Question

从OSGeo4W启动的命令窗口开始，我成功安装了与在Windows 7上运行的python 2.7兼容的fastkml python包。

当我从命令窗口运行python时，我可以从fastkml包中导入kml模块。

但是，如果我从同一个命令窗口启动IDLE用户界面并尝试从fastkml包导入kml模块，我会收到如下错误：

Python 2.7.10 (default, May 23 2015, 09:40:32) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
> from fastkml import kml

以下是用于启动OSgeo4W的bat文件中的代码，后者又启动了IDLE

@echo off
set OSGEO4W_ROOT=%~dp0
rem Convert double backslashes to single
set OSGEO4W_ROOT=%OSGEO4W_ROOT:\\=\%
echo. & echo OSGEO4W home is %OSGEO4W_ROOT% & echo.
set PATH=%OSGEO4W_ROOT%\bin;%PATH%
rem Add application-specific environment settings
for %%f in ("%OSGEO4W_ROOT%\etc\ini\*.bat") do call "%%f"
CALL C:\Python27\Lib\idlelib\idle.bat
@echo on
@if [%1]==[] (echo run o-help for a list of available commands & cmd.exe /k)    else (cmd /c "%*")

我怀疑，你安装了两个python 2.7。我可以从路径和启动画面中看到：

C：\ python27有2.7.10，您的批处理文件用它来运行IDLE。

C：\ OSGeo4W \ apps \ Python27必须有2.7.4，这可能是您直接运行的python，并且可以正确导入。

在两个shell中运行>>> import sys; sys.executable将验证或更正这些结论。如果它们是正确的，那么可能的解决方法是使用C:\python27替换批处理文件中的C:\OSGeo4W\apps\Python27，以便在运行的python上运行IDLE。当然，C:\OSGeo4W\apps\Python27\Lib可能不包含\idlelib。
