我在Windows 7上安装了Python 2.7中的SCons 2.2.0。当从cmd运行“scons”时,我收到错误消息“scons无法识别,内部或外部命令”我该如何解决这个问题?在Windows 7 cmd上运行Scons 2.2.0


问题是scons-2.2.0-setup.exe没有在系统中设置路径。 scons.bat和scons-2.2.0.bat都可以在“C:/ Python27/Scripts”文件夹中找到。将其设置为路径确实可以解决问题。现在尝试编译时会出现一个新问题,一个带有消息“cl”的简单C++文件不会被识别为内部或外部命令。 (Windows 7 64位)。请任何想法可能会有所帮助。

你使用SCons windows installer安装它?它应该为你设置一切。

按照SCons installation instructions,使用SCons应该在这里安装:

  • C:\ Python25 \ Scripts中
  • C:\ Python25 \ scons的

在你的情况下,替换c:\Python25你的pythong 2.7安装位置。

此外,请确保SCons python脚本在您的路径。您可能必须重新启动cmd才能使路径的更改生效。

从该网页,我得到scons的scons的-2.2.0-SETUP.EXE for Windows和它从来没有设置路径为我和我无法找到特定的scons可执行文件的路径! – Amani 2013-02-16 20:12:16

链接不起作用(再)。这是通用下载页面:http://www.scons.org/download.php – Geier 2014-05-01 09:04:06

要使用CL,您需要使用Visual Studio命令行,然后从那里运行scons,在Python安装中运行它的.bat文件和脚本文件夹。把脚本放在你的路径上应该可以解决它,因为我最近自己做了这个。

我安装了2个最新版本(3.0.0和3.0.1)。

同样的问题,也许是因为

  1. Windows安装程序正在寻找的安装Python的C:/ Program Files文件...它只能发现Python 3.x都有 (这是不兼容的)

  2. setup.py有一个小问题。

无论如何,我带来了以下解决方案。

  1. python setup.py install
  2. 转到安装到你的Python安装目录
  3. 在子文件夹把下面的文件,无论(或两者)脚本

    • scons.bat如果运行scons的cmd
    • scons如果从MSYS运行scons的Cygwin的

我已经把这些2个脚本的代码如下(在.bat是将源代码的一部分,.sh已经从它的启发)。
