无法使用可执行 jekyll (Gem::GemNotFoundException) 找到 gem jekyll (>= 0.a)

Question

我正在尝试按照官方website 上的说明使用 github 和 jekyll 制作我的个人网站

当我到达部分时：

jekyll new --skip-bundle

我收到了：

can't find gem jekyll (>= 0.a) with executable jekyll (Gem::GemNotFoundException)

我尝试了几种方法，例如提到的here，我用sudo运行命令。再次运行 jekyll new --skip-bundle 后。

这是安装后的终端响应 here

Fetching bundler-2.4.5.gem
Successfully installed bundler-2.4.5
Parsing documentation for bundler-2.4.5
Installing ri documentation for bundler-2.4.5
Done installing documentation for bundler after 0 seconds
1 gem installed

这是我再次运行 jekyll new --skip-bundle 时的终端响应：

Traceback (most recent call last):
    2: from /usr/local/bin/jekyll:22:in `<main>'
    1: from /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems.rb:262:in `bin_path'
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems.rb:283:in `find_spec_for_exe': can't find gem jekyll (>= 0.a) with executable jekyll (Gem::GemNotFoundException)

如果您能帮助我解决问题，我将不胜感激。 我使用 macOS。

更新：

我运行 bundle add jekyll 并收到：

Your RubyGems version (3.0.3) has a bug that prevents `required_ruby_version` from working for Bundler. Any scripts that use `gem install bundler` will break as soon as Bundler drops support for your Ruby version. Please upgrade RubyGems to avoid future breakage and silence this warning by running `gem update --system 3.2.3

找不到 Gemfile`

然后我跑gem update --system 3.2.3

Updating rubygems-update
Fetching rubygems-update-3.2.3.gem
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.6.0 directory.
    

下一步我运行sudo gem update --system 3.2.3，我收到了：

所以我仍然没有添加 jekyll ....

注意：将更新我的答案，因为我还不能评论要求澄清

这是按照此处的说明安装后的终端响应

您正在运行它来安装 Bundler（您可以将其视为 gem 存储）。在这里你知道对于 jekyll 错误代码，它有同样的问题（它没有找到运行 jekyll 的源代码）。要解决此问题，请安装 jekyll

如果你想从 bundler 运行 jekyll，试试这个（推荐）Reference

bundle add jekyll #This will add jekyll to Gemfile (gem dependencies manager)
bundle install #This will check/install the gem from Gemfile
bundle exec jekyll #This will run jekyll from the bundle

如果不想使用bundle，可以直接安装gem

gem install jekyll
jekyll #this should work and have message related to jekyll
