Package renamed to phantomjs-prebuilt. Please update 'phantomjs' package references to 'phantomjs-prebuilt'
An NPM installer for PhantomJS, headless webkit with JS API.
Please update your package references from
Building and Installing
npm install phantomjs
Or grab the source and
What this installer is really doing is just grabbing a particular "blessed" (by this module) version of Phantom. As new versions of Phantom are released and vetted, this module will be updated accordingly.

And npm will install a link to the binary in

Running via node
The package exports a
path string that contains the path to the
Below is an example of using this package via node.
var path =var childProcess =var phantomjs =var binPath = phantomjspathvar childArgs =path'some other argument (passed to phantomjs script)'childProcess
The major and minor number tracks the version of PhantomJS that will be installed. The patch number is incremented when there is either an installer update or a patch build of the phantom binary.
Deciding Where To Get PhantomJS
By default, this package will download phantomjs from our releases. This should work fine for most people.
Downloading from a custom URL
If github is down, or the Great Firewall is blocking github, you may need to use
a different download mirror. To set a mirror, set npm config property
https://bitbucket.org/ariya/phantomjs/downloads (the official download site)
npm install phantomjs --phantomjs_cdnurl=
Or add property into your
.npmrc file (https://www.npmjs.org/doc/files/npmrc.html)
Another option is to use PATH variable
PHANTOMJS_CDNURL=https://bitbucket.org/ariya/phantomjs/downloads npm install phantomjs
Using PhantomJS from disk
If you plan to install phantomjs many times on a single machine, you can
phantomjs binary on PATH. The installer will automatically detect
and use that for non-global installs.
PhantomJS needs to be compiled separately for each platform. This installer finds a prebuilt binary for your operating system, and downloads it.
If you check your dependencies into git, and work on a cross-platform team, then you need to tell NPM to rebuild any platform-specific dependencies. Run
as part of your build process. This problem is not specific to PhantomJS, and this solution will work for any NodeJS package with native or platform-specific code.
If you know in advance that you want to install PhantomJS for a specific architecture,
you can set the environment variables:
(to set target platform) and
PHANTOMJS_ARCH (to set target
arch are valid values for
process.platform and process.arch.
A Note on PhantomJS
PhantomJS is not a library for NodeJS. It's a separate environment and code written for node is unlikely to be compatible. In particular PhantomJS does not expose a Common JS package loader.
This is an NPM wrapper and can be used to conveniently make Phantom available It is not a Node JS wrapper.
I have had reasonable experiences writing standalone Phantom scripts which I then drive from within a node program by spawning phantom in a child process.

An extra note on Linux usage, from the PhantomJS download page:
There is no requirement to install Qt, WebKit, or any other libraries. It however still relies on Fontconfig (the package fontconfig or libfontconfig, depending on the distribution).
Installation fails with
This is NPM's way of telling you that it was not able to start a process. It usually means:
nodeis not on your PATH, or otherwise not correctly installed.
taris not on your PATH. This package expects
taron your PATH on Linux-based platforms.
Check your specific error message for more information.
Installation fails with
Error: EPERM or
operation not permitted or
This error means that NPM was not able to install phantomjs to the file system. There are three major reasons why this could happen:
- You don't have write access to the installation directory.
- The permissions in the NPM cache got messed up, and you need to run
npm cache cleanto fix them.
- You have over-zealous anti-virus software installed, and it's blocking file system writes.
Installation fails with
Error: read ECONNRESET or
Error: connect ETIMEDOUT
This error means that something went wrong with your internet connection, and the installer was not able to download the PhantomJS binary for your platform. Please try again.
I tried again, but I get
Do you live in China, or a country with an authoritarian government? We've seen problems where the GFW or local ISP blocks github, preventing the installer from downloading the binary.
Try visiting the download page manually.
If that page is blocked, you can try using a different CDN with the
env variable described above.
I am behind a corporate proxy that uses self-signed SSL certificates to intercept encrypted traffic.
You can tell NPM and the PhantomJS installer to skip validation of ssl keys with NPM's strict-ssl setting:
npm set strict-ssl false
WARNING: Turning off
strict-ssl leaves you vulnerable to attackers reading
your encrypted traffic, so run this at your own risk!
I tried everything, but my network is b0rked. What do I do?
If you install PhantomJS manually, and put it on PATH, the installer will try to use the manually-installed binaries.
I'm on Debian or Ubuntu, and the installer failed because it couldn't find
Some Linux distros tried to rename
nodejs due to a package
conflict. This is a non-portable change, and we do not try to support this. The
recommends that you run
apt-get install nodejs-legacy to symlink
on those platforms, or many NodeJS programs won't work properly.
Questions, comments, bug reports, and pull requests are all welcome. Submit them at the project on GitHub. If you haven't contributed to an Medium project before please head over to the Open Source Project and fill out an OCLA (it should be pretty painless).
Bug reports that include steps-to-reproduce (including code) are the best. Even better, make them in the form of pull requests.
