java - jruby Rails:Java::JavaLang::OutOfMemoryError:Java 堆空间

Question

我正在尝试编译我的 javascript 资源。我已经包含了plotly.js 文件，大小几乎为2MB。我还包含了 angualr2.dev.js 文件，该文件的大小也是 1MB。

每当我使用命令 rake asset:precompile RAILS_ENV=product 编译我的 Assets 时，我都会遇到以下错误。

我该如何解决这个问题？

Answer 1

尝试使用备用 ExecJS 运行时进行预编译(例如安装了 node)

...而不是gem 'therubyrhino'
