问题：在本地运行 Ruby-China，一直不停地报如下错误

diguage — Wed, 12 Aug 2015 17:07:29 +0800

最近看完了《Ruby 编程语言》，感觉有点太高屋建瓴，理解的不是很好。接着看了半本《The Well-Grounded Rubyist》，这本由浅入深，感觉非常不错，强推！然后又看完了《Ruby on Rails Tutorial》，也跟着代码敲了一遍，感觉很不错，看来学 Rails 之前还是看看 Ruby 理解地会更透彻。

再然后“野心勃勃”，想看看 RubyChina 的源代码。就在本地搭建起来。把环境依赖解决掉之后就顺利运行了。跑起来妥妥的。但是，观察日志，似乎一直在不停地刷日志。看了看，没发现什么问题，请帮忙看一下。

换了 Unicorn 后，又报错了。

日志如下：

如何选择 JavaScript 模板？

diguage — Fri, 23 Jan 2015 11:43:29 +0800

背景介绍

最近做一个项目，后台查询页面需要用 Ajax 请求，然后再展示出来。现在展示时，我直接用 JavaScript 拼接带标签的字符串来完成的。

随着对项目美观以及可用性要求的提高，字符串拼接方式越来越麻烦。而且，这种方式太 Low，木有美感！

就在昨天晚上，突然先到了 JavaScript 模板。我觉得这个东西能解决我的问题。然后，查了查资料，妥妥的…

背景介绍到此为止。

可选项目

上网一次，我了个擦，有如此多的可选项目。列表如下：

BaiduTemplate--百度出品。
artTemplate--腾讯出品。
Juicer--淘宝出品。
doT
jquery-tmpl
Handlebars.js
easyTemplate
Underscore.js
mustache.js
kissy

还有很多，这里就不一一列举了。

最后一击

看到这么多可选项，心里就一句话： ** 我了个擦，这么多，怎么选啊？**

我需要的功能：支持循环，这个是最基本的；支持子模板；最好能支持自定义选择函数（比如，我要选列表中最大的。）这个场景，怎么选？

想听听大家都选了哪个模板？以及选择原因。

网站访问速度很慢，如何检查并定位哪里是瓶颈？[问题作废]

diguage — Fri, 26 Sep 2014 18:01:20 +0800

昨晚和今天又测试，访问速度刚刚的。所以，这个问题作废。至于监控相关内容，我也在学习，以后另外发帖补充。谢谢！

为了加快访问速度，同时也为了能使用更多的国内服务，我把我的“‘地瓜哥’博客网”搬到了阿里云上。

备案今天审核完成。然后就把网站给搭起来了。

But，访问速度超慢。测试站点：地瓜哥测试站点。还不如我原来在美国的虚拟主机上快。

请问：如何检测并定位一个网站的速度瓶颈？监控这块一直比较薄弱，希望大家给指条路！

补充：

还是上面的测试站点，中午访问巨慢。刚刚试了一下，速度还可以。 莫非阿里云表现不稳定，故意特马耍我？

如何使用 XCode 查看 Redis 的源代码？

diguage — Thu, 18 Sep 2014 21:27:14 +0800

最近买了本Redis 设计与实现 (豆瓣)，想好好看一下 Redis 的实现，学习一下 Redis 的使用。

看到有人使用 XCode 查看 Node.js 等的源代码，在 xcode 中编译和调试 webkit, V8 和 Nodejs，我在想 能不能使用 XCode 看 Redis 的源代码？这样，就可以很方便的看 Redis 的代码，书应该也可以看的更透。但是，因为几乎没有用过 XCode，不知如何下手。

求指点：如何使用XCode查看Redis的源代码？

我在 StackOverflow 上发布了，这个问题，How to import redis's source to XCode? - Stack Overflow，可以去 StackOverflow 上回答，一起打怪升级，挣分学东西！哈哈

Linode 的 $10/mo 的 VPS 在怎么样？

diguage — Fri, 27 Jun 2014 09:39:28 +0800

Linode 最近推出的每月 10 美刀的底气套餐。从价格上来看，确实很接地气，让我有点心动。想入手一个？

不过，不知道 它的速度（尤其是在国内的访问速度）、稳定性怎么样？有哪位童鞋用过？能分享一下经验不？

以前看别人分享说，貌似东京国内访问最快，默认就以东京节点来说，如果有在国内访问更快的，也请告知一下。

阿里云与 Linode，哪个更靠谱？

diguage — Tue, 13 May 2014 08:23:40 +0800

由于目前个人博客（“地瓜哥”博客网）感觉 速度太慢，虚拟主机马上到期。准备换个地方托管。目前考虑的是 阿里云主机 和 Linode。

阿里云主机

速度应该是没问题
可以帮忙备案（这个不算是优点，不过原来公司办过备案，据说这个很简单）， 更主要是可以申请百度联盟。

Linode

看了看Startup News就是 Linode，速度还可以。
不用备案
还是担心速度！

孰优孰劣，难下选择。麻烦大家给提点建议吧。

有哪些关于闭包的经典用法？

diguage — Mon, 10 Mar 2014 14:39:46 +0800

在知乎提了个问题：有哪些关于闭包的经典用法？。无人回答，发到这里，大家一起来讨论讨论！

看 JavaScript 等方面的书，在讲解闭包时，经常提到“如果用好闭包，能多么多么方便，多么多么牛逼”。但是，我自己在写代码的时候，总是找不到这种“牛逼的赶脚”。（也许我水平有限，还没吃透。呵呵）

