follow Sinatra write extension document, I write a ./lib/sinatra/test_helper.rb file containing my TestHelper, but using rackup start I got this error:
/...PATH.../vendor/cache/ruby/1.9.1/gems/backports-3.1.1/lib/backports/tools.rb:328:in `require': cannot load such file -- sinatra/testhelper (LoadError)
Seems Bundler could find my custom helpers extension. How to declare it in my Gemfile?

The current documentation says, that I only need the files under public/build, created with ./node_modules/.bin/encore production, when I want to deploy for production. But also to add public/build to git ignore. Do I have to copy the content of public/build manually?
In Symfony3 my deploy looked like that:
git pull
bin/php bin/console cache:clear --env=prod --no-debug
bin/php bin/console assets:install --env=prod
bin/php bin/console assetic:dump --env=prod --no-debug
FYI, Using assetic was the »old« way, and starting Symfony 2.8 Assetic is not included in the standard framework anymore (but you can still add it).
Regarding public/build you misunderstood it a bit - the actual source files should be somewhere else, for example in assets/css/app.scss and assets/js/app.js. Using Webpack Encore, running ./node_modules/.bin/encore production will minify, uglify, etc (whatever you configure in webpack.config.js) these source files and then copy the generated files to public/build. So public/build will only contain the generated stuff and thus can be safely added to .gitignore (but you also need to run the encore script in production).
Your JavaScript file (i.e. in this case app.js) should include
require('../css/app.scss');
so that the app.scss is actually a dependency of app.js and you only need to tell the webpack.config.js to include the JavaScript file. The basic configuration of webpack.config.js might look like this:
// webpack.config.js
var Encore = require('#symfony/webpack-encore');
Encore
// this will put all your compiled stuff into public/build, that’s
// why you can put this into .gitignore, because you can re-build this
// from the source files.
.setOutputPath('public/build/')
// the public path used by the web server to access the previous directory
.setPublicPath('/build')
// this will create public/build/app.js, and also public/build/app.css
// since the scss file is a dependency of app.js
.addEntry('app', './assets/js/app.js')
// allow sass/scss files to be processed
.enableSassLoader()
[...]
;
// export the final configuration
module.exports = Encore.getWebpackConfig();
You can find some more explanation under https://symfony.com/doc/current/frontend/encore/simple-example.html (first example) or https://symfony.com/doc/current/frontend.html (overview)
I can run my scrapy locally without any issues, however, when i try to run job from scrapinghub i get the following error (connecting to mongo atlas cloud):
exceptions.ImportError: No module named pymodm
I import using:
import pymodm
Any help is much appreciated.
Cheers
Create a file named scrapinghub.yml in your project's main folder with following contents.
projects:
default: 111149
requirements:
file: requirements.txt
Where 111149 is my proejct ID on scrapinghub.
Create another file named requirements.txt in same directory.
and put your required modules along with the version number you are using in that file like so,
MySQL-python==1.2.5
PS: I was using MySQLDB module so I put that.
I have a local javascript in my application that i want to include in my ember-cli application.
it is called carrotsearch.foamtree.js
In order that it will be included i put it under vendor\foamtree\carrotsearch.foamtree
and in the app.js i write
import CarrotSearchFoamTree from 'foamtree/carrotsearch.foamtree'
the problem is that i get an error

I thought that the problem is maybe bower related so i followed the following post how to include a private local file in javascript project using bower
The problem is that neither
"foamtree": "foamtree/carrotsearch.foamtree.js"
nor
"foamtree": "vendor/foamtree/carrotsearch.foamtree.js"
works.
What may i do?
Thanks,
David
I found an answer.
In brocfile.js we can add the line
app.import('vendor/foamtree/carrotsearch.foamtree.js')
I don't know if this is an optimal anser but it works
Update:
This solution is stated in the ember-cli documentation
http://iamstef.net/ember-cli/#managing-dependencies
If you don't need them to minified in your vendor.js file you can put them in the public/js and then include it as a normal script file in app/index.html. I use this method for some libraries like moment.js.
The public folder gets directly copied to your site root during the build.
