I am having a couple of problems packaging my Kivy app for android which may, or may not be related:
The only packages my app imports other than Kivy, are the time, and math modules. When I add either or both of them to the requirements in the buildozer spec file, I get a "pip._internal.exceptions.DistributionNotFound: No matching distribution for time." error. When I don't include them in my requirements, the build is successful, but crashes upon open with the error:
"Exception: The version of Kivy installed on this system is too old. (You have 1.11.1, but the application requires 2.0.0)"
I am doing the install in a VirutalBox on Ubuntu, and have followed the installation procedure outlined in the Kivy, and Buildozer documentation, as well as following a tutorial by Eric Sandberg on YouTube. I have set the Kivy version in the buildozer spec file, and installed Kivy 2.0.0 on the VM using pip. When I pip freeze, it shows the correct version of Kivy. One thing I have noticed is the when I try and install it with "apt-get install python3-kivy", it says kivy 1.10 is installed and that this is the most up to date version.
This seems like an easy problem to address but I have cannot figure out why it is trying to use this version of Kivy! Please let me know if any other information is required to debug. The spec file is hardly changed, other then specifying Kivy=2.0.0 in requirements.
Here are the logs:
Here are the requirements:
You don't have to add math and time in requirements of your buildozer.spec file as they are inbuild modules in python. So, they will automatically get added when you add python3 in your requirements.
To use a newer versio version of kivy you have to specify it in your requirements. In requirements you have to add like requirements=python3,kivy==2.0.0rc4 or any other version you want to use. Also, after changing requirements you might have to rebuild you package. You have to delete .buildozer directory and again run the buildozer using buildozer android debug deploy run

