Common Errors

  • Error: Can't resolve '../build/contracts/LoopringToken.json'

This means you haven't compiled or migrated your contracts yet. Run truffle compile and truffle migrate first.

Full error:

ERROR in ./app/main.js
Module not found: Error: Can't resolve '../build/contracts/LoopringToken.json' in '/Users/tim/Documents/workspace/Consensys/test3/app'
 @ ./app/main.js 11:16-59
  • Error: "/usr/bin/env: node: No such file or directory"

If you have installed nodejs from your package repo in ubuntu it is called nodejs and not node. You can solve it whit a symlink creation:

ln -s /usr/bin/nodejs /usr/local/bin/node
  • Error: "TypeError: this is not a typed array" or "TypeError: path must be a string"

Check your node version, and upgrade it if under 8.0.0

e.g. install node 8._ in Ubuntu:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