I have a whole bunch of working C++ code that I want to write Python bindings for. I'm trying to use Boost.Python since it seems to be the easiest way to get this working, but it isn't cooperating. Here's part of the code for the extension module I'm trying to build:
BOOST_PYTHON_MODULE(libpcap_ext) {
using namespace boost::python;
class_<PacketEngine>("PacketEngine")
.def("getAvailableDevices", &PacketEngine_getAvailableDevices);
}
Bjam seems to be a pain and refuses to recognize my Pythonpath or allow me to link with libpcap, so I'm using CMake. Here's my CMakeLists file, which can import and build everything just fine (outputs libpcap.so as expected):
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
IF(NOT CMAKE_BUILD_TYPE)
SET(CMAKE_BUILD_TYPE "DEBUG")
#SET(CMAKE_BUILD_TYPE "RELEASE")
#SET(CMAKE_BUILD_TYPE "RELWITHDEBINFO")
#SET(CMAKE_BUILD_TYPE "MINSIZEREL")
ENDIF()
FIND_PACKAGE(Boost 1.55.0)
find_package(PythonLibs REQUIRED)
IF(Boost_FOUND)
INCLUDE_DIRECTORIES("${Boost_INCLUDE_DIRS}" "${PYTHON_INCLUDE_DIRS}")
SET(Boost_USE_STATIC_LIBS OFF)
SET(Boost_USE_MULTITHREADED ON)
SET(Boost_USE_STATIC_RUNTIME OFF)
FIND_PACKAGE(Boost 1.55.0 COMPONENTS python)
ADD_LIBRARY(pcap_ext MODULE PacketWarrior/pcap_ext.cc PacketWarrior/PacketEngine.h PacketWarrior/PacketEngine.cc PacketWarrior/Packet.h PacketWarrior/Packet.cc)
TARGET_LINK_LIBRARIES(pcap_ext pcap)
TARGET_LINK_LIBRARIES(pcap_ext ${Boost_LIBRARIES} ${PYTHON_LIBRARIES})
ELSEIF(NOT Boost_FOUND)
MESSAGE(FATAL_ERROR "Unable to find correct Boost version. Did you set BOOST_ROOT?")
ENDIF()
ADD_DEFINITIONS("-Wall")
And my pcap.py file that attempts to utilize the module:
import libpcap_ext
engine = libpcap_ext.PacketEngine()
print engine.getAvailableDevices()
But whenever I try to run the module, I get the following error:
Traceback (most recent call last):
File "../pcap.py", line 2, in <module>
engine = libpcap_ext.PacketEngine()
TypeError: __init__() should return None, not 'NoneType
I'm assuming it's because Boost.Python is trying to use Python 3 and my system default is Python 2.7.3. I've tried changing my user-config.jam file (in my boost_1_55_0 directory) to point to Python 2.7 and tried building:
# Configure specific Python version.
# using python : 2.7 : /usr/bin/python2.7 : /usr/include/python2.7 : /usr/lib ;
Boost.Python's installation instructions [0] seem to fail for me when I try to build quickstart with bjam (lots of warnings), so I tried following the Boost Getting Started instructions [1] to build a Python header binary, which is I think what is causing this problem. Any recommendations as to how to fix this would be amazing, I've spent hours on this.
This error is probably due to linking against the wrong Python library. Make sure your extension as well as the Boost Python library are linked against the Python installation you are using to import the module.
On Linux you can check against which libraries you've linked with ldd. On OS X otool -L does the same thing. So, for example
otool -L libpcap_ext.so
otool -L /path/to/libboost_python-mt.dylib
should list the Python library they are linked against.
With CMake you can use the variable PYTHON_LIBRARY to change which Python library is used. As an example, on the command line you can set it with
cmake -DPYTHON_LIBRARY="/path/to/libpython2.7.dylib" source_dir
Lastly, on OS X a quick and dirty way (i.e. without recompiling) to change the dynamically linked libraries is install_name_tool -change.
we are using PDFlib for personalizing PDFs.
The pdflib.jar library and the libpdf_java.so file are both in the folder:
/home/user/my/custom/library/path/
I start the server with this argument:
java -Djava.library.path=/home/user/my/custom/library/path/
like it is mentioned in the pdflib tutorial
After deploying on my jBoss5 Server i got this error message:
ERROR [STDERR] Cannot load the PDFlib shared library/DLL for Java.
Make sure to properly install the native PDFlib library. For your
information, the current value of java.library.path is:
/home/user/my/custom/library/path/
So, the path ist correct (i tried it with and without the / at the end)
If I put the jar and the lib in my /usr/lib folder, everything works fine, but not with my custom folders.
I use it on a linux 64bit, if that matters!
The custom folder and the files got chmod 755 - so this shouldn't be the problem
Looking forward to your hints!
