在 Windows 7 上使用 Python 安装 Robot Framework 时出现错误

Question

我已成功安装“python-3.3.0.msi”并将 PATH 设置为“C:\Python33;” 在Windows 7上。之后我尝试使用“robotframework-2.7.7.win32.exe”（双击.exe文件）安装Robot Framework。在安装的最后一步我发现了以下错误：

File "<string>", line 35
    except Exception, err:
                    ^
SyntaxError: invalid syntax

我单击“完成”按钮 --> 安装向导消失了。我将路径设置为“C:\Python33\Scripts”。然后我在命令提示符下使用命令“pybot --version”检查版本。显示以下错误：

Traceback (most recent call last):
  File "C:\Python33\lib\runpy.py", line 140, in _run_module_as_main
    mod_name, loader, code, fname = _get_module_details(mod_name)

    except EnvironmentError, err:
                           ^

我该如何解决上述错误？

Robot Framework 尚不支持 Python 3。您应该尝试使用 Python 2.7。（Python 3 改变了语言语法中的很多内容，包括此回溯中显示的用于捕获异常的语法）。因此，请按照以下安装步骤操作：

1. 安装Python2.7.3
2. 安装robotframework2.7.7
3. 将 PATH 设置为“C:\Python27\;C:\Python27\Scripts\”
4. 在命令提示符下使用命令“pybot --version”验证安装。如果一切正常，
   将显示以下消息：“Robot Framework 2.7.7 (Python 2.7.3 on win32)”
