.. _`Logging`:
|
|
|
|
Logging
|
|
=======
|
|
|
|
Console logging
|
|
~~~~~~~~~~~~~~~
|
|
|
|
pip offers :ref:`-v, --verbose <--verbose>` and :ref:`-q, --quiet <--quiet>`
|
|
to control the console log level. Each option can be used multiple times and
|
|
used together. One ``-v`` increases the verbosity by one, whereas one ``-q`` decreases it by
|
|
one.
|
|
|
|
The series of log levels, in order, are as follows::
|
|
|
|
VERBOSE_DEBUG, DEBUG, INFO, NOTIFY, WARN, ERROR, FATAL
|
|
|
|
``NOTIFY`` is the default level.
|
|
|
|
A few examples on how the parameters work to affect the level:
|
|
|
|
* specifying nothing results in ``NOTIFY``
|
|
* ``-v`` results in ``INFO``
|
|
* ``-vv`` results in ``DEBUG``
|
|
* ``-q`` results in ``WARN``
|
|
* ``-vq`` results in ``NOTIFY``
|
|
|
|
The most practical use case for users is either ``-v`` or ``-vv`` to see
|
|
additional logging to help troubleshoot an issue.
|
|
|
|
|
|
.. _`FileLogging`:
|
|
|
|
File logging
|
|
~~~~~~~~~~~~
|
|
|
|
pip offers the :ref:`--log <--log>` option for specifying a file where a maximum
|
|
verbosity log will be kept. This option is empty by default. This log appends
|
|
to previous logging.
|
|
|
|
Additionally, when commands fail (i.e. return a non-zero exit code), pip writes
|
|
a "failure log" for the failed command. This log overwrites previous
|
|
logging. The default location is as follows:
|
|
|
|
* On Unix and Mac OS X: :file:`$HOME/.pip/pip.log`
|
|
* On Windows, the configuration file is: :file:`%HOME%\\pip\\pip.log`
|
|
|
|
The option for the failure log, is :ref:`--log-file <--log-file>`.
|
|
|
|
Both logs add a line per execution to specify the date and what pip executable wrote the log.
|
|
|
|
Like all pip options, ``--log`` and ``log-file``, can also be set as an environment
|
|
variable, or placed into the pip config file. See the :ref:`Configuration`
|
|
section.
|
|
|
|
.. _`exists-action`:
|
|
|
|
--exists-action option
|
|
======================
|
|
|
|
This option specifies default behavior when path already exists.
|
|
Possible cases: downloading files or checking out repositories for installation,
|
|
creating archives. If ``--exists-action`` is not defined, pip will prompt
|
|
when decision is needed.
|
|
|
|
*(s)witch*
|
|
Only relevant to VCS checkout. Attempt to switch the checkout
|
|
to the appropriate url and/or revision.
|
|
*(i)gnore*
|
|
Abort current operation (e.g. don't copy file, don't create archive,
|
|
don't modify a checkout).
|
|
*(w)ipe*
|
|
Delete the file or VCS checkout before trying to create, download, or checkout a new one.
|
|
*(b)ackup*
|
|
Rename the file or checkout to ``{name}{'.bak' * n}``, where n is some number
|
|
of ``.bak`` extensions, such that the file didn't exist at some point.
|
|
So the most recent backup will be the one with the largest number after ``.bak``.
