python pip安装selenium时报错， ..has requirement websocket-client==0.48.0, but you'll have websocket -client 0.57.0 which is incoopatibale.

默认打开cmd，无法执行pip install selenium，报错：‘pip‘ 不是内部或外部命令，也不是可运行的程序或批处理文件。

所以cd到python script的根目录，cd C:UsersAdministratorAppDataLocalProgramsPythonPython37-32Scripts

然后在运行pip install selenium

报错：waston-developer-cloud 2.6.0 has requirement websocket-client==0.48.0, but you'll have websocket -client 0.57.0 which is incoopatibale.

 只能手动安装了。

chromedriver的安装这里略。

然后，python测试一下chromedriver的安装。

import time
from selenium import webdriver

driver = webdriver.Chrome('C:/Program Files (x86)/Google/Chrome/Application/chromedriver') # Optional argument, if not specified will search path.
driver.get('http://www.google.com/');
time.sleep(5) # Let the user actually see something!

driver.maximize_window()
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()

　　测试成功。
