Hey everyone, giving up on trying to solve this one.
I have a Ubuntu server (not windows), and when trying to run a V8JS script and including lodash.min.js I am given this error: “The module ‘lodash’ could not be found in any known locations.”
Any ideas for what to do with this error in a Ubuntu instance?
Server: Ubuntu
DreamFactory: 2.0.1
//from Dreamfactory.log
production.DEBUG: * no “require()” support in V8 library v3.14.5.9
the same issue in debian jessie
local.DEBUG: * no “require()” support in V8 library v3.14.5.8
Admin Application Version: 2.1.3
DreamFactory Version: 2.1.0
when use the v8js post script sample
Regards
V8JS libraries are not prepackaged with DreamFactory. It is an add-on that you can install. These commands are what I use to get V8 on my setup (albeit old versions):
sudo apt-get install libv8-dev g++ cpp php5-dev
sudo pecl install v8js-0.1.3
sudo vi /etc/php5/mods-available/v8js.ini
Insert:
extension=v8js.so
sudo php5enmod v8js
//If apache.
sudo service apache2 restart
//If nginx
sudo service php5-fpm stop
sudo service nginx stop
sudo service php5-fpm start
sudo service nginx start
Good luck!
Thanks, sridharsa.
I thought I had done these steps but went through them once more to verify. v8js was enabled and installed, but I’m still receiving * no “require()” support in V8 library v3.14.5.9 in the logs (with no evidence of the v8js script firing).
same , for my v8js was enabled and installed and detected
but I’m still receiving * no “require()”
Hey everybody. In order to use require() you have to install version 0.3 or higher of v8js.
OKAY this is very helpful! Thanks to Drew’s point, I went out and attempted to install version 0.3+ of v8js.
Unfortunately, using pecl install on Ubuntu to install anything later than 0.1.3 results in an error message saying a newer version of libv8 needs to be installed. I struggled for a bit until I came upon this post:

Now the v8js error has gone away. Just a warning… the step “make native library=shared” took about 45 minutes for my Ubuntu server to compile.
EDIT: Don’t forget “sudo php5enmod v8js”
Hey,
Drew (Thank you!) wrote a detailed step by step process to compile and use the last supported version (0.4.1) for our PHP (v5.5) version. You can find that here: https://wiki.dreamfactory.com/DreamFactory/Installation/Modules/v8js
We will be migrating to PHP7 soon and then we can move to the latest V8JS (v1.1).
