\arguments{
\item{envname}{The name of, or path to, a Python virtual environment. If
this name contains any slashes, the name will be interpreted as a path;
if the name does not contain slashes, it will be treated as a virtual
environment within \code{virtualenv_root()}. When \code{NULL}, the virtual environment
as specified by the \code{RETICULATE_PYTHON_ENV} environment variable will be
used instead.}

\item{python}{The path to a Python interpreter, to be used with the created
virtual environment. When \code{NULL}, the Python interpreter associated with
the current session will be used.}

\item{packages}{A character vector with package names to install or remove.}

\item{ignore_installed}{Boolean; ignore previously-installed versions of the
requested packages? (This should normally be \code{TRUE}, so that pre-installed
packages available in the site libraries are ignored and hence packages
are installed into the virtual environment.)}

\item{pip_options}{An optional character vector of additional command line
arguments to be passed to \code{pip}.}

\item{...}{Optional arguments; currently ignored for future expansion.}

\item{confirm}{Boolean; confirm before removing packages or virtual
environments?}

\details{
Virtual environments are by default located at \verb{~/.virtualenvs} (accessed
with the \code{virtualenv_root} function). You can change the default location by
defining defining the \code{WORKON_HOME} environment variable.

Virtual environment functions are not supported on Windows (the use of
\link[=conda-tools]{conda environments} is recommended on Windows).
