Python 3.5.1无法下载Robot Framework库

Question

我是Python的新手，我正在尝试用Robot Framework自动化测试。当我尝试通过pip下载这个库时，我遇到了一些问题。我用的是Python 3.5.1，Robot Framework 3.0，PyCharm 2016.1(64)

命令pip install robotframework-selenium2library：Collecting robotframework-selenium2library Using cached robotframework-selenium2library-1.7.4.tar.gz Complete output from command python setup.py egg_info: Downloading http://pypi.python.org/packages/source/d/distribute/distribute-0.6.14.tar.gz Extracting in C:\Users\Radek\AppData\Local\Temp\tmpooendh2g Traceback (most recent call last): File "c:\users\radek\appdata\local\programs\python\python35\lib\site-packages\ez_setup.py", line 143, in use_setuptools raise ImportError ImportError的输出在处理上述异常的过程中，发生了另一个异常：

    self.chown(tarinfo, dirpath)

----------------------------------------

C:\Users\Radek\AppData\Local\Temp\pip-build-gh4jw21a\robotframework-selenium2library\中的命令"python setup.py egg_info“失败，错误代码为%1

安装工具是最新的，ez_setup也是最新的

C:\Users\Radek>pip install --upgrade setuptools Requirement already up-to-date: setuptools in c:\users\radek\appdata\local\programs\python\python35\lib\site-packages C:\Users\Radek>pip install ez_setup Requirement already satisfied (use --upgrade to upgrade): ez-setup in c:\users\radek\appdata\local\programs\python\python35\lib\site-packages

Selenium2Library与Python3.x不兼容。

我们有一个拉取请求(github.com/robotframework/Selenium2Library/pull/564)，要求Selenium2Library与所有Python版本兼容，但它不在官方版本中，它已经在Python2.6、2.7和3.4上进行了测试。

如果你想安装，你可以试试github.com/HelioGuilherme66/robotframework-selenium2library/releases/tag/v1.8.0b1，例如: pip install -U --pre https://github.com/HelioGuilherme66/robotframework-selenium2library/archive/v1.8.0b1.zip
