Composer & Cygwin - cygwin

Question

Composer doesn't run correctly in Cygwin if you try to install it "globally".
Putting composer.phar into /usr/local/bin/composer, then trying to run it will result in the error:
Could not open input file: /usr/local/bin/composer

Answer 1

Just tripped over the same problem and found a solution. Posting it here, just in case I'll ever have to look it up again.
Set up a bin directory right under /home/my-username:
cd ~
mkdir bin
Move the composer.phar (or any other of those nifty new PHP imps that are on the rise)
into the ~/bindirectory and make sure to set it's execution bit:
# Notice how I got rid of the superfluous `.phar` extension
mv /path/to/composer.phar ~/bin/composer
chmod +x ~/bin/composer
Tell cygwin to include your ~/bin directory in the search path:
Open up the file ~/.bash_profile and uncomment the following paragraph ...
# Set PATH so it includes user's private bin if it exists
if [ -d "${HOME}/bin" ] ; then
PATH="${HOME}/bin:${PATH}"
fi
Now, for the most important part:
A wrapper script that helps Win's native PHP resolve Unix style paths (which is causing
the problem after all as Windows doesn't know how to handle /cygdrive/... paths).
cd ~/bin
touch php
chmod +x php
After editing the wrapper script ~/bin/php should read:
#!/bin/bash
# e.g. php="/cygdrive/c/Program Files (x86)/php/php.exe"
php="/path/to/php.exe"
for ((n=1; n <= $#; n++)); do
if [ -e "${!n}" ]; then
# Converts Unix style paths to Windows equivalents
path="$(cygpath --mixed ${!n} | xargs)"
case 1 in
$(( n == 1 )) )
set -- "$path" "${#:$(($n+1))}";;
$(( n < $# )) )
set -- "${#:1:$((n-1))}" "$path" ${#:$((n+1)):$#};;
*)
set -- "${#:1:$(($#-1))}" "$path";;
esac
fi
done
"$php" "$#"
Now restart your shell and it should correctly invoke the PHP interpreter whenever it
stumbles upon a #!/usr/bin/env php shebang. Simply issue a:
composer --help

How about this one?
In ~/.bashrc, add: alias composer='php c:\\your\\path\\to\\composer.phar'
Restart cygwin or reload the bashrc by running source ~/.bashrc
Works for me using both Cygwin's native php.exe and XAMPP's Windows-specific one.

Answer 3

I think what might work is to build a proxy instead:
Put composer.phar in /usr/local/bin/composer.phar
Create a bash proxy as /usr/local/bin/composer with the following:
#!/bin/sh
c:/path/to/php c:/path/to/composer.phar $#
chmod +x /usr/local/bin/composer

Try this:
Install Cygwin PHP and use it to run composer in Cygwin.
You can choose one of two ways to work fine with PHP+Composer in Cygwin:
Install Cygwin PHP and install composer.phar in Cygwin.
Install Windows PHP and install Winodows Composer, then call then from Cygwin. (Windows XAMMP+Composer with alias in cmd)
Your problem is caused by that Cygwin Composer is ruining by Windows PHP on Cygwin, so it can not recognize the file path.
After install Cygwin PHP, the composer will integrates with Cygwin PHP then fit to Cygwin's filepath.
Cygwin PHP extensions for composer usage:
php
php-json
php-mbstring
php-phar
php-zip
php-posix
You can install other PHP extension when composer's package is needed such as php-xmlwriter, php-tokenizer, php-ctype.
Installation commands guide:
If you have already installed apt-cyg, there are installation command above:
apt-cyg install php php-json php-mbstring php-phar php-zip php-posix
apt-cyg install php-xmlwriter php-tokenizer php-ctype
Then install Composer via Cygwin PHP:
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
php -r "unlink('composer-setup.php');"
chmod +x ./composer.phar
mv ./composer.phar /usr/bin/composer
composer -v
Conclusion
I recommend using Windows PHP + Windows Composer, and call then in Cygwin, it because the Cygwin PHP is not much stable than Windows PHP.

