'bundle exec'抱怨没有安装gem，即使'bundle install' [英] 'bundle exec' complains about gem not being installed, even after 'bundle install'

问题描述

我有一个网站使用 Jekyll与Github Pages 。之前在另一台计算机上与版本和RVM混淆后，在这一个版本中，我选择只使用捆绑器的一个版本的Ruby和每个项目环境。

一个非常简单的 Gemfile ：

  [$]> cat Gemfile 
 source'https://rubygems.org'
 gem'github-pages'
  

和bundler config：

  [$]> cat .bundle / config 
 --- 
 BUNDLE_PATH：env 
 BUNDLE_DISABLE_SHARED_GEMS：'1'
  

当我通过 bundle exec 运行任何命令（jekyll，gem，irb）时，出现依赖关系错误：

  [$]> bundle exec jekyll 
在任何源代码中都找不到RedCloth-4.2.9 
运行`bundle install`安装缺失的gem。 
  

但是，该捆绑包已经安装：

  [$]> bundle install 
使用RedCloth 4.2.9 
使用i18n 0.6.11 
使用json 1.8.1 
 [snip] 
使用github页面29 
使用捆绑商1.7.7 
您的捆绑已完成！ 
它被安装到./env 
  

我有点不知所措以及bundler如何使用一个子命令来安装宝石，但认为它们在使用另一个子命令时缺少。

  [$ ] GT; ruby 
 / usr / local / bin / ruby​​ 
 [$]>其中打包者
 / usr / local / bin / bundler 
 [$]> ruby --version 
 ruby​​ 2.2.0p0（2014-12-25 revision 49005）[x86_64-darwin14] 
 [$]> bundler --version 
 Bundler version 1.7.7 
  

解决方案

<删除 env 目录并重新安装后，我发现它为两个Ruby版本创建了子目录 - 2.1.0和2.2.0。后者是我目前使用的Ruby版本，但目录是空的（所有的gem都安装在 env / ruby​​ / 2.1.0 / gems 目录中）。这与Oliver关于rbenv的回答一起让我想到了不匹配的版本。

我用一个简单的 gem install bundler重新安装了捆绑器，reran bundle install ，并且都很好。

看起来总的来说，答案是与安装不同版本的Ruby的捆绑程序相比，您遇到的问题不是您实际使用的。看起来很奇怪，它会为 bundle install 和另一个用于 bundle exec ，但是* shrug * whatever 。

I have a website using Jekyll with Github Pages. After previously messing about with versions and RVM on another computer, on this one I opted to stick with just one version of Ruby and per-project environments using bundler.

I have a pretty simple Gemfile:

[$]> cat Gemfile
source 'https://rubygems.org'
gem 'github-pages'

and bundler config:

[$]> cat .bundle/config
---
BUNDLE_PATH: env
BUNDLE_DISABLE_SHARED_GEMS: '1'

When I run any command (jekyll, gem, irb) through bundle exec, I get a dependency error:

[$]> bundle exec jekyll
Could not find RedCloth-4.2.9 in any of the sources
Run `bundle install` to install missing gems.

However, the bundle is already installed:

[$]> bundle install
Using RedCloth 4.2.9
Using i18n 0.6.11
Using json 1.8.1
[snip]
Using github-pages 29
Using bundler 1.7.7
Your bundle is complete!
It was installed into ./env

I'm at a bit of a loss as to how bundler can think the gems are installed when using one subcommand, but think they're missing when using another.

[$]> which ruby
/usr/local/bin/ruby
[$]> which bundler
/usr/local/bin/bundler
[$]> ruby --version
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14]
[$]> bundler --version
Bundler version 1.7.7

解决方案

After deleting the env directory and reinstalling, I noticed it created subdirectories for two Ruby versions - 2.1.0 and 2.2.0. The latter was my current version of Ruby, but the directory was empty (all the gems were installed into the env/ruby/2.1.0/gems directory). This, combined with Oliver's answer about rbenv, got me thinking about mismatched versions.

I reinstalled bundler with a simple gem install bundler, reran bundle install, and all is good.

It seems in general the answer is to sort out issues with bundler installing for a different version of Ruby than you're actually using. It seems strange to me it would use one thing for bundle install and another for bundle exec, but *shrug* whatever.
