Bundler:在与gem捆绑安装期间，无法找到具有可执行捆绑(Gem :: GemNotFoundException)的gem bundler(& gt; = 0.a)

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gems.

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

宝石列表显示已安装的宝石.我在执行时也可以找到捆绑软件:

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

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

我也尝试安装捆绑软件，但这也无济于事.我在做什么错了?

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

gem捆绑包没有显示任何内容. gem spec捆绑包没有显示它.

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

更新:我在运行捆绑软件之前尝试安装捆绑软件，但在以下时间出现相同的问题:

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

宝石列表包显示

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，如果您现有的 Gemfile.lock 在底部有这样的行

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<2.0.由于您仅安装了Bundler 2.0.1(并且Rubygems> = 2.7.0)，因此失败，并显示此无用的错误消息.

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.

要解决此问题，您可以

• 从 Gemfile.lock 中删除行，然后从现在开始在各处使用bundler 2.x，或者
• 使用 gem install bundler -v'<安装bundler 1.x版本.2.0'以使用您的 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.