Answer 5

I had the same problem. After reading the final instruction from composer installer, it says that the $PATH variable should be reloaded. I rebooted my computer and then linked the Composer bin to /usr/local/bin.
First locate the composer bin :
/cygdrive/c/ProgramData/ComposerSetup/bin/composer
Then according to Seldaek answer, after trying a non-working symlink, I did :
nano /usr/local/bin/composer
#!/bin/sh
/cygdrive/c/ProgramData/ComposerSetup/bin/composer $#
chmod +x /usr/local/bin/composer
And it's working.

Answer 6

What I did (very simple):
Install Composer normally with the Windows installer
Open a Cygwin console an type composer you will see something like Could not open input file: /c/route/to/your/composer/installation/bin
Create an alias composer='composer.bat' on your bash profile or bashrc or whatever
Done
I'm running Windows 8.1

Answer 7

I was having this issue. Most of the responses were over my head but I fixed it with no problems.
Step 1) Reinstall Composer globally as per https://getcomposer.org/download/
Step 2) Leave it alone. All the special stuff you want to do, don't do that.
Step 3) Download the latest setup-xxx.exe from https://cygwin.com/
Step 4) Click it with your mouse.
NOTE: During step 5 you will feel a sudden urge to read instructions, browse the web for info and start checking little boxes on the menu. Don't do that.
Step 5) Click 'next' until it stops asking. It will look at your existing
settings, fix things up and add any missing dependencies.
This worked for me.

Answer 8

Getting composer to work globally inside Cygwin is a pain in the butt...
The solutions I have come up with:
Don't use it globally. If you are using the PHP CLI from a Windows installation, it won't recognize the Linux paths that Cygwin uses.
What I have done is put it in the base directory of all the projects I use composer with, and do ../composer.phar to run it.
It works fine this way, and it's almost globally available...
Download, and compile your own PHP binaries within Cygwin... Yea, kind of a overkill.

Answer 9

I solved the problem like this in a Cygwin/XAMPP setup:
Install composer.phar to XAMPP's php directory
Create an executable Bash script named composer in XAMPP's php directory:
#!/bin/bash
script_dir=$(cygpath -w $(dirname $0))
php "$script_dir/composer.phar" $#
It's important to use cygpath -w to convert the path to a path in Windows form.
Make sure XAMPP's php directory is accessible in Cygwin's $PATH:
$ export PATH=$PATH:/cygdrive/i/dev/server/xampp/php
Now it's possible to call composer from anywhere you like without problems:
$ composer -V
Composer version 264f433ca3f007d39568b3722b4bf418f58ba15b

Answer 10

I fixed it by adding a /usr/local/bin/composer file:
nano /usr/local/bin/composer
with the following content:
#!/bin/bash
/cygdrive/c/wamp/bin/php/php5.4.3/php "C:\wamp\bin\php\php5.4.3\composer"
Basically, you have to call PHP with a Windows style path, not a cygwin path.

Answer 11

The easiest way is to install composer using the Windows installer from their website and then copy the two files 'composer' and 'composer.phar' from "C:\ProgramData\Composer" into a directory which is in the PATH variable. E.g. you could copy the files into the /bin/ directory of cygwin. Afterwards you can again uninstall the "Windows version" of composer.
Update! This is what I did:
Install PHP and needed modules from the Cygwin Ports project
Download the latest composer snapshot
Rename 'composer.phar' to 'composer' and save it to /usr/local/bin
Open /bin/dash.exe and run '/usr/bin/rebaseall'
Also if 4. gives you an error, composer should run now

Answer 12

I suggest you use babun, it is based cygwin, but you can install package by pact, you can do this:
pact install php php-json php-phar
php -r "readfile('https://getcomposer.org/installer');" | php
then enjoy yourself.

Answer 13

I was having trouble getting Composer to work in Cygwin and none of the solutions above were resolving my problem. Eventually I stumbled across this comment in the Composer github bugs discussion:
Yeah TBH using php from cygwin isn't a great idea, cygwin is just too different an environment. Too many hacks that create failures.. In any case closing here as there isn't much we can do I'm afraid :)
I don't know precisely where composer/Cygwin/php was tripping up, but, broadly, my problem was that I had two conflicting installations of PHP in environmental variables, one from an installation of WAMP, and another installed with Cygwin. The Cygwin PHP installation seemed to be struggling with some sort of path issue. I removed it, using only the WAMP PHP, and composer ran in Cygwin just fine.
