标签: uglifycss

对于我的prod环境,我想使用如下配置的UglifyCSS过滤器(config_prod.yml):

assetic:
    filters:
        uglifycss:
            node: /usr/bin/env node
            bin: /usr/local/bin/uglifycss
            apply_to: "\.css$"

但无论何时我跑

php app/console assetic:dump --env=prod --no-debug

我收到此错误消息:

[Assetic\Exception\FilterException]

很明显,Assetic正在寻找uglifycss,/usr/bin尽管我将它配置为使用不同的路径,/usr/local/bin.有谁知道这里发生了什么？

我已经UglifyCSS使用命令全局安装：

npm install -g uglifycss

如何获取已安装的当前版本UglifyCSS？

聚苯乙烯

UglifyJS我用命令检查的版本：

uglifyjs -V

但是当我尝试类似的命令时UglifyCSS：

uglifycss -V

我有一个错误：

unable to process "-V" with Error: ENOENT, no such file or directory '-V'

当我尝试时出现同样的-v错误--version
