ruby -/usr/bin/jekyll : No such file or directory

Question

我在使用 jekyll 时遇到了麻烦。我有 Ubuntu 14.04。我曾尝试使用 rack-jekyll 部署一个静态站点，但最终弄乱了我的 ruby​​ 和 jekyll 安装文件。

我已经让 ruby​​ 工作得很好(我使用 rbenv 安装了 2.2.3 版)，但我在使用 jekyll 时仍然遇到问题。当我输入 jekyll new smth 或 jekyll serve 它显示:

bash: /usr/bin/jekyll: No such file or directory

我已经安装了 jekyll，但它仍然显示。根据我的搜索，这可能是某些路径的问题。

以下是一些可能有助于找到解决方案的信息:

这个问题可以通过创建指向 jekyll 可执行文件的符号链接(symbolic link)来解决:

sudo ln -s/path/to/project/gems/bin/jekyll/usr/bin/jekyll

使用 which 命令确定 jekyll 可执行文件的安装位置。
