Устранение ошибок сборки Jekyll для сайтов GitHub Pages

Troubleshooting build errors

If Jekyll encounters an error building your GitHub Pages site locally or on GitHub, you can use error messages to troubleshoot. For more information about error messages and how to view them, see About Jekyll build errors for GitHub Pages sites.

If you received a generic error message, check for common issues.

• You're using unsupported plugins. For more information, see About GitHub Pages and Jekyll.
• Your repository has exceeded our repository size limits. For more information, see About large files on GitHub
• You changed the source setting in your _config.yml file. If you publish your site from a branch, GitHub Pages overrides this setting during the build process.
• A filename in your published files contains a colon (:) which is not supported.

If you received a specific error message, review the troubleshooting information for the error message below.

After you've fixed any errors, trigger another build by pushing the changes to your site's source branch (if you are publishing from a branch) or by triggering your custom GitHub Actions workflow (if you are publishing with GitHub Actions).

Config file error

This error means that your site failed to build because the _config.yml file contains syntax errors.

To troubleshoot, make sure that your _config.yml file follows these rules:

• Use spaces instead of tabs.
• Include a space after the : for each key value pair, like timezone: Africa/Nairobi.
• Use only UTF-8 characters.
• Quote any special characters, such as :, like title: "my awesome site: an adventure in parse errors".
• For multi-line values, use | to create newlines and > to ignore newlines.

To identify any errors, you can copy and paste the contents of your YAML file into a YAML linter, such as YAML Validator.

Date is not a valid datetime

This error means that one of the pages on your site includes an invalid datetime.

To troubleshoot, search the file in the error message and the file's layouts for calls to any date-related Liquid filters. Make sure that any variables passed into date-related Liquid filters have values in all cases and never pass nil or "". For more information, see Filters in the Liquid documentation.

File does not exist in includes directory

This error means that your code references a file that doesn't exist in your _includes directory.

To troubleshoot, search the file in the error message for include to see where you've referenced other files, such as {% include example_header.html %}. If any of the files you've referenced aren't in the _includes directory, copy or move the files into the _includes directory.

File is not properly UTF-8 encoded

This error means that you used non-Latin characters, like 日本語, without telling the computer to expect these symbols.

To troubleshoot, force UTF-8 encoding by adding the following line to your _config.yml file:

encoding: UTF-8

Invalid highlighter language

This error means that you specified any syntax highlighter other than Rouge or Pygments in your configuration file.

To troubleshoot, update your _config.yml file to specify Rouge or Pygments. For more information, see About GitHub Pages and Jekyll.

Invalid post date

This error means that a post on your site contains an invalid date in the filename or YAML front matter.

To troubleshoot, make sure all dates are formatted as YYYY-MM-DD HH:MM:SS for UTC and are actual calendar dates. To specify a time zone with an offset from UTC, use the format YYYY-MM-DD HH:MM:SS +/-TTTT, like 2014-04-18 11:30:00 +0800.

If you specify a date format in your _config.yml file, make sure the format is correct.

Invalid Sass or SCSS

This error means your repository contains a Sass or SCSS file with invalid content.

To troubleshoot, review the line number included in the error message for invalid Sass or SCSS. To help prevent future errors, install a Sass or SCSS linter for your favorite text editor.

Invalid submodule

This error means that your repository includes a submodule that hasn't been properly initialized.

To troubleshoot, first decide if you actually want to use a submodule, which is a Git project inside a Git project; submodules are sometimes created accidentally.

If you don't want to use a submodule, remove the submodule, replacing PATH-TO-SUBMODULE with the path to the submodule:

git submodule deinit PATH-TO-SUBMODULE
git rm PATH-TO-SUBMODULE
git commit -m "Remove submodule"
rm -rf .git/modules/PATH-TO-SUBMODULE

If do you want to use the submodule, make sure you use https:// when referencing the submodule (not http://) and that the submodule is in a public repository.

Invalid YAML in data file

This error means that one of more files in the _data folder contains invalid YAML.

