The base URL for the location of PhantomJS binaries for
download. If the default download site is unavailable, you may specify an
alternative mirror, such as
"https://bitbucket.org/ariya/phantomjs/downloads/".
Details
This function was designed primarily to help Windows users since it is
cumbersome to modify the PATH variable. Mac OS X users may install
PhantomJS via Homebrew. If you download the package from the PhantomJS
website instead, please make sure the executable can be found via the
PATH variable.
On Windows, the directory specified by the environment variable
APPDATA is used to store ‘phantomjs.exe’. On OS X, the directory
‘~/Library/Application Support’ is used. On other platforms (such as
Linux), the directory ‘~/bin’ is used. If these directories are not
writable, the directory ‘PhantomJS’ under the installation directory of
the webshot package will be tried. If this directory still fails, you
will have to install PhantomJS by yourself.
Value
NULL (the executable is written to a system directory).
