Hi,
I can't get selenium to import inside the node terminal while working in Workspaces.
$ npm install selenium-webdriver
$ npm install chromdriver
> const selenium = require("selenium-webdriver");
/home/treehouse/workspace/node_modules/selenium-webdriver/lib/http.js:454
async execute(command) {
^^^^^^^
SyntaxError: Unexpected identifier
I tried googling the error, but nothing really came up. Any help would be appreciated!

Treehouse TeacherHey David!
Check the teachers notes on this video. It has the correct command.
Thanks!

> const selenium = require("selenium-webdriver@3");
Error: Cannot find module 'selenium-webdriver@3'
at (...etc.)
> const selenium = require("selenium-webdriver");
TypeError: Identifier 'selenium' has already been declared
at (...etc.)
I'm not getting: undefined
Craig Dennis
Treehouse TeacherOnly change the npm install ...rest of the code is the same. The error there is from using const after already using one.
Again just the npm install changes, not the code.
Sorry for the confusion!
David Jackson
1,982 PointsWell now I'm getting a TypeError: Identifier 'driver' has already been declared for: const driver = new selenium.Builder().forBrowser("chrome").build(); But yet, when I go ahead with the tutorial, I see: ReferenceError: driver is not defined
Craig Dennis
Treehouse TeacherHi David,
const makes it so you can no longer define a variable with that name. So you declared driver with const, and then tried to declare it again. Doesn't have anything to do with versioning at this point.
Give it another go! Hope that helps!

22,989 PointsI thought about this being the issue but I'm not allowed to update node or npm through
yum. I don't have sudoers access on workspaces. I could try installing locally from source.Node is v6.11.1, npm is 3.10.10. He says at the start of the course that version 6 should be okay but maybe not lol.

56,414 PointsI see Selenium bumped up to 4.0.0.alpha.1 on npm. Woot, breaking changes!
Node needs to be version 8/9 to use async/await. If Node isn't upgradable, I'd suggest specifying the prior version for selenium-driver (3.6.0 for node) by the looks of it in package.json on re-install.

Treehouse TeacherYes thanks, please use the older version of selenium. Will work on getting the instructions in there. Thanks for the ping Seth Kroger !
