針對robotframework-selenium2library的Python pip沖突

Question

我嘗試安裝robotframework-selenium2library但是采取了pkg_resources.VersionConflict錯誤：

Downloading/unpacking robotframework-selenium2library
  Downloading robotframework-selenium2library-1.8.0.tar.gz (118kB): 118kB downloaded
  Running setup.py (path:/tmp/pip_build_root/robotframework-selenium2library/setup.py) egg_info for package robotframework-selenium2library
    Traceback (most recent call last):
      File "<string>", line 17, in <module>
      File "/tmp/pip_build_root/robotframework-selenium2library/setup.py", line 7, in <module>
        from ez_setup import use_setuptools
      File "/tmp/pip_build_root/robotframework-selenium2library/src/ez_setup.py", line 106
        except pkg_resources.VersionConflict, e:

    SyntaxError: invalid syntax
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

    except pkg_resources.VersionConflict, e:

                                        ^

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/robotframework-selenium2library
Storing debug log for failure in /root/.pip/pip.log

沒有安裝太多的軟件包：

pip list
> apparmor (2.9.4)
> LibAppArmor (2.9.4)
> pip (1.5.6)
> pygobject (3.14.0)
> robotframework (3.0.2)
> robotframework-databaselibrary (1.0.1)
> selenium (3.4.3)
> setuptools (3.6)

python --version
> Python 2.7.12

有人知道如何解決這個問題嗎？

Answer 1

PyPI（1.8.0）上的robotframework-selenium2library的版本相當陳舊，當你嘗試用Python 3安裝時，它只支持Python 2.要么使用Python 2.7，要么從GitHub獲取框架的新代碼。

Answer 2

我查看了github Seleniumlibrary ，你可以使用：

pip install --pre --upgrade robotframework-seleniumlibrary