To troubleshoot, make sure the YAML files in your _data folder follow these rules:

• Use spaces instead of tabs.
• Include a space after the : for each key value pair, like timezone: Africa/Nairobi.
• Use only UTF-8 characters.
• Quote any special characters, such as :, like title: "my awesome site: an adventure in parse errors".
• For multi-line values, use | to create newlines and > to ignore newlines.

To identify any errors, you can copy and paste the contents of your YAML file into a YAML linter, such as YAML Validator.

For more information about Jekyll data files, see Data Files in the Jekyll documentation.

Markdown errors

This error means that your repository contains Markdown errors.

To troubleshoot, make sure you are using a supported Markdown processor. For more information, see Setting a Markdown processor for your GitHub Pages site using Jekyll.

Then, make sure the file in the error message uses valid Markdown syntax. For more information, see Markdown: Syntax on Daring Fireball.

Missing docs folder

This error means that you have chosen the docs folder on a branch as your publishing source, but there is no docs folder in the root of your repository on that branch.

To troubleshoot, if your docs folder was accidentally moved, try moving the docs folder back to the root of your repository on the branch you chose for your publishing source. If the docs folder was accidentally deleted, you can either:

• Use Git to revert or undo the deletion. For more information, see git-revert in the Git documentation.
• Create a new docs folder in the root of your repository on the branch you chose for your publishing source and add your site's source files to the folder. For more information, see Creating new files.
• Change your publishing source. For more information, see Configuring a publishing source for your GitHub Pages site.

Missing submodule

This error means that your repository includes a submodule that doesn't exist or hasn't been properly initialized.

To troubleshoot, first decide if you actually want to use a submodule, which is a Git project inside a Git project; submodules are sometimes created accidentally.

If you don't want to use a submodule, remove the submodule, replacing PATH-TO-SUBMODULE with the path to the submodule:

git submodule deinit PATH-TO-SUBMODULE
git rm PATH-TO-SUBMODULE
git commit -m "Remove submodule"
rm -rf .git/modules/PATH-TO-SUBMODULE

If you do want to use a submodule, initialize the submodule. For more information, see Git Tools - Submodules in the Pro Git book.

Relative permalinks configured

This errors means that you have relative permalinks, which are not supported by GitHub Pages, in your _config.yml file.

Permalinks are permanent URLs that reference a particular page on your site. Absolute permalinks begin with the root of the site, while relative permalinks begin with the folder containing the referenced page. GitHub Pages and Jekyll no longer support relative permalinks. For more information about permalinks, see Permalinks in the Jekyll documentation.

To troubleshoot, remove the relative_permalinks line from your _config.yml file and reformat any relative permalinks in your site with absolute permalinks. For more information, see Editing files.

Syntax error in 'for' loop

This error means that your code includes invalid syntax in a Liquid for loop declaration.

To troubleshoot, make sure all for loops in the file in the error message have proper syntax. For more information about proper syntax for for loops, see Tags in the Liquid documentation.

Tag not properly closed

This error message means that your code includes a logic tag that is not properly closed. For example, {% capture example_variable %} must be closed by {% endcapture %}.

To troubleshoot, make sure all logic tags in the file in the error message are properly closed. For more information, see Tags in the Liquid documentation.

Tag not properly terminated

This error means that your code includes an output tag that is not properly terminated. For example, {{ page.title } instead of {{ page.title }}.

To troubleshoot, make sure all output tags in the file in the error message are terminated with }}. For more information, see Objects in the Liquid documentation.

Unknown tag error

This error means that your code contains an unrecognized Liquid tag.

To troubleshoot, make sure all Liquid tags in the file in the error message match Jekyll's default variables and there are no typos in the tag names. For a list of default variables, see Variables in the Jekyll documentation.

Unsupported plugins are a common source of unrecognized tags. If you use an unsupported plugin in your site by generating your site locally and pushing your static files to GitHub, make sure the plugin is not introducing tags that are not in Jekyll's default variables. For a list of supported plugins, see About GitHub Pages and Jekyll.
