Several days earlier I met a strange issue,when imported the library of Alamofire and then let enum conform to protocol .The error shows enum cannot conform to protocol .I thought the issue was from cocoa pods ,so I uninstalled cocoa pods and then wanna install again.
I executed the order:"gem install cocoapods".But it displayed the error,the error as follow,I hope get everyone's help to solve it completely.I'm not skilled in the field of cocoa pods.Thank you so much..
ERROR: Could not find a valid gem 'cocoapods' (>= 0), here is why:
Unable to download data from https://ruby.taobao.org - no such name (https://ruby.taobao.org/specs.4.8.gz)
Sorry to disturb everyone......But I really desire to get your hand to solve it.
Yeah I did it via command order
pod install cocoapods
Sometimes you need to reinstall it and then all will be solved.

I tried a couple of variations in podfile to no avail...I assumed it was pod 'RxSwft', '-> 4.2' but get an error that is less than descriptive.
This works fine for me:
maybe you have another problem, can you add the error description?
And also I would recommend to always follow the page documentation:
there it still says to use 4.0, and even when i used in my podfile 4.0 it still installed (4.2.0) and i use the Xcode 10 beta, working fine.
When I try to install devtools in Rstudio 3.2.3 (Windows 10) using the command install.packages("devtools"), I get the following message:
warning in install.packages :
'lib = "c:/Program Files/R/R-3.2.3//library"' is not writable
I'm a newby and I've been hunting for solutions but so far am coming up empty. I would appreciate any advice that might get me through this step. Thanks.
I stumbled upon the same issue earlier. This "problem" arises when you try to install a library for the first time and R does not have a a dedicated library for it yet.
Two pop-up should appear one after the other when you try to install a package like:
install.packages("ggplot2")
The questions are the following:
Would you like to use a personal library instead?
Would you like to create a personal library 'C:\Users\bartlein\Documents/R/win-library/3.2' to install packages into?
Answer yes to both questions and you should be fine.
The ressources I used came from here.
We have discovered one or more issues with your recent delivery for "AppName". To process your delivery, the following issues must be corrected:
Invalid Bundle - One or more dynamic libraries that are referenced by your app are not present in the dylib search path.
Once these issues have been corrected, you can then redeliver the corrected binary.

For me the following worked:
i updated cocoapods if You have troubles doing so this link may help
deleted MyProjectTests (that i wasn't using)
deleted my Pods/ folder and Podfile.lock
made pod install
rebooted my mac
and the problem is gone
I have just seen the problem after install the app in a real device, but crashed (in the simulator works). My app missing a library installed with Cocoapods.
I apologize ahead of time if I don't do a good job of explaining this. I am a complete beginner and I have been struggling to find anything online that is written with that in mind.
So far, my only experience is doing the Javascript and Ruby sections of Codecademy.com. I read that I should have some knowledge of Ruby before trying out Rails.
So I found this site Getting Started with Rails and I tried to follow the steps and do exactly as it said. It even says at the beginning, "This guide is designed for beginners who want to get started with a Rails application from scratch. It does not assume that you have any prior experience with Rails." It also says, "The best way to use this guide is to follow each step as it happens, no code or step needed to make this example application has been left out, so you can literally follow along step by step."
Anyway, I'm using Windows 7 Home Premium and I already had Ruby installed. When I go into the command prompt and type ruby -v it says ruby 1.9.3p484 (2013-11-22) [i386-mingw32]. When I type rails -v it says 4.0.2. When I type gem -v I get 1.8.28. Now in the instructions it links to a place to download RubyGems and it says that it's 2.2.2. I downloaded that and clicked the setup.rb file and it said it installed it, yet the version is still 1.8.28. I don't know why, but it says it's installed so I assumed it did what it was supposed to do. I'm probably wrong.
Then I'm supposed to type rails server and then go to localhost:3000 and see some kind of default page. However, when I type rails server I get these errors. Sorry for the copy and paste, but I'm not allowed to post a pic of the command prompt.

