having trouble installing ethersim from NPM, any thoughts?

[iurimatias]

what version of npm and node do you got? it seems to be some permissions issue e.g npm/npm#3664

[SilentCicero]

I'll run an update, if I still get the same errors I'll run it by you.

[iurimatias]

@SilentCicero just released a new version with a lots of npm issues fixed. please let me know if you are still having issues

@iurimatias I figured out why Embark is failing to install on OS X.

EtherSim is using an outdated version of ethereumjs-vm. The latest version of ethereumjs-vm is 1.0.1, and it has the latest secp256k1 with the fix for OS X.

Unless there are other uncaught outdated dependencies, addressing this should fix:

• Error when installed using NPM ethereumjs/ethereumjs-tx#6
• npm install errors embarklabs/embark#99

EDIT: Since this is different from what @SilentCicero describes, I've opened #2.

We really need to update NPM with what's on develop. :)

[iurimatias]

released 0.2.0 with the latest changes

Tried to npm install -g EtherSim, still fails due to unfixed secp256k1 versions:

[email protected] install /usr/local/lib/node_modules/ethersim/node_modules/ethereumjs-vm/node_modules/secp256k1

[email protected] install /usr/local/lib/node_modules/ethersim/node_modules/ethereumjs-block/node_modules/secp256k1

I'm getting a recent version of secp256k1 when installing from npm today. So this issue might be closed?

End result of npm install -g ethersim:

Yep, I can confirm that this works now (and installs an insane amount of dependencies).
