Truffle: Cannot find module 'truffle-expect'

Created on 1 Jul 2017 · 14Comments · Source: trufflesuite/truffle

[x] I've asked for help in the Truffle Gitter before filing this issue.

Issue

Made a fresh truffle install today (my first). When using truffle migrate with the 'truffle init' project I get an error saying cannot find truffle-expect. Error remained after doing:
sudo npm install -g truffle-expect

Steps to Reproduce

new install of truffle
npm install -g truffle
mkdir newproj
cd newproj
truffle init
truffle compile
truffle migrate

Expected Behavior

no error

I posted the "fix" above but it sounds like this issue has been resolved just not deployed yet. You can follow the accepted answer in that StackOverflow.com question in the meantime to resolve the issue using -

$ npm install -g truffle-expect truffle-config web3

Even after running npm install -g truffle-expect truffle-config web3 I still cannot execute truffle migrate cmd.

It still fails with:
Cannot find module 'truffle-expect' at Function.Module._resolveFilename (module.js:485:15) at Function.Module._load (module.js:437:25) at Module.require (module.js:513:17) at require (internal/module.js:11:18) at Object.<anonymous>.

It's very strange as I see all packages (truffle-expect, truffle-config and truffle) in my npm-global directory at /Users/username/.npm-packages/lib/node_modules/...
I tried to re-install truffle-expect, truffle-config and truffle globally several times, but it has no effect. My OP is Mac OS Sierra, I'm using npm/node installed via homebrew.

@egortsaryk9
same as you, after running npm install -g truffle-expect truffle-config web3 still has the error Cannot find module 'truffle-expect'

I'm on windows and I can't install truffle-config. web3 and truffle-expect installed just fine, but config errors out.

rogeriosmorais on 6 Jul 2017

It was my bad. I had 2 versions of truffle, the old 3.3.1 at /Users/username/.node/bin/truffle and the newest 3.4.5 at /Users/username/.npm-packages/bin/truffle. So truffle were linked to 3.3.1 path that didn't contain all required packages. Make sure you have correct paths if you use homebrew (https://gist.github.com/DanHerbert/9520689)

This seems pretty old and likely out of date. Closing, but let me know if the problem still persists on newer versions of Truffle and I will reopen. Thanks!
