I try to use appshot to take an image from a shiny app.
It works well on Windows, but not on my Debian server.
If I try this:
appdir <- system.file("examples", "01_hello", package = "shiny")
appshot(appdir, "01_hello.png")
this gives this:
(without the graph)
My server is Debian 11.5 with:
Shiny Server v1.5.18.987
Node.js v16.14.0
R version 4.2.1
phantomjs install like this : https://gist.github.com/julionc/7476620.
If anyone can help me.
Thanks a lot.
I install the 2.1.1 version of phantomjs.
Follow this https://gist.github.com/julionc/7476620 but replace 1.9.8 by 2.1.1.
It works !

When I tried to run this command:
c:\python27\scripts\pip install nltk-3.2.1-py2.py3-none-any
I am getting the error:
no matching distribution found
Although i have installed nltk from
http://www.lfd.uci.edu/~gohlke/pythonlibs/#nltk
Kindly help.
I am working on Windows 8 64-bit Version
Installing new modules can be a nightmare if you are new to Python.First delete any old versions of NLTK if already installed. Open cmd navigate to C:\Users\user\AppData\Local\Programs\Python\Python35-32\Scripts, the default directory, using the command cd path_name_comes_here. Otherwise goto the path where you have installed python and goto the Scripts subfolder and use this path here onwards. Now the most preferred way is to use pip install module_you_want_to_install for anything in python. Pip automatically fetches everything it needs to install said module.
Simply use pip install nltk.
Another method is to use easy_install requirement_or_URL.
Some rare occasions its best to download the wheel from http://www.lfd.uci.edu/~gohlke/pythonlibs and from there you can simply use pip install downloaded_wheel_name again. But make sure to copy the name of the wheel EXACTLY.
Post installation make sure that your package is accessible from C:\Users\user\AppData\Local\Programs\Python\Python35-32\Lib\site-packages or a similar path depending on where you installed python.
Try Anaconda - Instead . Always works

I'm reinstalling emacs24 on a remote server and can't seem to replicate my personal configuration and get it running.
I've installed the following pip packages using pip install --user (I don't have root on the server):
jedi, flake8, autopep8, rope, importmagic
Then I installed elpy using these lines in the .emacs config file:
;==============
; Use MELPA repository
(require 'package)
;; Any add to list for package-archives (to add marmalade or melpa) goes here
(add-to-list 'package-archives
'("MELPA" .
"http://melpa.milkbox.net/packages/"))
(package-initialize)
;==============
(require 'package)
(add-to-list 'package-archives
'("elpy" . "http://jorgenschaefer.github.io/packages/"))
Then I installed elpy from M-x package-list-packages and everything went well.
Everything is working except the in-buffer pep8 corrections.
My current elpy-config is:
Virtualenv........: None
RPC Python........: 2.7.6 (/usr/bin/python)
Interactive Python: ipython (/usr/local/bin/ipython)
Emacs.............: 24.3.1
Elpy..............: 1.10.0
Jedi..............: 0.9.0
Rope..............: 0.10.3
Importmagic.......: 0.1.3
Autopep8..........: 0.1.3
Syntax checker....: Not found (pyflakes)
Any ideas what I'm doing wrong?
I would love your help.
Thanks so much,
Shahar
Adding the following path to my .bashrc file (in my home dir) solved my problem.
export PATH=$PATH:~/.local/bin
Under this path elpy was able to find the missing package

Can you upgrade to Calabash Android 0.5.10.pre2?
This has solved the version for other users.
I downgraded to calabash-android 0.5.5 and it works like a charm now.
I am about to begin a project with Shiny (by RStudio). When I try to install the shiny package using the console install.packages("shiny"), I get the following error message:
trying URL 'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/shiny_0.10.1.tgz'
Warning in install.packages :
cannot open: HTTP status was '404 Not Found'
Error in download.file(url, destfile, method, mode = "wb", ...) :
cannot open URL'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/shiny_0.10.1.tgz'
Warning in install.packages :
download of package ‘shiny’ failed
I have tried to install it from the drop down menu in RStudio but have encountered the same problem. Any thoughts as to what is going on?
I am working on Mac, with the latest version of Mavericks (R version is 3.1.1).
Thanks,
Brian
Try a different CRAN mirror. The error indicates that the file was not found on the CRAN server
chooseCRANmirror()
shiny has just been updated 2014-10-01 so the changes may not have propagated down to all mirrors yet.
I just started going through railstutorial.org and getting my development environment setup. When I got to the section 1.2.5 to run rails server for the fist_app, I type the command and the following printed out:

When this first happened double checked the steps leading up to this in the tutorial, since being a beginner that was a high possibility. I typed the follow commands and everything checkout. (I'm also using OS 10.9.3)
$ rails -v
Rails 4.0.5
$ ruby -v
2.0.0p481
$ rvm -v
1.25.27
$ brew doctor
system ready to brew
Through searching some posts have suggested to uninstall sqlite3 and then re-install but I still got the same seg fault message. Not sure of the next step.
Your Rails -v and Ruby -v are correct for this tutorial.
I can also see from the input that your gemfile has gem 'sqlite3', '1.3.8' in it.
1: Have you bundled?
When was the last time you ran bundle update or bundle install?
How did you go about uninstalling sqlite3? Did you use $ gem uninstall sqlite3?
Try uninstalling and then reinstalling the gem.
2: - What version manager?
Did you use rvm, rbenv or homebrew to install? Using different version managers for different pieces can create communication issues.
3: Did you install Xcode?
This is taken from http://www.railstutorial.org:
"As a prerequisite, OS X users may need to install the Xcode developer tools. To avoid the (huge) full installation, I recommend the much smaller Command Line Tools for Xcode.
To install Xcode (my recommendation), look it up in the AppStore.
To install Command Line Tools (MHartl's recommendation) - https://developer.apple.com/downloads/
4: Are you using `bundle exec`?
Try bundle exec rails c and bundle exec rails s
5: Try 'refreshing' your bundle directory
If bundle exec doesn't work
Remove the .bundle/ directory and re-bundle with
rm -rf .bundle/ && bundle
I experienced the same issue, I just switched to a different ruby version
e.g;
rvm use 1.9.3-p484
and then bundle again.
