当我运行Rails 4.1.2服务器时,我没有错误.
但是,如果我运行'rails c',我会收到以下错误:
Could not find activesupport-4.1.2 in any of the sources
Run `bundle install` to install missing gems.
奇怪的是,activesupport-4.1.2已经安装并在Gemfile.lock中指定.我尝试过'捆绑更新'以及删除Gemfile.lock并运行'bundle install'.我也尝试在我的Rails gemfile中指定特定版本的ActiveSupport,但这已经无处可去了.
我真的很想使用最新的Rails,但是我不能使用控制台似乎很糟糕.
FIY:我在Linux中使用Ruby 2.1.2p95和RVM.
编辑:我卸载了所有activesupport宝石并重新安装4.1.2.这是'宝石列表activesupport说':
*** LOCAL GEMS ***
activesupport (4.1.2)
同样的问题.
EDIT2:这是我的Gemfile.lock:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

../src/cached-powers.cc:136:18: error: unused variable 'kCachedPowersLength' [-Werror,-Wunused-const-variable]

当使用以下内容时,我试图告诉clang不要输出错误,但无效但结果是相同的:
ARCHFLAGS=-Wno-error=unused-const-variable gem install libv8 -v '3.11.8.13'
我错过了什么命令行选项？
谢谢
我正在使用Jekyll创建一个静态网站,并希望使用该框架Bourbon来构建我的CSS.
我已经安装了Jekyll并希望通过使用并运行将其添加到我的Gemfile来安装Bourbon.gem 'bourbon'bundle install
现在,当我将规则添加@import 'bourbon';到我的SCSS文件并开始运行Jekyll时,jekyll serve -w它启动了,但是当我修改我的SCSS文件时,Jekyll观察者抛出一个错误说:
Regenerating: 1 files at 2014-07-03 10:00:11 `Conversion error: There was an error converting 'css/main.scss'.`
...error:
Error: File to import not found or unreadable: bourbon. Load path: /Users/mark/Code/markdejong.com/mistermark.github.com.jekyll/_sass
Error: Run jekyll build --trace for more information.
这可能是什么问题？不应该像这样导入它或者杰基尔不支持这个吗？
我整年都在终端使用撬没有任何问题.但是从昨晚开始,每当我在终端中键入pry时,它都不会打开,而是给我一个很长的错误记录.我尝试了几件事,花了很多时间搜索,但我迷路了,不知道接下来该做什么.我不明白为什么它给了我一些具有不同错误的ruby文件的行号,因为它通常在不与文件相关的情况下工作.日志有点长,但错误会重复出现.我把一切都放在重要的事情上.我非常感谢一些指导.

我尝试通过将建议的行添加到我的Rails项目的Gemfile来安装rubocop:
gem 'rubocop', require: false
运行后bundle,它会安装并在我的Gemfile.lock中可见.
但是,当$ rubocop从我的应用程序的根运行时,我收到此错误:
-bash: rubocop: command not found
我试过跑步$ which rubocop,什么都没发生.
我也试过跑步$ gem install rubocop,行为没有区别.
以下是我的Gemfile.lock的摘录:
rubocop (0.27.0)
astrolabe (~> 1.3)
parser (>= 2.2.0.pre.6, < 3.0)
powerpack (~> 0.0.6)
rainbow (>= 1.99.1, < 3.0)
ruby-progressbar (~> 1.4)
我rake尝试安装时遇到一个奇怪的错误,这就是它所说的

当我尝试导航到目录时,我什么也没找到:
$ ls /usr/share/rubygems-integration/1.9.1/

Ruby版本:
$ ruby -v

为什么它试图加载错误的版本以及如何解决这个问题？
