我正在尝试通过在 Windows 7 上的 Cygwin 上键入以下命令来使用 bake 下载、构建和测试 NS-3：
$ cd
$ mkdir workspace
$ cd workspace
$ hg clone http://code.nsnam.org/bake
然后我将目录更改为烘焙目录并输入：
$ export BAKE_HOME=`pwd`
$ export PATH=$PATH:$BAKE_HOME:$BAKE_HOME/build/bin
$ export PYTHONPATH=$PYTHONPATH:$BAKE_HOME:$BAKE_HOME/build/lib
然后 ：
./bake.py configure -e ns-3.25
我没有在屏幕上显示任何内容，然后输入：
./bake.py check
我在屏幕上显示以下内容：

然后我在命令提示符上输入：
$ ./bake.py download
