bundle doctor help [COMMAND]

Description

You can diagnose common Bundler problems with this command such as checking gem environment or SSL/TLS issue.

Sub-commands

Diagnose (default Command)

Checks your Gemfile and gem environment for common problems. If issues are detected, Bundler prints them and exits status 1. Otherwise, Bundler prints a success message and exits status 0.

Examples of common problems caught include:

• Invalid Bundler settings
• Mismatched Ruby versions
• Mismatched platforms
• Uninstalled gems
• Missing dependencies

OPTIONS

--quiet

Only output warnings and errors.

--gemfile=GEMFILE

The location of the Gemfile(5) which Bundler should use. This defaults to a Gemfile(5) in the current working directory. In general, Bundler will assume that the location of the Gemfile(5) is also the project's root and will try to find Gemfile.lock and vendor/cache relative to this location.

--ssl

Diagnose common SSL problems when connecting to https://rubygems.org.

This flag runs the bundle doctor ssl subcommand with default values underneath.

Ssl

If you've experienced issues related to SSL certificates and/or TLS versions while connecting to https://rubygems.org, this command can help troubleshoot common problems. The diagnostic will perform a few checks such as:

• Verify the Ruby OpenSSL version installed on your system.
• Check the OpenSSL library version used for compilation.
• Ensure CA certificates are correctly setup on your machine.
• Open a TLS connection and verify the outcome.

OPTIONS

--host=HOST

Perform the diagnostic on HOST. Defaults to rubygems.org.

--tls-version=VERSION

Specify the TLS version when opening the connection to HOST.

Accepted values are: 1.1 or 1.2.

--verify-mode=MODE

Specify the TLS verify mode when opening the connection to HOST. Defaults to SSL_VERIFY_PEER.

Accepted values are: CLIENT_ONCE, FAIL_IF_NO_PEER_CERT, NONE, PEER.
