SyntaxError: Use of const in strict mode?
提问by Shubham Batra
I am trying to login on facebook.com with selenium-webdriver.
我正在尝试使用 selenium-webdriver 登录 facebook.com。
var webdriver = require('selenium-webdriver'),
By = require('selenium-webdriver').By,
until = require('selenium-webdriver').until;
var driver = new webdriver.Builder()
.forBrowser('firefox')
.build();
driver.get('https://www.facebook.com/login');
driver.findElement(By.id('email')).sendKeys('****');
driver.findElement(By.id('pass')).sendKeys('*****');
driver.findElement(By.id('loginbutton')).click();
driver.findElement(By.linkText('Settings')).then(function(element) {
console.log('Yes, found the element');
}, function(error) {
console.log('The element was not found, as expected');
});
driver.quit();
It is giving error:

Updating nodejssolved the issue:
更新nodejs解决了这个问题：
npm cache clean -f
sudo npm install -g n
sudo n stable
node --version
node app.js
You have to run the second and third command as root/administrator.
您必须以 root/管理员身份运行第二个和第三个命令。

n stablewouldn't do the trick for me. On the other hand,
n stable不会为我做的伎俩。另一方面，
nvm install stable
That actually got me to last nodejs version. Apparently n stablewon't get pass v0.12.14for me. I really don't know why.
这实际上让我到了最后一个 nodejs 版本。显然n stable不会让v0.12.14我通过。我真的不知道为什么。
Note: nvmis Node Version Manager, you can install it from its github page. Thanks @isaiah for noting that nvmis not a known command.
注意：nvm是 Node 版本管理器，你可以从它的 github 页面安装它。感谢@isaiah 注意到这nvm不是一个已知的命令。
