Why does installing Ruby on Rails generate error "size of array 'ruby_check_sizeof_voidp' is negative"? -

-

रेल पर रूबी ( gem install rails के माध्यम से) स्थापित करने पर आपको निम्न त्रुटि संदेश मिल सकता है: 

  c: /Ruby193/include/ruby-1.9.1/ruby/ruby.h: 109: 14: त्रुटि: सरणी का आकार 'ruby_check_sizeof_voidp' ऋणात्मक है   
 इस तरह से कई चेतावनियां भी होंगी:  
  c: /Ruby193/include/ruby-1.9.1/ruby/ruby.h: 1333: 12: चेतावनी: डाली विभिन्न आकार के पूर्णांक से सूचक [-विंग-टू-पॉइंटर-कास्ट]   
 और एक अतिरिक्त त्रुटि  
  c: / ruby193 / include / ruby- 1.9.1 / ruby ​​/ missing.h: 41: 8: त्रुटि: 'struct timespec' का पुनः परिभाषा   
 ऐसा क्यों होता है और मैं रेल को सफलतापूर्वक कैसे स्थापित कर सकता हूं?  < / Div> 
 
 
 यह तब होता है जब आपने रूबी के आपके संस्करण के लिए DevKit का गलत संस्करण स्थापित किया है, उदाहरण के लिए, अगर आपने  देवकीट-मिंगव 64-64-4.7.2-20130224-1432-sfx.exe  रूबी संस्करण 1.9.3 में।  
 वही सही करने के लिए ई समस्या, रूबी को फिर से स्थापित करें और रूबी के आपके संस्करण के लिए सही देवकीट को स्थापित करें, जैसा कि "कौन सा विकास किट?" पर।

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
