I was following this tutorial for aws-php sdk Tutorial.
I Installed composer manually by using Composer-Setup.exe.
So when I am trying to install composer by clicking composer.json>Composer>install
this error appeared.
And if you have some proper tutorial for using php-sdk, please comment it here.
The tutorial is 2years outdated.
What you are trying to do is execute composer.
The correct way to execute composer in a windows based system is:
php composer.phar install
or
c:\path\to\php php composer.phar install
The approach of using ./ works with linux based systems after you have made the file executable. You generally do not require that in windows.

I'm currently developing a web application (Django 2.0) application.
My app will be deployed on IBM Cloud (Cloud Foundry) using python build-pack.
One of my requirements is to install blender.
Everything else is very well, but for blender installation.
What I've tried so far was:
I tried access my app using SSH connection, but surely I don't have root access to apt-get install blender!!
And tried to include blender in packages.json file and push that file using cf push my-app.
But nothing worked for me.
In another shorter question: what is the main approach in Cloud Foundry Apps to install packages like when we use apt-get install in Ubuntu / Debian.
Please correct me if I did anything wrong, or guide me with headlines to solve this problem!!
I see a couple options for you to install packages if they cannot be installed using the regular requirements file (which is the preferred way):
Download the relevant libraries and put them in subfolders of the app before pushing it. The libraries will be uploaded. That is how I would do it.
Once you have an SSH connection, use secure copy (scp) to upload the files and place them in the subfolders where they are expected.
Regarding Blender, the question is what you need in addition to having the code copied over. Does it need a running daemon? Are there more dependencies? You would need to share more information about your specific app to answer that. Maybe, packaging everything as one or more containers and run it on Kubernetes or a combination of Cloud Foundry and Kubernetes is a better way.
I'm trying to install the commerce module in Drupal 8 however I get the error 'BC math PHP extension not found'.
I've searched for this problem and tried different things such as editing the PHP.ini by adding 'bcmath.scale=2' however I still get the error message.
Any help would be appreciated, thanks.
Just install bcmath plugin for your php version with no need to (re)build php as mentioned on accepted answer
# get php version
php -v
# install bcmath based on your version lets assume php 7.1
# for ubuntu
sudo apt install php7.1-bcmath
# for centos
yum install bcmath
# restart apache
sudo systemctl restart apache2
Above problem appears when installing commerce or commerce kickstart using composer
Update 2020
Please refer to #GiorgosK's answer for installing bcmath via a package manager if you are using a distribution that provides a bcmath package for PHP. I will ask the OP in comments to update the recommended answer, since that solution is probably what most people need.
Three years ago when I answered this question, I suggested that you have to rebuild PHP to get bcmath. That was incorrect. I was using an older distribution of Debian/Ubuntu that provided bcmath as a statically linked extension in the core php package. I determined at the time (incorrectly) that bcmath was a core extension that had to be enabled at build-time (like SPL and PCRE).
For those trying to troubleshoot a missing bcmath extension (such as those building/installing PHP themselves or nevertheless encountering issues), I've corrected and updated my original answer below. It explains in detail how to troubleshoot a missing PHP extension.
Original Answer (Corrected)
The error message indicates that PHP wasn't built with bcmath support or can't find the installed extension. PHP extensions are either built into PHP directly or they are loaded from an external dynamic library file at runtime.
Since PHP obviously doesn't have the extension built-in, it can't find the external library file that provides bcmath. This file on POSIX platforms will be called bcmath.so and php_bcmath.dll on Windows.
Extension files are installed under a directory indicated by the extension_dir property in php.ini. To determine the value of this property, run the following command:
php -r 'echo ini_get("extension_dir").PHP_EOL;'
The default value for this property is configured when PHP is built and may vary from distribution-to-distribution.
Once you verify the extension file is installed in this location, you can then check to see if the extension is enabled in php.ini. You should see a line that enables the extension like so:
# POSIX platforms
extension=bcmath.so
# Windows
extension=php_bcmath.dll
For Linux distributions like Ubuntu/Debian that install extensions via the package manager, the format is somewhat different since Debian employs a distributed configuration. Typically the package manager installs everything correctly, but you can check to see if an ini file exists for bcmath under the corresponding conf.d directory. These small ini files are snippets imported into the larger php.ini file, and they are typically symlinked to /etc/phpX/mods-available, allowing modules to be initially enabled for all PHP SAPIs such as CLI, CGI, Apache Mod PHP, ETC. Make sure a symlink exists for the PHP SAPI you need to use.