this error and warning is showing when I tried to install Kivy
As Python 3.10 is still currently relatively new and library developers need to recompile their package to the newest version, there is currently no way to install Kivy and its dependencies on Python 3.10 . I suggest you downgrade to Python 3.9 or even 3.8 for the installation to succeed.
Why can't I install this aqueduct?
Although I have installed dart before as shown in the picture:
It's important to ensure that the dart SDK is in the PATH. You can easily test it by trying to use pub or dart.
One way to ensure it's in the PATH is by creating a .bashrc file in your user's folder.
Then add the following:
export PATH="$PATH:/path/to/dart/installation/bin/folder"
First of all check if dart is installed using dart --version if it gives a command not found error that means it is not installed (hence why you cannot install aqueduct since it requires pub which is shipped with the dart sdk).
To install dart on macOS first install brew and the follow the instruction here https://dart.dev/get-dart (don't run brew switch dart 2.1.0 as shown in the screenshot since it makes no sense because current the latest stable is 2.9.1 and 2.1.0 is pretty old).
If you don't want to install brew you can download the sdk here (for your system) extract it, and update your path variable as #gabriel-octávio says.
Someone has asked the exact question I need on this page.
However, as I am new, my rep will not allow me to comment yet! So I have had to create a new question.
A guy in the question linked above suggests to "Type cordova platform add ios;". So there I suppose is where my question is different.
When I type Cordova in cmd prompt, I get a message saying "cordova is not recognized as an internal or external command, operable program or batch file."
Update: Please note, I have followed these steps: http://cordova.apache.org/docs/en/7.x/guide/cli/ And I am able to run the npm commands in CLI. I was hoping to simply update my ios version only.
I have also looked up PATH but I have no idea where to start, problem is, people suggest that I shouldn't need to adjust PATH as running the CLI commands to install the Cordova CLI should just allow me to use it?
So to summarize:
I downloaded the node.js and installed it
I typed this into cmd "npm install -g cordova" which installed
I type "cordova" and get my "cordova is not recognized as an internal or external command" message above
My aim is to upgrade my cordova-ios 4.2.0 to cordova-ios 4.3.0 to fix my main error of "remote build requires your projects to use cordova-ios 4.3.0 or greater with XCode 8.3"
Update 2 9th oct 2017:
I have given up for now with the above, to work around this i installed Node.js 8.6.0 then updated cordova using npm... im now facing some more issues that I am again stuck on and will create a new question.
Hopefully in the meantime, someone can answer this question and i can try again.
I suspect my issues could be relating to the fact i installed VS 2017 and used all the built in nuget packages (for cordova and node.js) and they are conflicting with the manual way in some way (i suspect that, as running the "cordova" command on my other PC worked fine!)
We recently decided to use Android Studio's CMake support as a part of our development, and as far as compiling and building is concerned everything works fine for the development team.
As a part of our validation efforts we are also running Jenkins for continuous testing, and that's where the problems are starting. The machine running Jenkins does not have Android Studio installed, nor it has an UI. As such it only possesses the android NDK and SDK. However, when running tests, the following error occurs :
Failed to find CMake.
Install from Android Studio under File/Settings/Appearance & Behavior/System Settings/Android SDK/SDK Tools/CMake.
Expected CMake executable at /home/vagrant/android-sdk-linux/cmake/bin/cmake.
The problem now is that there is no way to install CMake like suggested ! The machine does not have any UI to run Android Studio, and the command line tools feature no option to install CMake. And creating sym-links isn't the solution either, as CMake isn't the only thing it's looking for.
How am I supposed to make my project work on the machine ? CMake is running perfectly (as it was already used as part of the tests) so the problem is only coming from Gradle looking only in the SDK directory for it...
The problem now is that there is no way to install CMake like suggested
Actually it is not! Instead of using android list sdk command for installing sdk packages you should use new command line tool: sdk-manager.
Ndk, cmake are available for installing through this new android sdk tool.
you need to install manually cmake on your system unix:
go to your android sdk directory ${ANDROID_HOME} and create new cmake folder with:
wget "https://dl.google.com/android/repository/cmake-3.6.3155560-linux-x86_64.zip"
unzip -q cmake-3.6.3155560-linux-x86_64.zip -d ${ANDROID_HOME}/cmake
add to PATH ENV ${PATH}:${ANDROID_HOME}/cmake/bin
I'm trying to use luagraph, a binding to the graphviz library:
http://luagraph.luaforge.net/index.html
To install, I'm using luarocks in Mac OS X. The following command is executed in bash:
luarocks install luagraph
The output is the following:
Installing https://luarocks.org/luagraph-1.0.4-1.src.rock... Using
https://luarocks.org/luagraph-1.0.4-1.src.rock... switching to 'build'

Error: Could not find expected file graphviz/graph.h, or
graphviz/graph.h for GRAPHVIZ -- you may have to install GRAPHVIZ in
your system and/or pass GRAPHVIZ_DIR or GRAPHVIZ_INCDIR to the
luarocks command. Example: luarocks install luagraph
GRAPHVIZ_DIR=/usr/local
I have been installed graphviz using homebrew, but I can't figure out how to pass GRAPHVIZ_DIR or GRAPHVIZ_INCDIR properly.
How can I install luagraph?
I've updated LuaGRAPH a couple of weeks ago. It now supports the newest version of Graphviz based on the cgraph library instead of the old graph library.
There is one drawback: I couldn't get luagraph to run on Windows using mingw because of some runtime library issues (compiler and dll compatibility probably). Please look at the README file for more details.
I personally never produced a rockspec for this module. This was created by someone else based on a fork of my luagraph library.
Installation without Luarocks is simple. Download from
https://github.com/hleuwer/luagraph
and follow the instruction in the documentation and the README file. You need adopt a simple config file which is included by make.

Well, luaGRAPH is still the top result when searching for lua and graph. So the question is still standing.
And, unfortunately, the answer is: luagraph is OLD, the last update happened before the ubuntu 14.04 was released. And there seem to be some notable changes in the system itself, the flags the error message show do not seem to work. On top of that, graphviz is now about 20 releases newer than the luarock recommends.
There now is a bare bone alternative lua package: graphviz
It is extremely basic, and documentation in not at all informative, but at least it works.
update: Luagraph may be working again, but not through rocks. See the other answer.
