按照此处http://docs.grafana.org/project/building_from_source/的说明，我能够构建 Grafana 并启动服务器侦听http://localhost:3000但 CSS 显然无法正常工作。我试图重新执行构建前端资产的构建命令，但我遇到了以下序列的错误：
npm install
npm install -g grunt-cli
grunt
不清楚这些命令应该从哪个目录执行。我假设 $GOPATH/src/github.com/grafana/grafana 但是当我执行第一个命令时，npm install我得到了一系列看起来像这样的错误：
npm WARN locking Error: EACCES, open '/Users/sam/.npm/_locks/glob-386d0e7784ce4d2e.lock'

我从这里https://nodejs.org/download/docs/latest/安装了 NodeJS ，我已经检查了 /usr/local/bin 的 npm 并且它存在，但我不确定在安装它时是否错过了配置步骤。
当我进入下一步执行时，npm install -g grunt-cli我得到一个错误块（类似于上一个），如下所示：
npm WARN locking Error: EACCES, open '/Users/sam/.npm/_locks/grunt-cli-58f484dab06f0a30.lock'

最后，当我执行时grunt，出现以下致命错误：
grunt-cli: The grunt command line interface. (v0.1.13)
Fatal error: Unable to find local grunt.
If you're seeing this message, either a Gruntfile wasn't found or grunt
hasn't been installed locally to your project. For more information about
installing and configuring grunt, please see the Getting Started guide:
http://gruntjs.com/getting-started
我还验证了我在项目目录中有 package.json 和 Gruntfile.js 文件。如果有帮助，以下是所有文件的列表：

当我使用./bin/grafana-server（来自 $GOPATH/src/github.com/grafana/grafana）启动服务器时，我得到了预期的输出，但随后导航到http://localhost:3000并添加了带有 404 错误的最后一行，如下所示：

以下是项目中包含的 Gruntfile.js 的内容（即我没有写）：
/* jshint node:true */
'use strict';
module.exports = function (grunt) {
var os = require('os');
var config = {
pkg: grunt.file.readJSON('package.json'),
baseDir: '.',
srcDir: 'public',
destDir: 'dist',
tempDir: 'tmp',
arch: os.arch(),
platform: process.platform.replace('win32', 'windows'),
};
if (process.platform.match(/^win/)) {
config.arch = process.env.hasOwnProperty('ProgramFiles(x86)') ? 'x64' : 'x86';
}
config.pkg.version = grunt.option('pkgVer') || config.pkg.version;
// load plugins
require('load-grunt-tasks')(grunt);
// load task definitions
grunt.loadTasks('tasks');
// Utility function to load plugin settings into config
function loadConfig(config,path) {
require('glob').sync('*', {cwd: path}).forEach(function(option) {
var key = option.replace(/\.js$/,'');
// If key already exists, extend it. It is your responsibility to avoid naming collisions
config[key] = config[key] || {};
grunt.util._.extend(config[key], require(path + option)(config,grunt));
});
// technically not required
return config;
}
// Merge that object with what with whatever we have here
loadConfig(config,'./tasks/options/');
// pass the config to grunt
grunt.initConfig(config);
};
此外，由于它被要求，这里是项目中所有 CSS 文件的列表（尽管我不确定这些是否是 UI 使用的 CSS 文件）：
10:23:03|~/Projects/go/src/github.com/grafana/grafana$ find . -iname "*.css"
./emails/assets/css/ink.css
./emails/assets/css/style.css
./public/vendor/angular/angular-csp.css
./public/vendor/angular-native-dragdrop/demo/css/styles.css
./public/vendor/angular-native-dragdrop/docs/css/styles.css
./public/vendor/css/font-awesome.min.css
./public/vendor/css/normalize.min.css
./public/vendor/css/spectrum.css
./public/vendor/css/timepicker.css
有人对如何使 CSS 正常工作有任何建议吗？我希望我遗漏了一些明显的东西，但我已经在这工作了几个小时，找不到任何有帮助的东西。谢谢！