To ensure your PHP is loading the extension, run phpinfo(); in a test page and search for bcmath. You can also more easily do this with the CLI using a command like:
$ php -i | grep -i bcmath
# Success output: BCMath support => enabled
# (Another command that works well for checking extensions)
$ php -m | grep -i bcmath
# Success output: bcmath
In order for the CLI to show accurate results, it must target the same php.ini file. If it doesn't, then use the -c option to temporarily point the CLI at the correct php.ini (i.e. the one being used by your Drupal site).
Add BC MATH extension for PHP 7.2
If you are getting this (https://prnt.sc/sehmd5) error then, run below command using vagrant ssh
Run these command in root of vagrant ssh
sudo add-apt-repository ppa:ondrej/php
sudo apt update
sudo apt install php7.2-bcmath
service apache2 restart
Then open php.ini and search for bcmath
If bcmath scale is 0, Change it to 2
Restart php
Restart Apache
Hard Reload website
Install required modules
Similarly for any version of PHP, you only need to change PHP version in 3rd command.
I'm having trouble installing and configuring Leiningen on a Windows 7 work computer. I'm assuming that my company's firewall prevents the GitHub security certificate from authenticating.
I've tried to use the standalone jar but had trouble using it will several development tools Id like to use to work on Clojure projects.
What is the best way to get Leiningen set up given these circumstances? Is there a way to install curl or wget on Windows and call them from the batch file?
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
The error Im getting is:
Downloading Leiningen now...
'powershell' is not recognized as an internal or external command,
operable program or batch file.
Failed to download https://github.com/technomancy/leiningen/releases/download/2.
7.1/leiningen-2.7.1-standalone.zip
It is possible that the download failed due to "powershell",
"curl" or "wget"'s inability to retrieve GitHub's security certificate.
The suggestions below do not check certificates, so use this only if
you understand the security implications of not doing so.
The PowerShell failed to download the latest Leiningen version.
Try to use "curl" or "wget" to download Leiningen by setting up
the HTTP_CLIENT environment variable with one of the following
values:
a) set HTTP_CLIENT=wget --no-check-certificate -O
b) set HTTP_CLIENT=curl -f -L -k -o
NOTE: Make sure to not add double quotes when setting the value
of HTTP_CLIENT
Thanks!
I would suggest downloading and installing Git Bash (aka "Git for Windows), which includes not only Git but a nice linux-like environment (a leaner version of Cygwin). At that point you will avoid any Powershell-related problems, which your error msg seems to imply.

is there any well documented step by step procedure to install redmine?. I tried to install it on my Ubuntu machine.But i am unable to access it from another machine. please tell me how to it. is there any document which show how to host as centralized
See this guide: http://www.redmine.org/projects/redmine/wiki/redmineinstall. Its a general installation guide. I used it to install Redmine on Debian Jessie.
I'm a Windows user. I tried to install django-1.0.2 final through the command prompt and it kept giving me an error in line 70:
The error occured where u"SVN"... It couldn't get past that line.
What to do in order to be able to install django-1.0.2?
You do not have SubVersion installed on your machine. You are trying to synchronize from the current production stream via SubVersion, which is a source control system, which you do not have installed.
Easiest solution - download the latest official version per the instructions at http://www.djangoproject.com/download/
Please install a client for the Subversion Version Control System. Since you are on Windows, you can also use TortoiseSVN which is an easy to use SVN client for Windows.
Alternately, you can download the tarball of Django 1.0.2 directly.
And please don't SHOUT on Internet forums. We hear you :)
If I recall correctly, installing TortoiseSVN won't help you there cause Django's code tries to use SVN's command line version.
Install a command-line SVN like:
Slik SVN
CollabNet SVN Command line
What version of python are you using? I had the same error when installing on top of python 3.2 instead of 2.7. Django only works with 2.7.
