version

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: SVN / Subversion 1.7 and Eclipse Subversive & JavaHL I'm using Subversion with version 1.6.5 on the server. I use Subclipse (version 1.6) in STS as a client for certain tasks, but I more commonly use a 1.7.0 subversion command-line client. Why 1.7 for the command-line client? No good reason. So I made a branch with the command-line client, and now when I try to use Subclipse to "Update to HEAD", it tells me: org

问题 I need to update rubygems from 1.3.5 to 1.4.2 but apparently rubygems update just updates you to the latest version How can I update to 1.4.2? 回答1: You can install specific versions of RubyGems using RVM. rvm rubygems 1.4.2 回答2: After some research this worked for me: gem install -v 1.4.2 rubygems-update && ruby `gem env gemdir`/gems/rubygems-update-1.4.2/setup.rb If you need to use sudo to install gems then make sure to put a sudo in both calls: sudo gem install -v 1.4.2 rubygems-update &&

问题 In the following manifest, is it necessary to change the version attribute of the assemblyIdentity element if the assembly version is specified in the project (or, in my case, set as part of a MSBuild task)? According to this Microsoft Connect page, it looks like the project's version number overrides the manifest's version number. Please correct me if I'm wrong... <?xml version="1.0" encoding="utf-8"?> <asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1

问题 There are two R directories on my computer: one is /home/R-2.15.2 ,the other is /home/R-2.15.1 , when I input R , I can start R, now I want to know which R is running: 2.15.1 or 2.15.2? 回答1: Run R --version there's info about version on the first line. Edit: If you ask this question then I bet that R is not running from any of these directories. Check $PATH env variable to get information where binaries are looked for and in which order. Edit 2: Use type shell command to find where binary for

问题 I've been unable to find any easy way of figuring out the version string for a WAR file deployed with Tomcat 7 versioned naming (ie app##version.war). You can read about it here and what it enables here. It'd be nice if there was a somewhat more supported approach other than the usual swiss army knife of reflection powered ribcage cracking: final ServletContextEvent event ... final ServletContext applicationContextFacade = event.getServletContext(); final Field applicationContextField =

问题 I've got an application that links against OS X's Python.framework. Since Snow Leopard has upgraded to Python 2.6, the framework now contains versions for 2.4, 2.5, and 2.6. My program doesn't seem to want to link against 2.6, though, and this ends up causing errors when I try and use features from the newer Python runtime. I know I can just use install_name_tool to change the linking in a post-build step, but is there any way to simply tell it where to link during the build? Seems like a

问题 I know it's possible to get the Ruby version (e.g. "1.9.3") via the RUBY_VERSION constant. However, I want to know how to go about determining the exact version (e.g.: "1.9.3-p0"). The reason is that there is a bug that was not fixed in earlier versions of Ruby 1.9.3 that is working in later versions, and I want some code in a gem I'm working on to account for this. 回答1: There is a RUBY_PATCHLEVEL constant as well. So you can get your version string as "#{RUBY_VERSION}-p#{RUBY_PATCHLEVEL}"

问题 How do App Engine version numbers work? Are they only integers? Can I use floats? Can I reuse old version numbers? 回答1: From the manual: http://code.google.com/appengine/docs/python/config/appconfig.html#Required_Elements A version specifier for the application code. App Engine retains a copy of your application for each version used. An administrator can change which major version of the application is default using Administration Console, and can test non-default versions before making them

问题 I saw many posts related to the browser detection, User agent detection etc...I want to detect the version from server side and send appropriate data based on that. I know browsers can mimic version with tools, but that doesn't matter for me. I need the java solution for the exact version detection. 回答1: Take a look at user-agent-utils. 回答2: Here is the code explaining how to do it using user-agent-utils : String userAgent = req.getHeader("user-agent"); UserAgent ua = UserAgent
