Appium1.9 之 Chromedriver安裝方式

1、在 appium 官網上下載安裝后，下載的是1.7.1的版本，安裝之后是1.9.1最新版本。

2、appium安裝之后，會發現涉及到 瀏覽器相關的業務時（我使用的是chrome)會提示 “No Chromedriver found that can automate Chrome '62.0.3202'”。

from appium import webdriver

desired_caps['platformName'] ='Android'        
desired_caps['platformVersion'] ='7.0'       
desired_caps['deviceName'] ='DIYTHYTCCQBIV47D'

driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)


print(driver.current_package)
print(driver.current_activity)


#輸出錯誤如下：

3、按照錯誤提示提供的 github 鏈接去查看如何安裝這個driver，發現使用 npm 命令進行安裝。

4、打開命令行窗口，輸入npm 提示命令無效，接下來就得要先安裝某個軟件才能支持這個命令，網上上查找一翻之后是要安裝 Node.js，之前老的appium版本(v1.4左右）是會自帶這個node.js的，新版本目前未發現。

5、前往 Node.js 官網下載跟系統匹配的版本進行安裝，安裝時一路點 Next 直到 Finish 即可。

6、重新打開命令窗口，輸入 npm -v 會提示出版本號，如果未顯示出版本號則可能是安裝出問題，請將上面步驟重新跑一遍。 

7、然后查找瀏覽器的版本號，找到對應的chrmoedriver 版本號，匹配關系如下：

The following is a list of Chromedriver versions and their corresponding minimum Chrome version that is automatable:

上述chromedriver版本匹配及下載鏈接為：點擊跳轉

8、在命令行窗口輸入 npm install appium --chromedriver_version="2.35" ，我的瀏覽器版本是 62.0.3202.84 對應匹配的 chromedriver為 2.35

9、待安裝完成即可
