Before you start to report a new issue on the GitHubGitHubGitHub is a website that offers online implementation of git repositories that can easily be shared, copied and modified by other developers. Public repositories are free to host, private repositories require a paid subscription. GitHub introduced the concept of the ‘pull request’ where code changes done in branches by contributors can be reviewed and discussed before being merged be the repository owner. https://github.com/ repository, make sure to check your local installation, as some settings may typically result in an unexpected outcome of your WP-CLIWP-CLIWP-CLI is the Command Line Interface for WordPress, used to do administrative and development tasks in a programmatic way. The project page is http://wp-cli.org/https://make.wordpress.org/cli/ commands.
WP-CLI offers the command wp --info, which provides you with a lot of information about your WP-CLI install environment. The output will tell you,
* what operating system and shell you work on
* which PHPPHPPHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. http://php.net/manual/en/intro-whatis.php. binary is used to run WP-CLI
* what version of PHP is used
* where to find WP-CLI’s root directory
* where to find the vendor directory of WP-CLI
* which WP-CLI binary you are currently working with (phar path)
* where WP-CLI packages are stored
* where to find global and project configuration files for WP-CLI and
* which version of WP-CLI you use.
Before you start to debug issues, make sure you are using the latest version of WP-CLI. The latest version may already have solved an issue you experience. The command wp cli update will upgrade your WP-CLI version or confirm you already use the latest version. If the installation hangs, please ensure that you are allowed to connect to GitHub using SSLSSLSecure Socket Layer - Encryption from the server to the browser and back.

Before starting to investigate a bug, you should be aware of the factors that can change the default behavior of WP-CLI and how you can check whether they might be at the root of the issue. There are five main subsystems for modifying this default behavior: environment variables, configuration files, WP-CLI packages, wp-config.php file and WordPress extensions (plugins, themes, must-use plugins, drop-ins).
The setup of your working environment is a prerequisite for running WP-CLI. You can check your current environment settings with the shell command env.
If you want to run WP-CLI remotely using SSHSSHSecure SHell - a protocol for securely connecting to a remote system in addition to or in place of a password., it is required that the command wp is accessible on the path of the remote server. WP-CLI’s behavior can also be changed at runtime through the use of environment variables:
WP_CLI_CACHE_DIR – Directory to store the WP-CLI file cache. Default is ~/.wp-cli/cache/.
WP_CLI_CONFIG_PATH – Path to the global config.yml file. Default is ~/.wp-cli/config.yml.
WP_CLI_DISABLE_AUTO_CHECK_UPDATE – Disable WP-CLI automatic checks for updates.
WP_CLI_PACKAGES_DIR – Directory to store packages installed through WP-CLI’s package management. Default is * ~/.wp-cli/packages/.
WP_CLI_PHP – PHP binary path to use when overriding the system default (only works for non-Phar installation).
WP_CLI_PHP_ARGS – Arguments to pass to the PHP binary when invoking WP-CLI (only works for non-Phar installation).
WP_CLI_SSH_PRE_CMD – When using --ssh=<ssh>, perform a command before WP-CLI calls WP-CLI on the remote server.
WP_CLI_STRICT_ARGS_MODE – Avoid ambiguity by telling WP-CLI to treat any arguments before the command as global, and after the command as local.
To set an environment variable on demand, you can place the environment variable definition before the WP-CLI command you mean to run (e.g. EDITOR=vim wp post edit 1); to overwrite environment variables, use export VARIABLE=value in your ~/.bashrc or ~.zhsrc.
Configuration files let you customize the behavior of WP-CLI to adapt it to your personal needs or those of your project. If the configuration file is incorrect or includes unwanted modifications to the default behavior, the output of WP-CLI will most likely reflect the error.
Note that a project configuration file can override settings in a global configuration file.
Rename or delete your configuration file(s) and compare the result, to find out if a configuration setting might have caused the issue.
WP-CLI packages are community-maintained projects built on WP-CLI. They can contain WP-CLI commands, but they can also just extend WP-CLI in some way. While WP-CLI might be perfectly working, a package with errors can cause unexpected results, too. To skip loading all installed packages, use wp --skip-packages.
Errors may result from moving or editing wp-config.php beyond what WP-CLI supports. If you get a parse error, check the file encoding of your wp-config.php (UTF-8 without BOM).
Make sure that the line require_once(ABSPATH . 'wp-settings.php'); remains in the wp-config.php file and don’t modify wp-config.php beyond constant definitions. If you call WordPress functions within wp-config.php, PHP will fail with a fatal error.
If you want to use $_SERVER['HTTP_HOST'] in your wp-config.php, you’ll need to set a default value in WP-CLI context:
WordPress Themes and Plugins might conflict with the loading process of WP-CLI or interfere e.g. by redirecting users. They often make assumptions that are not true in the WP-CLI context, like using the hostname of the current request (which is a concept that does not exist within command-line context).
You can bypass single plugins and themes (e.g. --skip-plugins=akismet) or skip them entirely (wp --skip-plugins --skip-themes).
Common problems are the result of changes in your wp-config.php or web server configuration. The section “Common issues” of the handbook lists the most common error messages and explains how to handle these errors.
Try to reproduce the issue in a fresh installation of WordPress with a default Theme (Twenty …) and no plugins installed. If the issue only reproduces in a custom environment, then the issue is a bug in your environment, not WP-CLI. Also make sure to enable WordPress’ debugging mode by setting the constant define( 'WP_DEBUG', true ); in your wp-config.php. It may reveal problems with your existing WordPress installation, not caused by WP-CLI.
Additionally you can use WP-CLI’s global parameter --debug to show all PHP errors and add verbosity to WP-CLI bootstrap.
If you think you’ve found a bug, we’d love to hear from you to get it fixed.