请问，有哪些关于闭包的经典用法？

请结合 JavaScript代码来说明。无码无真相！

使用 Mina 发布，报 production.log 权限不正确，求解答？

我的尝试

我使用chmod 666 /home/dgg/newp/tmp/ -R赋予相应的权限，但是还是报这个错误。在 StackOverflow 上查了一下，一些解答的目录貌似固定目录。对于我的这种情况不适用。

安装 bcrypt-ruby 总报错，求指点

diguage — Mon, 03 Mar 2014 19:02:45 +0800

在 Win7 上通过 vagrant 连接到 Ubuntu 12.04 64 位系统上，搭建 Rails 开发环境。其中依赖bcrypt-ruby，安装时报错，然后就使用如下命令再次安装：

gem install bcrypt-ruby -v '3.0.1' --no-rdoc --no-ri

结果，报错如下：

Building native extensions.  This could take a while...
ERROR:  Error installing bcrypt-ruby:
    ERROR: Failed to build gem native extension.

    /home/vagrant/.rvm/rubies/ruby-2.0.0-p353/bin/ruby extconf.rb

/extensions/x86_64-linux/2.0.0/bcrypt-ruby-3.0.1/gem_make.outdding

上网查了，StackOverflow 上有人需要安装g++、gcc、libssl-dev等，安装后这些依赖后，重试，还是报上面那个错误。然后，我把所有以libcrypt-开头的包都装上，继续安装gem install bcrypt-ruby -v '3.0.1' --no-rdoc --no-ri，但是还是报错。倒腾了一个多小时了，还是不行。跪求指点！

在 Rails 3.2.17 的项目中，如何将 Devise 从 2.2.4 升级到 3.2.3？

diguage — Sun, 02 Mar 2014 17:27:28 +0800

前两天在坛子里发帖Devise2 与 Devise3 有啥区别？。今天又看了看，感觉是自己没有表达清楚。现在，重新组织一下语言，重提一下问题。

目前在玩 Rabel，将 Devise 从2.2.4升级到3.2.3后， 登录正常工作，但是注册却提示“用户名、邮箱、密码不能为空字符串”。但是，这几个字段肯定填写啊，日志如下：

   (0.4ms)  SELECT COUNT(*) FROM `advertisements` WHERE (start_date <= '2014-03-02' AND expire_date >= '2014-03-02')

请问：在Rails 3.2.17的项目中，如何将Devise从2.2.4升级到3.2.3?

附录：运行环境

Rails 3.2.17
Devise 2.2.4 -> 3.2.3
simple_form 2.0.4

更多 Gem 相关信息，请看原来的帖子：Devise2 与 Devise3 有啥区别？。另外，我还试了一下， 仅仅将 Devise 从 2.2.4 升级到 3.2.3 就会引起这个问题。

如何在使用 vagrant 的情况下让两个目录使用同一个 VM？

diguage — Sat, 01 Mar 2014 15:37:29 +0800

之前的项目使用的 VM 已经都装好了各种依赖等等。现在又有一个项目，我把原来项目的Vagrantfile拷贝到新的项目下，使用vagrant up，然后vagrant ssh进入之后发现，竟然是一个新的 VM。我在原来的 VM 中安装、配置的各种东西都没有了。难道还要重新安装一遍？多浪费时间，浪费电脑磁盘空间啊！！

请问：能否修改一下配置等，使得在不同目录（项目）的 vagrant 指定到同一个 VM 下？

Devise2 与 Devise3 有啥区别？

diguage — Fri, 28 Feb 2014 14:59:24 +0800

最近准备搞一下 BBS。@daqing 开发的 Rable，功能听完善。所以，准备拿这个系统来玩玩。

昨天看了看 Rabel 的 Gem，突然发现竟然使用的是 Devise2（2.2.4）。原来的项目中用的是 Devise3。所以，就bundle update升级了一下，Devsie 升级到了3.2.3版。简单测试了一下，登录没有问题。但是，注册总是报用户名、邮箱、密码不能为空（已经填写了），并且注册成功。

请问：

有升级的朋友吗？能分享一下经验吗？

如何配置 Devise，使得注册后，发送确认邮件并登录？

diguage — Thu, 27 Feb 2014 23:37:49 +0800

打开 Devise 的确认模块，注册后，会发送确认邮件，但是并不登录。

如何配置 Devise，使得注册后，发送确认邮件，并且网站也是登录状态？

组团买 Alfred，求加入 (组团完毕)

