rbenv

问题 I am able to install and execute a gem as follows: rbenv install 2.4.1 rbenv local 2.4.1 # enter the environment gem install fpm fpm --version I was expecting to be able to execute the gem from outside the environment too, something like: rbenv local --unset # leave the environment rbenv rehash # update shims fpm --version But instead I get: rbenv: fpm: command not found The `fpm' command exists in these Ruby versions: 2.4.1 Have I misunderstood how rbenv shims work? Can I execute a gem from

问题 In my rails project, when I try to run bundle install , I get the following error: Your Ruby version is 2.3.7, but your Gemfile specified 2.5.3 However, when I run ruby --version I get: ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-darwin18] ...and running rbenv version gives me: 2.5.3 (set by /Users/jamesmulholland/proj/repo-name/.ruby-version) What is cauing this the wrong version of Ruby to be used here, and how do I fix it?

问题 I read in "rbenv can't change global ruby version" that I need to add ~/.rbenv/bin to my PATH for rbenv to work. It's also mentioned in the documentation but that directory doesn't exist as shown below: ➜ ~ ls -a ~/.rbenv/ . .. plugins shims version versions So why do I need to add a directory that doesn't exist to my path for rbenv to work? Edit: @theTinMan, I've tried uninstall and reinstalling, but I still don't have a ~/.rbenv/bin path. Where are you seeing in the documentation that it

问题 I've successfully installed rbenv (along with the build tools) on my Ubuntu 14.04 desktop, and that appears to be working fine, but as soon as I try to install ruby 2.1.1, the build fails: daniel@grape:~$ rbenv install 2.1.1 Downloading yaml-0.1.6.tar.gz... -> http://dqw8nmjcqpjn7.cloudfront.net/5fe00cda18ca5daeb43762b80c38e06e Installing yaml-0.1.6...

问题 I was heavily struggling with my Capistrano Setup, when my Hoster migrated the server: Capistrano3 deploy fails after migrating the server One thing I ran into that used to work just fine on the old machine and now seems to be a mess is bundler: I could successfully run bundler through Capistrano: cap staging bundler:install This resulted in the following command on the server /usr/bin/env bundle install --binstubs \ /var/www/mydomain.com/subdomains/dev/shared/bin \ --path /var/www/mydomain

问题 Using brew I go though the normal install process to get rbenv and Ruby installed. Everything goes smoothly but it is soon apparent Ruby did not install with openssl onboard. The only thing that seems to allow rbenv to auto install openssl during the ruby install is to use this: sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include /usr/include Is this a bug in rbenv or brew that needs fixing? 回答1: There's a long thread

问题 I have trouble getting my Rails app running after I deployed this to my DO droplet. I deployed (and installed everything including rbenv ) following this guide. Rbenv seems to be installed properly but app is not running and nginx error log says " cannot execute /root/.rbenv/shims/ruby permission denied (13) " I can not get the sense of this error, hope anyone can help with that. 回答1: Looks like rbenv's installed under root. It should probably be installed under your (or your app user's) home

问题 I recently created a VPS on DigitalOcean to host a rails app. I followed their guide to setup Unicorn with my application. https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-unicorn-and-nginx-on-ubuntu-14-04 A problem occurred when I ran sudo service unicorn_appxyz start . The error given was -su: bundle: command not found I traced the init.d script and pasted the evaluated server start up command in terminal and it works fine when executed under the user joe (the
