使用 npm 错误安装 phantomjs

Question

I'm doing a unit testing for my javascript codes. I prefer to use a headless browser for easier running. It goes well when I installed some dependencies but when I install phantomjs, it has an error.

C:\\Phantomjs>npm install -g phantomjs npm WARN deprecated phantomjs@2.1.7: Package renamed to phantomjs-prebuilt. Plea se update 'phantomjs' package references to 'phantomjs-prebuilt' npm WARN deprecated node-uuid@1.4.8: Use uuid module instead npm WARN deprecated tough-cookie@2.2.2: ReDoS vulnerability parsing Set-Cookie h ttps://nodesecurity.io/advisories/130 C:\\Users.ra\\AppData\\Roaming\\npm\\phantomjs -> C:\\Users.ra\\AppDa ta\\Roaming\\npm\\node_modules\\phantomjs\\bin\\phantomjs

phantomjs@2.1.7 install C:\\Users.ra\\AppData\\Roaming\\npm\\node_modules\\ phantomjs node install.js

What should I do?

Answer 1

The simplest installation method is

1. Install NodeJS
2. Using Node's package manager install phantomjs: npm -g install phantomjs-prebuilt

After installation, you may use phantom as simple as:

driver = webdriver.PhantomJS() # or add to your PATH
driver.set_window_size(1024, 768) # optional
driver.get('https://google.com/')
driver.save_screenshot('screen.png') # save a screenshot to disk
sbtn = driver.find_element_by_css_selector('button.gbqfba')
sbtn.click()

If your system path environment variable isn't set correctly, you'll need to specify the exact path as an argument to webdriver.PhantomJS() . Replace this:

driver = webdriver.PhantomJS() # or add to your PATH

... with the following:

driver = webdriver.PhantomJS(executable_path='/usr/local/lib/node_modules/phantomjs/lib/phantom/bin/phantomjs')

Answer 2

Try run npm install phantomjs-prebuilt

phantomjs name changed to phantomjs-prebuilt on Pre-2.0 version release.