有 Github 之后，是否无视其他代码托管服务器了？欢迎一起吐槽！

diguage — Tue, 25 Feb 2014 18:17:39 +0800

刚刚搜索 Ruby 爬虫时，在这里看到的一篇帖子里提到了mechanize，我搜索了一下，代码在SourceForge。一点点进去的冲动都没有！

大家来吐槽一下， 是不是有Github之后，其他什么代码托管服务器都无视了？尤其是SourceForge，有巨多广告，而且页面巨丑！

Figaro 支持层次配置吗？引用方式是什么？

diguage — Mon, 10 Feb 2014 16:32:23 +0800

我想使用 Figaro 做配置信息，在 application.yml 中写的配置如下：

配置信息

EMAIL:
  SMTP:
    ADDRESS: <<Address>>
    PORT: <<Port>>
    DOMAIN: <<Domain>>
    AUTHENTICATION: <<Auth>>
    USER_NAME: <<User Name>>
    PASSWORD: <<Password>>
    ENABLE_STARTTLS_AUTO: <<Starttls Auto>>
  DEFAULT_FROM_EMAIL: <<Default Email>>
  DEFAULT_URL: <<Default Url>>

引用以及错误

在 Console 下，如果引用``，没有问题：

2.0.0p353 :004 > Figaro.env.EMAIL
 => "{\"SMTP\"=>{\"ADDRESS\"=>\"<<Address>>\", \"PORT\"=><<Port>>, \"DOMAIN\"=>\"<<Domain>>\", \"AUTHENTICATION\"=>\"<<Auth>>\", \"USER_NAME\"=>\"<<User Name>>\", \"PASSWORD\"=><<Password>>, \"ENABLE_STARTTLS_AUTO\"=><<Starttls Auto>>}, \"DEFAULT_FROM_EMAIL\"=>\"<<Default Email>>\", \"DEFAULT_URL\"=>\"<<Default Url>>\"}"

如果引用Figaro.env.EMAIL.SMTP，则报错：

2.0.0p353 :005 > Figaro.env.EMAIL.SMTP
NoMethodError: undefined method `SMTP' for #<String:0x007fa1280ef940>
    from (irb):5
    from /Users/diguage/.rvm/gems/ruby-2.0.0-p353@rails402/gems/railties-4.0.2/lib/rails/commands/console.rb:90:in `start'
    from /Users/diguage/.rvm/gems/ruby-2.0.0-p353@rails402/gems/railties-4.0.2/lib/rails/commands/console.rb:9:in `start'
    from /Users/diguage/.rvm/gems/ruby-2.0.0-p353@rails402/gems/railties-4.0.2/lib/rails/commands.rb:62:in `<top (required)>'
    from bin/rails:4:in `require'
    from bin/rails:4:in `<main>'

如果引用Figaro.env.EMAIL.SMTP.ADDRESS，也会报上面一样的错误。

Figaro 不支持这种层次配置以及吗？还是我的引用方式不对？（我看网上的一些例子没见过这种层次配置配置的）

注：在群里询问这个问题时，一个朋友说，Figaro 的引用方式是ENV["xxx"]。我试了一下，两种都可以。

然后，搜问题解答，搜到如下解决方法： uninitialized constant BSON::ByteBuffer (Heroku) 安装所述，在Gemfile中，增加如下一行

gem "bson", "~> 2.2.0"

找不到合适版本的 moped

然后，运行运行bundle命令，但是却报如下错误：

ruby-china git:(master) ✗ >bundle
Fetching source index from http://ruby.taobao.org/
Resolving dependencies...
Bundler could not find compatible versions for gem "moped":
  In snapshot (Gemfile.lock):
    moped (1.5.0)

  In Gemfile:
    mongoid (>= 0) ruby depends on
      moped (~> 2.0.beta3) ruby

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

找不到 frontier 分支

根据提示，我运行了bundle update命令，结果又报如下错误：

我查了一下 Grape 的 Github 页面，确实没有frontier的分支了。但是，不知道为什么 RubyChina 的Gemfiel文件中没有更新？

actionpack 依赖版本冲突

我把 Grape 的声明方式修改为gem 'grape'了，目前执行bundle update，但是却报如下错误：

ruby-china git:(master) ✗ >bundle update

      actionpack (= 4.0.2) ruby

    actionpack-action_caching (= 1.0.0) ruby depends on
      actionpack (4.1.0.beta1)

环境

Ubuntu 12.04 32 位
ruby-2.0.0-p247
Rails 4.0.2
MongoDB shell version: 2.4.9
Redis 2.8.3
Memcached 1.4.13

问题列表

uninitialized constant BSON (NameError)--这个通过增加gem bson解决了；
Bundler could not find compatible versions for gem "moped"--提示bundle update，但是目前还没有跑通过。还要再看看；
fatal: ambiguous argument 'frontier': unknown revision or path not in the working tree.--这个通过直接引用gem 'grape'，而不是走 Github 分支，可以了；
Bundler could not find compatible versions for gem "actionpack"

求解答。
