python -m pip <command> [options]
py -m pip <command> [options]
pip offers -v, --verbose and -q, --quiet to control the console log level. By default, some messages (error and warnings) are colored in the terminal. If you want to suppress the colored output use --no-color .
pip offers the --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.
Like all pip options,
--log
can also be set as an environment variable, or placed into the pip config file. See the
配置
章节。
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.
Only relevant to VCS checkout. Attempt to switch the checkout to the appropriate URL and/or revision.
Abort current operation (e.g. don’t copy file, don’t create archive, don’t modify a checkout).
Delete the file or VCS checkout before trying to create, download, or checkout a new one.
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
.
Abort pip and return non-zero exit status.
This is now covered in 构建系统接口 .
