Question

我正在Windows环境中使用QGIS Pisa。我想升级OSGeo4W中存在的Python的scipy模块。为此我从OSGeo4W windows命令shell安装了pip。我在安装后关闭了命令shell并重新打开它。当我在OSFGeo4W windows命令shell中给出pip命令时，它指的是在系统级安装的pip模块，因此我收到错误。我不知道如何纠正这件事。这是我的错误堆栈跟踪：

    Traceback (most recent call last):
    File "C:\Program Files (x86)\QGIS Pisa\apps\Python27\lib\runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name)

    File "C:\Program Files (x86)\QGIS Pisa\apps\Python27\lib\site-packages\pip\_vendor\packaging\specifiers.py", line 275, in <module>

    File "C:\Program Files (x86)\QGIS Pisa\apps\Python27\lib\re.py", line 242, in _compile raise error, v # invalid expression
    sre_constants.error: nothing to repeat

正如您在stacktrace上看到的，从顶部开始的第3行，代码指的是安装在系统级别的python的pip模块，而不是安装在QGIS Pisa中的pip模块。我怎样才能正确地运行它？

QGIS python模块正在干扰系统级安装的另一个python模块
