just broken pipe errors. The script still works. Could you pull and let me know if 1b31427 helps?

from node-fibers.

OK, seems to work fine with latest npm, but with npm 2.x I was getting "Could not find the coroutine shim!" beside EPIPE. Not sure why.
