我正在尝试安装

我一直得到

npm WARN deprecated npmconf@2.0.9: this package has been reintegrated into npm and is now out of date with respect to npm
npm WARN grunt-penthouse@0.3.0 requires a peer of grunt@~0.4.2 but none was installed.

---

我试过了

sudo npm update -g npm

/usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js
/usr/local/lib
└── npm@3.8.7 

sudo npm install -g grunt-cli

/usr/local/bin/grunt -> /usr/local/lib/node_modules/grunt-cli/bin/grunt
/usr/local/lib
└── grunt-cli@1.2.0

sudo npm install grunt-critical-css --save-dev

npm WARN deprecated npmconf@2.0.9: this package has been reintegrated into npm and is now out of date with respect to npm
npm WARN grunt-penthouse@0.3.0 requires a peer of grunt@~0.4.2 but none was installed.

我在这里做错了什么？有人可以填写我遗漏的吗？

Gruntfile.js

criticalcss: {
    custom: {
        options: {
            url: "http://localhost:8888",
            width: 1200,
            height: 900,
            outputfile: "public/dist/wedding/css/critical.css",
            filename: "public/dist/wedding/css/all.css",
            buffer: 800*1024,
            ignoreConsole: false
        }
    }
},

加载它

grunt.loadNpmTasks('grunt-critical-css');

叫它

 grunt.registerTask('default', [

    'clean:dist',
    'concat',
    'uglify',
    'cssmin',
    // 'htmlmin',
    'compress',
    'criticalcss'

]);

结果

咕哝

Warning: Task "criticalcss" not found. Use --force to continue.
Aborted due to warnings.

咕噜 --force

Warning: Task "criticalcss" not found. Used --force, continuing.
Done, but with warnings.

去检查文件

Nothing generated 

Answer 1

这些是警告消息，通常即使您有这些消息，您的npm install 也会成功进行。

这些消息是根据您安装的软件包的所有package.json 依赖注册表以及您正在安装的软件包的所有层次依赖关系生成的。

例如，您正在安装的软件包grunt-critical-css 具有此package.json https://github.com/filamentgroup/grunt-criticalcss/blob/master/package.json 例如具有此依赖关系grunt-cli 具有此package.json https://github.com/gruntjs/grunt-cli/blob/master/package.json ...等等。

在您的情况下，其中一个依赖包，即 npmconf@2.0.9 已被贬值。

这个插件需要 Grunt ~0.4.2

看起来您没有安装正确的 Grunt 版本。 试试这个：

npm update -g npm

或

sudo npm update -g npm

然后：

npm install -g grunt-cli
