我试图用pythonwebassets简单地编译bootstrap4,但是没有成功。现在,我只想在bootstrap/scss目录中执行此操作,这样路径问题就不那么重要了。在这个目录中,我添加了一个main.scss
文件,其中有一行:
@import "bootstrap.scss";
我有一个名为test_scss.py
的脚本,如下所示:
当我运行这个命令时,我会得到如下的错误跟踪:

如果我按照说明操作并设置环境变量SASS_PATH=.
,这将消除错误消息的这一部分,但仍然会得到错误消息

我还不太了解SCSS语法,但我敢打赌这是我做错了什么,而不是引导SCSS中的错误。如果你能想到我做错了什么,我将不胜感激。在
事实上这是引导端的一个问题。参见https://github.com/sass/sass/issues/2383,特别是引用:
总之,我只需要更新到Ruby Sass的最新版本(显然webassets模块依赖于它),然后就修复了它。在
