当使用'--watch'时,Sass 3.3.0'NoMethodError' - 错误

Question

刚在Mac和Windows上安装了全新的稳定Sass 3.3.0(Maptastic Maple).当使用-f --update sass:css它的工作正常.但是在使用时--watch我会得到一个NoMethodError错误.

没有--trace:

C:\RemoteProjects\sass-sourcemaps>sass --style expanded --sourcemap --watch sass:css
>>> Sass is watching for changes. Press Ctrl-C to stop.
NoMethodError:

使用--trace

C:\RemoteProjects\sass-sourcemaps>sass --style expanded --watch ./:../css --trace
>>> Sass is watching for changes. Press Ctrl-C to stop.

        from C:/Ruby200-x64/bin/sass:23:in `<main>'

有人有任何想法吗？我们真的需要这个--watch功能进行本地开发.

感谢Jose Gonzalez链接的https://github.com/nex3/sass/issues/1151页面.如该页面所述,修复方法是删除listenv2.7.0 gem并恢复为listenv2.4.1 gem.

在Mac上,使用下面的命令作为前缀 sudo

所以只需更新到Sass 3.3.0:

gem update sass

检查您是否有更新版本的listengem,运行:

gem list

如果你有listenv2.7.0和v2.4.1,那么你需要卸载更新的listensgem.然后它将使用v2.4.1.

gem uninstall listen --version '2.7.0'

这对我有用.Sass 3.3.0 --watch命令现在正常工作.
