./Allwmake运行出错

Tingswy

环境变量是
source /opt/OpenFOAM-2.2.1/etc/bashrc
安装目录就是/opt/OpenFOAM-2.2.1

在OpenFOAM下面运行./Allwmake 提示权限不够 无法创建文件

因此我就sudo ./Allwmake
结果提示

tings@linux-ohyj:/opt/OpenFOAM-2.2.1> sudo ./Allwmake
./Allwmake:行4: wmakeCheckPwd: 未找到命令
Error: Current directory is not $WM_PROJECT_DIR
    The environment variables are inconsistent with the installation.
    Check the OpenFOAM entries in your dot-files and source them.

之后我就进入$WM_PROJECT_DIR
tings@linux-ohyj:/opt/OpenFOAM-2.2.1> cd $WM_PROJECT_DIR
tings@linux-ohyj:/opt/OpenFOAM-2.2.1>


就这样死循环了 这是为什么啊？
求Foamer高手帮忙解答！！！
