If issues are detected, Bundler prints them and exits status 1. Otherwise, Bundler prints a success message and exits status 0. .P Examples of common problems caught include: .IP “(bu” 4 Invalid Bundler settings .IP “(bu” 4 Mismatched Ruby versions .IP “(bu” 4 Mismatched platforms .IP “(bu” 4 Uninstalled gems .IP “(bu” 4 Missing dependencies .IP “” 0 .P fBOPTIONSfR .TP fB--quietfR Only output warnings and errors. .TP fB--gemfile=GEMFILEfR 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 fBGemfile.lockfR and fBvendor/cachefR relative to this location. .TP fB--sslfR Diagnose common SSL problems when connecting to rubygems.org. .IP This flag runs the fBbundle doctor sslfR subcommand with default values underneath. .SS “ssl” If you’ve experienced issues related to SSL certificates and/or TLS versions while connecting to rubygems.org, this command can help troubleshoot common problems. The diagnostic will perform a few checks such as: .IP “(bu” 4 Verify the Ruby OpenSSL version installed on your system. .IP “(bu” 4 Check the OpenSSL library version used for compilation. .IP “(bu” 4 Ensure CA certificates are correctly setup on your machine. .IP “(bu” 4 Open a TLS connection and verify the outcome. .IP “” 0 .P fBOPTIONSfR .TP fB--host=HOSTfR Perform the diagnostic on HOST. Defaults to fBrubygems.orgfR. .TP fB--tls-version=VERSIONfR Specify the TLS version when opening the connection to HOST. .IP Accepted values are: fB1.1fR or fB1.2fR. .TP fB--verify-mode=MODEfR Specify the TLS verify mode when opening the connection to HOST. Defaults to fBSSL_VERIFY_PEERfR. .IP Accepted values are: fBCLIENT_ONCEfR, fBFAIL_IF_NO_PEER_CERTfR, fBNONEfR, fBPEERfR.