You can see that it tells me to type bundle install, but when I try that I get another few error messages. I've tried googling these error messages, and some of them even linked me to questions asked on this site, but most of them were close, but not exactly what I'm having trouble with, and all of them have answers that are away over my head.
I also thought maybe it didn't matter and so I tried to go to localhost:3000 anyway, but I get the "Oops! Google Chrome could not connect to localhost:3000" message.
I'm a total noob. Everything I look up just gets me more confused so I'm hoping the answer is kind of simple and that someone can point it out for me in a beginner-friendly kind of way. I feel like once I get over this hump of getting all of this set up, I can actually start learning and gaining some experience. I had a blast learning Ruby so far and I hope to continue on with learning Rails. Thanks for reading and any help would be greatly appreciated. Oh, and if anyone has any better suggestions for a beginner's guide to all of this stuff, I'd also really appreciate it. Thanks again.
On windows it is probably the easiest to get started with the one click rails installer as this will also install the devkit although I see that it is not being kept up to date with ruby or rails versions. Although it does work Windows is not the best environment for Rails development. Starting up the rails server and running tests is much slower than on mac or linux and will get frustrating after a while. Also some handy gems and third party tools doesn't work on windows. Save yourself the pain and run ubuntu on a vm (virtualbox is good). Also use a ruby version manager like rbenv otherwise it becomes a royal pain to upgrade ruby later.
i am running ruby 1.9.2p0 on rails on windows OS with rubymine 3.1.1.
i use it for גseveral weeks.
a few days ago- i tried to run my project from rubymine and the console notification was:
"Could not find rake-0.8.7 in any of the sources
Process finished with exit code 7"
i googled it and i found reference to this problem in several places. the solution repeated most often was to delete the non-versioned "rake.gemspec" file.
i tried this solution but the problem is not resolved, it still says the same notification.
i trying to solve this problem for several days!!!
please help me if you know how!!!
thanks a lot in advanced!
Asaf,
I've had literally hours of frustration dealing with similar problems. The solution can be a challenge to track down, because there are numerous reasons you could be having the problem. I'm no expert myself, but I'll try to pass on some of what I've learned.
First, you mentioned getting an error about Rake, but didn't mention that you had tried to actually run Rake. Are you getting the error upon loading up RubyMine or specifically after running a Rake command?
Next, if you are running a Rake command and getting an error, you should take note that WHERE you run the command from is pretty important. For example, if you keep a Terminal window open like I do, and run the Rake command from Terminal, you won't necessarily get the same results you would get by running Rake from RubyMine itself. The reason for this was not self-evident when I first started with RubyMine, but I think it comes down to this:
The Ruby SDK and Gems preferences in RubyMine should be determining what types of dependency errors you get from within RubyMine. So you might start by looking there to see if there are any dependency errors. Next, I would guess that you're running RVM? Please be aware that it is completely possible to be using one RVM set in RubyMine (check the Ruby Interpreter in SDK and Gems Preferences to see which one you're using) and an entirely different RVM in Terminal (the command "RVM info" should get you the version you're using). If those don't match, you could very well get different results from both RubyMine and Terminal, even when running exactly the same commands.
My solution to this problem was to carefully ensure that both of my environments matched. I think you can set RVM defaults by typing "rvm default" plus the version you want to default to. That way both your Terminal and RubyMine environments match.
Lastly, be aware that RubyMine allows more than one version of a Gem to be installed at the same time. So, if you're getting an error that a Gem is failing because some dependency requires a specific version, you can tell RubyMine to install multiple versions. Do this thru the SDK manager, select the Gem, then click "Select Versions".
Hopefully some of this information applies to your issue. I sort of did the shotgun approach, because I'm not really sure what is causing your error, but maybe some of this can put you on the right path. One final note would be this: Use your Gemfile to control Gem versions, if need be. I've spent hours of frustration over broken dependencies, only to discover that the reason for the break was me telling RubyMine to update all my Gems to the latest version. The latest version of a particular Gem isn't necessarily backwards compatible with previous versions, and blindly updating Gems can cause huge problems.
Asaf, you should delete rake.gemspec and run gem install rake to get problem fixed
