Sass 如何用“重写只读文件”；罗盘编译“；指挥部？

我发现MS Visual Studio web项目文件夹来自TFS服务器，其中包含多个*.scss文件，并且已经生成了*.css（由Mindscape web Workbench Visual Studio插件生成）

发布之前，站点希望使用Compass重新生成*.css文件。
但是文件*.css文件包含在项目中并签入，所以它们被标记为只读文件属性

我的命令行：

C:\Ruby193\bin>compass compile
   --force
   --sass-dir 'd:\SDesign'
   --css-dir 'd:\SDesign' 
   --output-style compressed
   --no-line-comments
   --relative-assets
   --trace

结果如下：

overwrite Style.css

有没有办法不手动重置目标*.css文件中的只读属性？
也许是一些神奇的命令参数

提前谢谢。

这是我的临时解决方案。
如果你更懂路，请告诉我

@echo off
set ruby_bin=c:\Ruby193\bin
set project_path=d:\CDesign
set temp_path=%project_path%\temp

if exist "%temp_path%" rd "%temp_path%" /Q /S
mkdir "%temp_path%"

call %ruby_bin%\compass.bat compile --force --sass-dir '%project_path%' --css-dir '%temp_path%' --output-style compressed --no-line-comments --relative-assets

xcopy %temp_path%\*.* %project_path% /S /R /Y
rd "%temp_path%" /Q /S
