Web3.js: Keccak256 Unexpected Token on Linux/ElementaryOS Loki using Node 0.8.4

[johannesleander]

Using Node, I'm trying to import web3.js as a dependency using Node in Terminal. When doing so, Node throws Unexpected Token over a line in the web3 code and I'm unable to find any other instance of users having the same issue.

Terminal I/O is the following:

elem@elem-lean:~/Projects/testProjectg$ node
> Web3 = require('web3')
/home/elem/Projects/hello-world-voting/node_modules/web3/packages/web3-eth-accounts/node_modules/eth-lib/src/account.js:6
const {keccak256, keccak256s} = require("./hash");
      ^
SyntaxError: Unexpected token {

~i am assuming your node is to old and doesn't support ES6.~
@MaiaVictor is there a way to transpire your project before its used by other projects?

EDIT: I see youre using 0.8.4,then i am a bit confused what could be the problem here.

[MaiaVictor]

Sure, [email protected] is transpiled now. Please message me directly when something like that is needed. (I won't be paying attention to issues until next month.)

[frozeman]

Please see if the next release beta.17 will fix this for you. If so please close.

@MaiaVictor i add your new version but still get the error, e.g. when adding it to a meteor app backend with no babel enabled:

It's still an issue. Reverted back to an old version.

[bellaj]

same issue on ubuntu and nodejs
it works if i use 0.20 version npm install web3@^0.20.0

[AndreyPatseiko]

Have same problem in IE11.
const {keccak256, keccak256s} = __webpack_require__("../../../../web3/packages/web3-eth
Project from Angular 4, node v 6.10

[frozeman]

Should be solved in the next version, otherwise please reopen

I'm confused. Did frozeman's 9/15 commit fix this issue? Should it be working in version 0.20.2?
