If `overwrite` is specified, matching files are purged before proceeding.

Parameters
|
|
----------
|
|
|
|
path : path to file, directory, zip or tarball archive, or URL to install
|
|
By default, the file will be installed with its base name, so '/path/to/foo'
|
|
will install to 'nbextensions/foo'. See the destination argument below to change this.
|
|
Archives (zip or tarballs) will be extracted into the nbextensions directory.
|
|
overwrite : bool [default: False]
|
|
If True, always install the files, regardless of what may already be installed.
|
|
symlink : bool [default: False]
|
|
If True, create a symlink in nbextensions, rather than copying files.
|
|
Not allowed with URLs or archives. Windows support for symlinks requires
|
|
Vista or above, Python 3, and a permission bit which only admin users
|
|
have by default, so don't rely on it.
|
|
user : bool [default: False]
|
|
Whether to install to the user's nbextensions directory.
|
|
Otherwise do a system-wide install (e.g. /usr/local/share/jupyter/nbextensions).
|
|
prefix : str [optional]
|
|
Specify install prefix, if it should differ from default (e.g. /usr/local).
|
|
Will install to ``<prefix>/share/jupyter/nbextensions``
|
|
nbextensions_dir : str [optional]
|
|
Specify absolute path of nbextensions directory explicitly.
|
|
destination : str [optional]
|
|
name the nbextension is installed to. For example, if destination is 'foo', then
|
|
the source file will be installed to 'nbextensions/foo', regardless of the source name.
