Thanks to Kshitij's answer at another page! but I still have this error after applying this answer. which drives me crazy! Sorry for post the question as a answer-_-

After run truffle init and truffle compile, it works fine. the contracts that I compile are examples from truffle:(when I change to HelloWorld it's the exactly same error)

  • ConvertLib.sol MetaCoin.sol Migrations.sol

other information is:

  • ubuntu 14.04.2
  • node -v v7.10.0
  • npm -c 4.2.0
  • Truffle v3.3.2 (core: 3.3.1)
  • Solidity v0.4.11 (solc-js)

Every time I run "truffle migrate" it shows Error, with or without testrpc running

error message:

Error: Cannot find module 'truffle-expect'
    at Function.Module._resolveFilename (module.js:470:15)
    at Function.Module._load (module.js:418:25)
    at Module.require (module.js:498:17)
    at require (internal/module.js:20:19)
    at Object.<anonymous> 

installing truffle-expect won't work, would anyone give me a hand please?

This is a known issue and I'm sure truffle will have a fix for it very soon.

Workaround 1

For now, try running npm install -g truffle-expect truffle-config web3, which seems to work for several people.

Workaround 2

If that doesn't work for you, try installing an earlier version of truffle until the fix is applied.


npm i -g [email protected]

    I tried both of 1&2, it still has the Error cannot find module 'truffle-export', but thanks anyway

  • hmm, you're probably using truffle globally, so it was my mistake in number 2. Try running npm un -g truffle to uninstall, then my updated command above to install earlier version again (includes -g flag). Commented Jul 6, 2017 at 3:42
  • I'm sure I had to close and open the console window after installing, thought I'd mention it in case that was your issue

  • thanks you guys, after running 'npm un -g truffle' to uninstall & 'npm i -g [email protected]' to reinstall 3.2.2 version. I found my truffle version is still 3.3.2. (And I close and open the console window after installing)
