Jekyll更新后导致:check_for_activated_spec错误

jekyll 3.8.3 升级到 3.8.5 后, 运行 jekyll --version 报错.
‘check_for_activated_spec!’: You have already activated jekyll 3.8.5, but your Gemfile requires jekyll 3.8.3. Prepending bundle exec to your command may solve this. (Gem::LoadError)

Github安全报警

昨天收到 Github 的一封邮件, 说是 Jekyll 3.8.3 有潜在的安全漏洞, 建议升级到 3.8.4 之后版本

Known moderate severity security vulnerability detected in
jekyll >= 3.8.0, < 3.8.4 defined in Gemfile.lock.
Gemfile.lock update suggested: jekyll ~> 3.8.4.

jekyll升级

启动报错

$ jekyll --version

按照提示加 bundle exec 前缀后, 运行没啥问题, 应该是其他依赖的东西有问题了 (记得切换到博客根目录)

$ bundle exec jekyll --version
jekyll 3.8.3

解决

干脆来个全套的

# 重新安装一遍
$ gem install bundler jekyll

# 更新所有的 gems
$ bundle update

# 测试
$ jekyll --version
jekyll 3.8.5

然后你会发现博客根目录的 Gemfile.lock 文件里的依赖也相应的更新了, 提交并同步到 Github 搞定
