问题 I am trying to install a rubygem which keeps on trying to read a library which is not available. grep: /usr/lib64/libgdbm.la: No such file or directory /bin/sed: can't read /usr/lib64/libgdbm.la: No such file or directory libtool: link: /usr/lib64/libgdbm.la' is not a valid libtool archive In order to work around this, I installed my own libgdbm and provided the path to the libgdbm in the makefile LDFLAGs but to no avail. Any help is much appreciated. 回答1: This rubygem seems to do dirty stuff

问题 I have ruby 2.0.0p247 [x64-mingw32] with Gem 2.2.2 installed on Windows 8. I have a persistent problem gem that is making it virtually unusable. Whenever I try to install a new gem, I invariably get: ERROR: While executing gem ... Invalid spec cache file in C:/Users/... In the past, I've been able to run gem update or gem update --system and that would clear up the problem for one, single gem install . Subsequent install would fail with the same error. Now even gem update fails with that

问题 I am using Ruby on Rails 3.2.2. and I would like to know if the following thought (born from my previous question) is correct: I tend not to use third-party gems (at least when it is possible and reasonable) because they might be abandoned at any time. Also, if the Ruby on Rails framework changes, I might have to wait for those gems to be updated before updating my application to the latest RoR version. 回答1: In a perfect world where you're immortal, have infinite time, are the world's best

问题 I'm trying to release my first gem to Ruby Gems. The gem is working great locally. I'm releasing it using: $rake release Which gives me this in the console: example_gem 0.0.3 built to pkg/example_gem-0.0.1.gem Tagged v0.0.1 Pushed git commits and tags Then the process hangs. I waited 20 mins, then cancelled. When I tried to release again I got: rake aborted! This tag has already been committed to the repo. So I assumed the gem had been successfully submitted, however 16 hours later, the gem

问题 I was doing development on a ruby on a rails application (v2.3) yesterday and decided to update my iMac to OSX Mavericks. Now, every time I try to run my application locally, I get the following error. Does anyone know whats causing this? Run like this: script/server -e development Error: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- script/../config/boot (LoadError) from /System/Library

问题 Strange... but this is what I got : $ gem list | grep rvm >> rvm (1.11.3.3) $ gem uninstall rvm >> INFO: gem "rvm" is not installed How can that be possible? The root of this problem probably stems from me downloading the latest RVM and finding that it does not work with the latest version of POW. Thus I had to implode RVM and reinstall an older version. Since then when I do a cap deploy , I get the classic : `<top (required)>': RVM - Capistrano integration was extracted to a separate gem,
