Python版本错误识别

标签： python python-3.x pip

我已经开始使用pyqtdeploy来使用pyqt和制作跨平台应用程序。不幸的是，当我真正尝试启动它时，我收到错误：

  

启动程序中的致命错误：无法使用C：\ Python34 \ python.exe创建进程C：\ Python34 \ pyqtdeploy

我看了this earlier question，但python3 -m pip install pyqtdeploy --upgrade也给了我类似的错误。

使用十六进制编辑器似乎相当危险和极端？对此有另一种解释/解决方案吗？我的python34路径中没有空格，所以这不是问题所在。可能是我的Python27安装吗？

编辑：

我试过了py -m pip install pyqtdeploy --upgrade（感谢@Saurabh Randhawa），但这没效果。命令失败，并显示以下内容：

我知道我正在运行Python 3.4.2。可能是什么导致了这个？它说版本错了，但显然不是。

EDIT2 ：好的，这真的很奇怪，我尝试再次运行命令（没有尝试任何解决方案！），并且它有效。工作代码：python3 -m pip install pyqtdeploy --upgrade。如果不改变任何事情，为什么会改变呢？

在编辑时，我在64位窗口上运行32位Python（两个版本）。

日志中的这一行：

C:\Python27\lib\site-packages\pip\__main__.py

证明除了3.4之外你还有一个Python2.7安装......这是pip使用的那个！

根据Python 3.4手册的建议，您可以尝试使用明确的py -3：

py -3   -m pip install pyqtdeploy --upgrade  # default Python 3
py -3.4 -m pip install pyqtdeploy --upgrade  # specifically Python 3.4

py的神奇之处在于，当您安装了多个版本时（例如您的情况），可以找到并启动以更正Python版本。

  • 以管理员身份启动命令提示符

    1. 单击“开始”，单击“所有程序”，然后单击“附件”。
    2. 右键单击“命令提示符”，然后单击“以管理员身份运行”。
    3. 如果出现“用户帐户控制”对话框，请确认其显示的操作是您所需的操作，然后单击“继续”。

  • 输入py -m pip install pyqtdeploy --upgrade

答案 2 :(得分：1)

Python安装（至少在windows下）设置PYTHONPATH环境变量，例如：

C:\Users\vyktor>SET PYTHONPATH
PYTHONPATH=C:\Python32\Lib;C:\Python32\DLLs;C:\Python32\Lib\lib-tk

所以你可能将PYTHONPATH设置为27版......

尝试手动设置值：

C:\Users\vyktor>SET PYTHONPATH=C:\Python34\Lib

C:\Users\vytkor>SET PYTHONPATH
PYTHONPATH=C:\Python34\Lib

重新执行脚本，它应该可以正常工作。
