升级 Ubuntu/Ruby 后 Jekyll 崩溃

我在 Ubuntu 笔记本电脑上使用 Jekyll。它适用于 15.10。我升级到 16.04 后收到以下错误消息：

$ jekyll -v
bash: /usr/local/bin/jekyll : /usr/bin/ruby2.1 : bad interpreter: no file or folder

这是已安装的 Ruby 版本：

$ ruby -v
ruby 2.3.0p0 (2015-12-25) [i386-linux-gnu]

我试过了：

$ gem update jekyll
Updating installed gems
Nothing to update

作为which ruby回报/usr/bin/ruby，我已更新/usr/local/bin/jekyll更改#!/usr/bin/ruby2.1为#!/usr/bin/ruby。

现在我得到：

$ jekyll -v
/usr/lib/ruby/2.3.0/rubygems/dependency.rb:319:in 'to_specs': Could not find 'jekyll' (>= 0) among 11 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/home/samuel/.gem/ruby/2.3.0:/var/lib/gems/2.3.0:/usr/lib/i386-linux-gnu/rubygems-integration/2.3.0:/usr/share/rubygems-integration/2.3.0:/usr/share/rubygems-integration/all', execute 'gem env` for more information
    from /usr/lib/ruby/2.3.0/rubygems/dependency.rb:328:in 'to_spec'
    from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:65:in 'gem'
    from /usr/local/bin/jekyll:22:in 'main'

返回结果如下gem env：

$ gem env

答案1

我遇到了同样的问题。这是由新 Ubuntu 中的 ruby​​ 更新引起的。只需卸载 jekyll 并重新安装即可：

gem uninstall jekyll
gem install jekyll

答案2

除了@Piotr的回答之外，我还必须卸载并重新安装 gem bundler。也就是说，我跑了，

gem uninstall bundler
gem install bundler
bundle

只有在我从 ubuntu 18.04 升级到 20.04 后，它才bundle exec jekyll serve开始再次工作。
