Bundler: 在用 Gem 安装包期间，无法找到带有可执行包的 Gem Bundler (> = 0. a)(Gem: : GemNotFoundException)

我正在执行以下脚本:

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

产出:

from /srv/myuser/.gem/ruby/2.5.0/bin/bundle:23:in `<main>'

我已经将 /srv/myuser/.gem/ruby/2.5.0/bin添加到我的路径，所以我能够安装 gem。

gem env节目

gem list显示已安装的 gem。 我还可以在表演时找到 bundle:

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

我也试过安装 bundler，但也没有帮助。 我做错了什么？

gem which bundle什么都没显示，gem spec bundle显示了。

更新: 我试图在运行 bundle 之前安装 bundler，但是同样的问题出现了:

gem list bundle显示

bundle (0.0.1)
bundler (2.0.1)

As per the description mentioned in the post , before running the below mentioned command:

bundle install

in the script, you need to run the below command: 

gem install bundler

So, the sequence of commands to work would be:

gem install bundler
bundle install

Update the bundler command if if does not work to: 

 gem install bundler -v '1.17.3'

Reason for the break in functionalities in bundler 2.0 is given in below mentioned link:

最佳答案

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 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.

To fix this, you could

  • 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.

More information about this can be found on the Bundler blog.

I had the same problem recently. In my case I have installed a version on bundler different from what is logged in the Gemfile.lock. Please check

小开 
gem install bundler -v '< 2.0'

I couldn’t even do bundle -v. This sorted it out:

gem update --system

Got the info from here (similar problem): find_spec_for_exe': can't find gem bundler (>= 0.a) (Gem::GemNotFoundException)

Probably some version mismatch between ruby + gem + bundler

I just faced the same error today. The bundler version which I had installed in my system previously was: 1.16.6

Followed the instructions in the official bundler docs on How to Upgrade to Bundler 2 and the below two steps did the trick:

  1. gem install bundler (Helps you get the latest version of bundler which as of today is 2.0.2)
  2. bundle update --bundler
小开

I faced this same issue. The issue is caused by the fact that RubyGems cannot find an executable bundle for the bundler gem on the system

To fix it, first run

gem install bundler

if you don't have bundler gem installed locally, then run

gem update --system

That's all

I hope this helps

I saw a similar error message for the travis bundle after upgrading mac os to Catalina.

Traceback (most recent call last):
2: from /usr/local/bin/travis:22:in `<main>'
1: from /usr/local/Cellar/ruby/2.6.5/lib/ruby/2.6.0/rubygems.rb:263:in `bin_path'
/usr/local/Cellar/ruby/2.6.5/lib/ruby/2.6.0/rubygems.rb:284:in `find_spec_for_exe': can't find gem travis (>= 0.a) with executable travis (Gem::GemNotFoundException)

To resolve the issue, I reinstalled travis from source.

brew remove travis;
brew install -s travis

You've to install the exact version of Bundler that RubyGems is looking for by running:

$ gem install bundler -v "$(grep -A 1 "BUNDLED WITH" Gemfile.lock | tail -n 1)"

This may help solve the problem

bundle update --bundler

YEP, this works:

gem install bundler -v "$(grep -A 1 "BUNDLED WITH" Gemfile.lock | tail -n 1)"

Perhaps an over-specific (and nooby) answer:

In RubyMine my project was set to Ruby 3.0.0 However, my terminal was using 2.7.6

I used RVM rvm use 3.0.0 to set my terminal to 3.0.0 Problem solved
