Liferay 6.2 Ant构建-升级SCSS编译器

Question

我目前正在开发一个救生筏主题，但是在编译一个SCSS文件时，我会得到以下错误：

违规文件(aui.css)：

$FontAwesomePath: "aui/font-awesome-5/font" !default;

//@import "aui/alloy-font-awesome/scss/variables";
//@import "aui/alloy-font-awesome/scss/mixins-alloy";
//@import "aui/alloy-font-awesome/scss/path-alloy";

.aui {
    @import "aui_variables";

    $iconSpritePath: '../images/aui/glyphicons-halflings.png' !default;
    $iconWhiteSpritePath: '../images/aui/glyphicons-halflings-white.png' !default;

    //@import "aui/bootstrap"; // Remove >> Bootstrap 2.3.2
    @import "aui/variables-alloy";
    @import "aui/variables";
    @import "aui/bs4/bootstrap"; // Add >> Bootstrap 3.5
}

我使用的是Liferay6.2EE GA1，从我所读到的内容来看，这个错误可以通过升级SCSS编译器(ruby )来修复。不过，我根本不知道该怎么处理。它正在使用ant生成器(build.xml)。

如果我可以修复上面的错误，或者升级编译器(或者两者都可以？)那就太好了！

Answer 1

如果要手动升级SASS版本，可以重新设置scripting.jruby.load.paths属性.请看一下6.2门户属性。因此，您不是使用类路径或java.io.tmpdir，而是使用不同的文件夹。然而，我没有测试这一点，也许这次升级还会有其他的问题(你也需要一个关于CI构建的概念)。

Answer 2

我成功地将Liferay 6.2升级到引导4：

1. 您需要转到tomcat/webapp/ROOT/WEB/lib，并删除ruby-gis.jar
2. 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
3. 修改门户-ext.properties并添加以下内容：

#jruby fix
scripting.jruby.load.paths=\
classpath:/META-INF/jruby.home/lib/ruby/site_ruby/1.8,\
classpath:/META-INF/jruby.home/lib/ruby/site_ruby/shared,\
classpath:/gems/chunky_png-1.3.5/lib,\
classpath:/gems/compass-1.0.1/lib,\
classpath:/gems/compass-core-1.0.3/lib,\
classpath:/gems/multi_json-1.11.3/lib,\
classpath:/gems/fssm-0.2.9/lib,\
classpath:/gems/sass-3.4.22/lib,\
${java.io.tmpdir}/liferay/ruby/gems/chunky_png-1.3.5/lib,\
${java.io.tmpdir}/liferay/ruby/gems/compass-1.0.1/lib,\
${java.io.tmpdir}/liferay/ruby/gems/fssm-0.2.9/lib,\
${java.io.tmpdir}/liferay/ruby/gems/sass-3.4.22/lib

1. 清理猫的工作和温度，然后重新启动Liferay

此外，我还将我的主题bit..changed --所有的aui.css、main.css (和导入)文件--更改为scss文件(因为它们实际上不是css文件)，并使用webpack 4编译它们(比Ruby快得多)。
