python開發過程中遇到的問題記錄一下方便查找(持續更新):
**
1.Cannot uninstall ‘urllib3’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
問題解析：舊版本依賴多，不能清晰的刪除，此時應該忽略舊版本升級，即如下
解決辦法：sudo pip install urllib3 --ignore-installed urllib3
2.FileNotFoundError: [Errno 2] No such file or directory: ‘geckodriver’
問題解析：缺少火狐瀏覽器驅動文件geckodriver
解決辦法: 在如下網址找對應自己系統的驅動:https://github.com/mozilla/geckodriver/releases/
3.selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities
問題解析：瀏覽器版本和驅動不對應
解決辦法: 尋找瀏覽器版本匹配的驅動文件，或者更新瀏覽器
4.TypeError: urlopen() got multiple values for keyword argument ‘body’
問題解析：urllib3版本太低
解決辦法: sudo pip install urllib3或sudo pip3 install urllib3
5.See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnin
解決辦法:
import urllib3
urllib3.disable_warnings()
6.pip安裝到python2路徑下(python2和python3共存,默認python3)
解決方法：python2 -m pip install xxx
