I am trying to parse the rdf file but
I am getting error while executing following code in ubuntu
RDF::Reader.open("http://datagraph.org/jhacker/foaf.rdf") do |reader|
reader.each_statement do |statement|
puts statement.inspect
end
end
as
LoadError: Could not open library 'libraptor': libraptor: cannot open shared object file: No such file or directory. Could not open library 'libraptor.so': libraptor.so: cannot open shared object file: No such file or directory
I installed all the required gems:
rdf
rdf-raptor
ffi
rdf-json
rdf-trix
Please help me how to rectify this problem
I suggest you visit http://rdf.rubyforge.org/raptor/ and use the contact info mentioned there such as the mailing list. The error is because the C shared library libraptor.so cannot be found by ruby, so it must have been installed in a non-standard place. I am the author of Raptor but I do not know how rdf-raptor installed Raptor.

I recently updated R and Rstudio and since then have not been able to load any libraries, including ggplot2, tidyverse.
Just for clarity, let me share the messages I get when I install tidyverse and try to load the library:
install.packages("tidyverse")
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:
**https://cran.rstudio.com/bin/windows/Rtools/

unable to load shared object 'C:/Program Files/R/R-4.2.2/library/stats/libs/x64/stats.dll':
LoadLibrary failure: The specified module could not be found.
**
Also, to be clear, I did install the latest version of Rtools.
Now I tried reading through several messages on google regarding the same error but failed to understand the solution. The main thing I do not understand is why the packages are installed here: C:\Users\Computer User 1\AppData\Local\Temp\RtmpQZdI11\downloaded_packages, and then are loaded from here: C:/Program Files/R/R-4.2.2/library/stats/libs/x64/stats.dll.
I have tried specifying the library path but have not been successful at solving the problem. I don't know why R is unable to load the libraries. Also, on running .libpaths(), I get two libraries:
[1] "C:/Users/Computer User 1/AppData/Local/R/win-library/4.2"
[2] "C:/Program Files/R/R-4.2.2/library"
And when I try to install tidyverse here: C:/Program Files/R/R-4.2.2/library, I get this error: the folder is unwritable.
I don't know how to solve this issue. Please help.
I have recently updated to Apache 2.4, and I am using Ruby on Rail to run my application. Following the upgrade, the site shows a content as seen in the image below, and the error on the log file shows this error message. I have tried using the 'Bundle Install' and checked the permission but that hasn't helped. Any advice would be greatly appreciated. Thanks

Message from application: libmysqlclient.so.18: cannot open shared object file: No such file or directory - /usr/local/rvm/gems/ruby-2.0.0-p353#hroot/gems/mysql2-0.3.14/lib/mysql2/mysql2.so (LoadError)
PassengerRuby /usr/local/rvm/gems/ruby-2.0.0-p353#hroot/wrappers/ruby
SetEnv GEM_HOME /root/.gem/ruby/1.9.1
This error shows a problem with the shared objects. You probably updated MySQL/MariaDB libraries with Apache and new libraries are incompatible with your mysql2 gem build. The solution is simple:
First, ensure you are using the ruby-2.0.0-p353#hroot RVM environment.
Then, execute the following command:
gem install mysql2 --version 0.3.14
This should rebuild your mysql2 gem for the new MySQL/MariaDB client libraries on your system.
this isn't the answer anyway but another method to run ruby (in my case Windows 10 ; if you use another OS try to find out how to modify inside index.php the ruby starter)
i post here an alternative method to use apache + php +... and ruby

I am new to esp32 programming. I wanted to try to make a server.
I tried to use the ESPAsyncWebServer library.
I got this error
In file included from C:\Users\User\Documents\Arduino\server\server.ino:2:0:
Multiple libraries were found for "WiFi.h"
sketch\ESPAsyncWebServer.h:33:22: fatal error: AsyncTCP.h: No such file or directory

Error compiling for board ESP32 Wrover Module.
Can someone help me and tell me what is the correct way to install liberals because I have a feeling that I am doing it wrong.
Your compile error says that you are lacking the AsyncTCP library. You can find it here: https://github.com/me-no-dev/AsyncTCP
You will need to install both libraries ESPAsyncTCP and ESPAsyncWebServer, since the latter is dependant on the first.
You can install them by:
Downloading the zip files from github:
https://github.com/me-no-dev/ESPAsyncWebServer
https://github.com/me-no-dev/ESPAsyncTCP
In your Arduino IDE go to Sketch > Include Library > ZIP-Library and select the libraries you just downloaded.
I am trying to create an exe of my Python application using py2exe. I am getting this error: "Import error: No module named linecache"
I've tried everything that has been suggested on this forum in the past, but nothing works. Please help.
indeed it takes days trying to install cinelerra and no longer know what else to do eh searched forums and I have sent emails to the list of cinelerra still can not solve anything thanks in advance
just interested in using cinelerra I have slackware 13.37 Download the TXZ of
http://repository.slacky.eu/slackware-13.37/multimedia/cinelerra/20110512/cinelerra-20110512-i486-1sl.txz
says that it installs correctly put:
# cinelerra
and I get the following error:
cinelerra: error while loading shared libraries: libavcodec.so.52: cannot open shared object file: No such file or directory
Download ffmpeg-0.7 from slacky.eu and install it. This will solve problem with missing libavcodec.so.52
