Question

Following the official update guide, I recently upgraded from Jekyll 2.x to Jekyll 3.1.1.

After the installation, running jekyll serve produced the following error:

Dependency Error: Yikes! It looks like you don't have jekyll-markdown-block or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is: 'Unable to activate jekyll-markdown-block-1.1.0, because jekyll-3.1.1 conflicts with jekyll (~> 2.0)' If you run into trouble, you can find helpful resources at http://jekyllrb.com/help/!

So from there I sudo gem update jekyll-markdown-block, but the error still persisted. I then tried to update all of my gems:

sudo gem update `gem list | cut -d ' ' -f 1`

And then out of desperation, uninstalled all of my gems (except the core one, which I was not permitted to uninstall):

sudo gem uninstall `gem list | cut -d ' ' -f 1`

I then proceeded to install jekyll like normal (assuming I was now working from a clean slate):

sudo gem install jekyll
Fetching: liquid-3.0.6.gem (100%)
Successfully installed liquid-3.0.6
Fetching: kramdown-1.9.0.gem (100%)
Successfully installed kramdown-1.9.0

After then installing jekyll-press and jekyll-markdown-block (a new error message complained I didn't have them), I then received the original error message complaining about Jekyll 2.x.

How can I fully remove Jekyll 2.x and complete the upgrade without gem dependency errors?

Answer 1

从2.x更新到jekylls 3.1.2后，我遇到了同样的问题。运行jekyll serve，我收到以下消息：

依赖性错误：哎呀！看起来你没有安装kramdown或其中一个依赖项。目前使用Jekyll 配置好后，你需要安装这个gem。完整的错误消息来自Ruby的是：'无法加载这样的文件 - kramdown'如果你碰到了麻烦，您可以在http://jekyllrb.com/help/找到有用的资源！

我做了Virtua Creative对他评论的建议：

bundle install

然后：

bundle exec jekyll serve

初始命令给了我同样的错误，但bundle exec有效。

Answer 2

似乎捆绑的环境很混乱。如果您有权限问题，请尝试bundle clean --force - 使用sudo。

Answer 3

确保已安装捆绑包

sudo gem install bundler
