Eclipse Liferay 6.2 Ant构建-升级SCSS编译器

我目前正在开发liferay主题，但在编译其中一个SCSS文件时，出现以下错误：

我使用的是Liferay 6.2 EE GA1，我所读到的错误可能通过升级SCSS编译器（ruby gem）来修复。然而，我甚至不知道如何处理这个问题。它使用的是

ant

builder（build.xml）

---

如果我可以修复上面的错误，或者升级编译器（或者两者都升级？），那就太好了

如果要手动升级SASS版本，可以重新设置

scripting.jruby.load.paths

属性。请看一看。因此，您使用的不是classpath或

java.io.tmpdir

，而是一个不同的文件夹。然而，我并没有测试这个，也许其他一些东西会在这次升级中失败（您还需要一个关于CI构建的概念）

我成功地将Liferay 6.2升级到bootstrap 4：

您需要转到tomcat/webapps/ROOT/WEB-INF/lib并删除ruby gems.jar

下载com.liferay.ruby.gems-1.0.1.jar（在线搜索），并将其放在上面的lib文件夹中

修改您的portal-ext.properties并添加以下内容：

清理tomcat的工作和临时目录，然后重新启动Liferay

---

我还稍微改变了我的主题。将所有的aui.css、main.css（和导入）文件更改为scss文件（因为它们不是真正的css），并使用webpack 4编译它们（比Ruby快得多）。

我不知道，但听起来好像Liferay嵌入式scss编译器无法解析bootstrap 3源代码。最好看看这个项目：我不知道，但听起来好像Liferay嵌入式SCSS编译器无法解析bootstrap 3源代码。最好看看这个项目：
