问题描述
我的jekyll博客模板包含资源和页面的链接，如下所示：
My jekyll blog template have links to resources and pages like so:
{{ site.url }}/my-page.html
这在部署中效果很好，但是当我运行 jekyll服务时在开发过程中，所有链接都指向实时页面而不是开发页面。
This works well in deployment, but when I run jekyll serve in development, all of the links point to the live page instead of the development page.
my-site-url/my-page.html
# But I want this in development
localhost:4000/my-page.html
有没有办法让jekyll在开发中使用不同的 {{site.url}} ？
Is there a way to make jekyll use a different {{ site.url }} in development?
推荐答案
这是不同Jekyll环境之间的常见问题。
This is a common problem between different Jekyll environments.
我们需要了解 site.url 和 site.baseurl 以及我们需要它们的情况。
这些变量的用途不同。
We need to understand site.url and site.baseurl and in which situation we need them.Those variables don't serve the same purpose.
默认情况下，此变量仅在页头中用于规范标题和 RSS链接。它也在xml提要中用于指向站点资源，因为管理此提要的软件不知道资源的URL。
By default, this variable is only used in page head for the canonical header and the RSS link. It's also used in the xml feed to point to site resources as the software that will manage this feed doesn't know resource's urls.
此变量仅对外部系统是必需的。
This variable is only necessary for external systems.
此变量表示您的Jekyll网站的根文件夹。默认情况下，它设置为（空字符串）。这意味着您的Jekyll网站位于 http://example.com 的根目录。
This variable indicates the root folder of your Jekyll site. By default it is set to "" (empty string). That means that your Jekyll site is at the root of http://example.com.
如果您的Jekyll网站位于 http://example.com/blog ，您必须将 site.baseurl 设置为 / blog （注意斜杠）。这将允许资产（css，js）正确加载。
If your Jekyll site lives in http://example.com/blog, you have to set site.baseurl to /blog (note the slash). This will allow assets (css, js) to load correctly.
查看资产如何加载到您的头上：
See how assets are loaded in you head :
<link rel="stylesheet" href="{{ "/css/main.css" | prepend: site.baseurl }}">
也可以是：
<link rel="stylesheet" href="{{ site.baseurl }}/css/main.css">
在不同的环境中工作
现在你必须在本地测试您的网站并将其部署到生产环境中。有时， baseurl 是不同的， jekyll build 可能无法在其中一个环境中开箱即用。
Working in different environments
Now you have to test your site locally and to deploy it in production. Sometimes, the baseurl is different and the jekyll build may not work out of the box in one of those environment.
这里我们有两个解决方案：
Here we have two solutions :
让我们假设您的网站位于github存储库中，并在 https://username.github.io/myProject 。
Let's imagine that your site lives in a github repository and is served at https://username.github.io/myProject.
您可以将 baseurl 设置为 / myProject 。并使用 jekyll serve 在本地测试您的网站，您的网站将以 http://127.0.0.1:4000/myProject/
You can setup the baseurl to /myProject. and test your site locally with jekyll serve, your site will be served at http://127.0.0.1:4000/myProject/
如果由于某种原因，您无法使用 jekyll serve ，您可以为环境和 jekyll build 设置配置文件，具体取决于您的部署位置。
If, for one reason or another, you cannot use jekyll serve, you can set a configuration file for both environment and jekyll build depending on where you are deploying.
假设我们的本地网站服务于 http：// localhost ，生产网站服务于 https://username.github.io/myProject 。
Let's say we have the local site served at http://localhost and the production site served at https://username.github.io/myProject.
我们离开 _config.yml with url：https：//username.github.io 和 baseurl：/ myProject
We leave the _config.yml with url: https://username.github.io and baseurl: /myProject
我们创建一个新的 _config_dev.yml 只有 url：https：// localhost 和 baseurl：
We create a new _config_dev.yml with only url: https://localhost and baseurl: ""
现在在本地测试：
jekyll build --config _config.yml,_config_dev.yml
或
jekyll build --config _config.yml,_config_dev.yml --watch
按生产时， jekyll build 命令将使用默认 _config.yml 。
When pushed on production, the jekyll build command will use the default _config.yml.
