捆绑器:在使用 gem 进行捆绑安装期间找不到带有可执行捆绑 (Gem::GemNotFoundException) 的 gem 捆绑器 (>= 0.a) [英] Bundler: can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException) during bundle install with gem

问题描述

我正在执行以下脚本:

gem install rdoc --no-document
gem install bundle
bundle

输出:

+ gem install rdoc --no-document
Successfully installed rdoc-6.1.1
1 gem installed
+ gem install bundle
Successfully installed bundle-0.0.1
Parsing documentation for bundle-0.0.1
Done installing documentation for bundle after 2 seconds
1 gem installed
1 gem installed
+ bundle install
/usr/lib/ruby/2.5.0/rubygems.rb:289:in `find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)
    from /usr/lib/ruby/2.5.0/rubygems.rb:308:in `activate_bin_path'
    from /srv/myuser/.gem/ruby/2.5.0/bin/bundle:23:in `<main>'

我已将 /srv/myuser/.gem/ruby/2.5.0/bin 添加到我的路径中，以便能够安装 gem.

I've added /srv/myuser/.gem/ruby/2.5.0/bin to my path so I was able to install gems.

gem env 显示

gem list 显示已安装的 gem.我也可以在执行时找到捆绑包:

gem list shows the installed gems. I can also find bundle when I perform:

ls -ltrah /srv/myuser/.gem/ruby/2.5.0/bin

我也尝试安装 bundler，但这也无济于事.我做错了什么?

I've also tried to install bundler but that didn't also help. What am I doing wrong?

gem which bundle 什么也没显示.gem spec bundle 正在显示.

gem which bundle is showing nothing.gem spec bundle is showing it.

更新:我尝试在运行 bundle 之前安装 bundler，但出现同样的问题:

Update: I tried to install bundler before running bundle but the same issue appears while:

宝石列表包展示

bundle (0.0.1)
bundler (2.0.1)

推荐答案

Bundler 版本 2 引入了一项新功能，可以自动使用项目的 Gemfile.lock 中指定的 Bundler 版本.因此，如果您有一个现有的 Gemfile.lock，底部有这样一行

Bundler version 2 introduced a new feature to automatically use the version of Bundler specified in the Gemfile.lock of your project. Thus, if you have an existing Gemfile.lock with a line like this at the bottom

BUNDLED WITH
   1.17.3

Bundler 将尝试使用 Bundler 版本运行 <2.0.由于您刚刚安装了 Bundler 2.0.1(和 Rubygems >= 2.7.0)，因此失败并显示此相当无用的错误消息.

Bundler will try to run with a Bundler version < 2.0. Since you just have Bundler 2.0.1 (and Rubygems >= 2.7.0) installed, this fails with this rather unhelpful error message.

要解决这个问题，您可以

To fix this, you could

• 从您的 Gemfile.lock 中删除这些行并从现在开始在任何地方使用 bundler 2.x，或者
• 使用 gem install bundler -v '< 安装 bundler 1.x 版本2.0' 使用您的 Gemfile.lock 指定的适当版本.

• remove the lines from your Gemfile.lock and to use bundler 2.x everywhere from now on, or
• install a bundler 1.x version with gem install bundler -v '< 2.0' to use the appropriate version as specified by your Gemfile.lock.
