如何在Ruby项目中使用旧版本的Bundler ?

...without uninstalling the latest version.

…不卸载最新版本。

I'm working on a project that uses Bundler 1.10, but I use Bundler 1.11 for all my other projects. Since this project is on 1.10, whenever I run any bundle commands, my Gemfile.lock changes due to the different formatting introduced by Bundler 1.11.

我正在做一个使用Bundler 1.10的项目，但是我使用Bundler 1.11来完成其他项目。因为这个项目在1.10上，所以无论何时运行任何bundle命令，我的Gemfile都会运行。由于Bundler 1.11引入的不同格式而导致的锁更改。

The only solution I've found so far is running all my commands like so:

到目前为止，我发现的唯一解决方案是像这样运行我的所有命令:

bundle _1.10.6_ [command]

(from this answer here: https://*.com/a/4373478/1612744)

(答案如下:https://*.com/a/4373478/1612744)

Is there a better way? I'm using rbenv, not rvm.

有更好的方法吗?我用的是rbenv，不是rvm。

You could use the rbenv-gemset plugin. Since an older version of a gem in an rbenv gemset doesn't override a newer version in the default gemset, you'd need to install bundler for each project, which is rather cumbersome.

你可以使用rbenv-gemset插件。由于rbenv gemset中的旧版本不会覆盖默认gemset中的新版本，因此需要为每个项目安装bundler，这相当麻烦。

Install the plugin (cd ~/.rbenv/plugins; git clone git://github.com/jf/rbenv-gemset.git) OR, if you use homebrew, brew install rbenv-gemset
安装插件(cd ~/.rbenv/插件);或者，如果你使用homebrew, brew安装rbenv-gemset。
gem uninstall -xI bundler

For each project that can use bundler 1.11,
- cd to the project
- cd到项目
- echo bundler-1.11 > .rbenv-gemsets ("bundler-1.11" is the name of the gemset)
- > .rbenv-gemsets(“bundler-1.11”是gemset的名字)
对于可以使用bundler 1.11的每个项目，cd到项目echo bundler-1.11 > .rbenv-gemsets(“bundler-1.11”是gemset的名字)
In one of those projects, gem install bundler to get the current version, 1.11.*
在其中一个项目中，gem安装bundler以获得当前版本1.11.*
For the project that needs bundler 1.10,
- cd to the project
- cd到项目
- echo bundler-1.10 > .rbenv-gemsets ("bundler-1.10" is the name of the gemset)
- echo bundler-1.10 > .rbenv-gemsets(“bundler-1.10”是gemset的名字)
- gem install bundler -v 1.10.6
- gem安装bundler - v1.10.6。
对于需要bundler 1.10的项目，cd到项目echo bundler-1.10 > .rbenv-gemsets(“bundler-1.10”是gemset的名称)gem安装bundler- v1.10.6。

I ended up solving this with an alias and a bash function. In my ~/.bashrc, I added this:

最后我用一个别名和一个bash函数解决了这个问题。在我的~ /。bashrc,(我说的是:

versioned_bundle() {
  version_file=${PWD}/.bundle/version
  if [[ -r $version_file ]]; then
    version=$(<$version_file)
    bundle _${version}_ "$@"
  else
    bundle "$@"
  fi
}
alias bundle=versioned_bundle

As you can guess from the code, I also added a version file to the .bundle/ directory in my project. That file's contents:

您可以从代码中猜到，我还向项目中的.bundle/目录添加了一个版本文件。该文件的内容:

1.10.6

Whenever I run bundle, my shell checks for a version file in the current directory, and if it finds it, runs that version of bundle.

每当我运行bundle时，我的shell检查当前目录中的版本文件，如果它找到了，就运行该版本的bundle。

$ cd project-with-old-bundle-version
$ bundle --version
1.10.6
$ cd anywhere-else
$ bundle --version
1.11.2
