About Jekyll build errors

Sometimes, GitHub 页面 will not attempt to build your site after you push changes to your site's publishing source.

You're pushing with a deploy key. If you want to automate pushes to your site's repository, you can set up a machine user instead. For more information, see "Managing deploy keys" in GitHub 开发者文档.
You're using a CI service that isn't configured to build your publishing source. For example, Travis CI won't build the gh-pages branch unless you add the branch to a safelist. For more information, see "Customizing the build" on Travis CI, or your CI service's documentation.

Note: It can take up to 20 minutes for changes to your site to publish after you push the changes to GitHub Enterprise.

If Jekyll does attempt to build your site and encounters an error, you will receive a build error message. Jekyll 构建错误消息有两种主要类型。

A "Page build warning" message means your build completed successfully, but you may need to make changes to prevent future problems.
A "Page build failed" message means your build failed to complete. If Jekyll is able to detect a reason for the failure, you'll see a descriptive error message.

For more information about troubleshooting build errors, see "Troubleshooting Jekyll build errors for GitHub 页面 sites."

We recommend testing your site locally, which allows you to see build error messages on the command line, and addressing any build failures before pushing changes to GitHub Enterprise. For more information, see "Testing your GitHub 页面 site locally with Jekyll."

When you push changes to your publishing source on GitHub Enterprise, GitHub 页面 will attempt to build your site. If the build fails, you'll receive an email at your primary email address. You'll also receive emails for build warnings.

You will only receive an email if outbound email support is enabled on 您的 GitHub Enterprise Server 实例. For more information, contact your site administrator.

You can see build failures (but not build warnings) for your site on GitHub Enterprise in the Settings tab of your site's repository.

You can configure a third-party service, such as Travis CI, to display error messages after each commit.

If you haven't already, add a file called Gemfile in the root of your publishing source, with the following content:
```
source `https:/rubygems.org`
gem `github-pages`
```
Configure your site's repository for the testing service of your choice. For example, to use Travis CI, add a file named .travis.yml in the root of your publishing source, with the following content:
```
language: ruby
rvm:
  - 2.3
script: "bundle exec jekyll build"
```
You may need to activate your repository with the third-party testing service. For more information, see your testing service's documentation.
