'PHP Composer - Unable to install composer on macOS Sierra

I'm trying to install composer running the command provided on the getcomposer.org/download documentation site:

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

But I get an error message saying:

Warning: copy(): SSL operation failed with code 1. OpenSSL Error messages:

I had same issues but this what I did:

  • I copy paste this into the terminal php -r "copy('http://getcomposer.org/installer', 'composer-setup.php');" on the terminal which download the composer to the directory where you are currently In.

(the problem was causing because of the https protocol)

  • And then php composer-setup.php --install-dir=/usr/local/bin --filename=composer run this command, which installs the Composer to my bin folder so that i could run it globally.

  • Then you have to unlink the composer php -r "unlink('composer-setup.php');"

  • Finally check the see the Composer installed composer -V.

Good Luck !

I had the same problem- here is the right way

  1. clean dir > Terminal > mkdir composer

  2. cd composer

  3. curl -sS https://getcomposer.org/installer | php

  4. sudo mv composer.phar /usr/local/bin/

    vim ~/.bash_profile

  5. alias composer="php /usr/local/bin/composer.phar"

I had same issues but this what I did:

  • I ran curl -sS https://getcomposer.org/installer | php on my terminal which made composer to be installed on my PC.
  • And then I moved Composer to my bin folder so that i could run it globally mv Composer.phar usr/local/bin/composer.

It works for me as follows:

I ran

curl -sS https://getcomposer.org/installer | php

on my terminal which made composer to be installed on my PC. And then I moved Composer to my bin folder so that I could run it globally:

mv Composer.phar usr/local/bin/composer

The instructions in Composer official page is sometimes confusing

or not working on macOS Sierra.

But installation is still simple like before.Just simply run two lines of command on your Terminal.

  1. curl -sS https://getcomposer.org/installer | php
  2. mv composer.phar usr/local/bin/composer

Solution 6:[6]

I have same problem and I try this step:

  1. Open your terminal

  2. Copy this code in your php folder, In My laptop, I have use lampp then I go to xampp folder.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

php composer-setup.php --install-dir=/usr/local/bin --filename=composer

  1. So, if you have get this message below:

All settings correct for using Composer Downloading...

Composer (version 2.0.8) successfully installed to: /usr/local/bin/composer Use it: php /usr/local/bin/composer

  1. You can copy this code:

    php -r "unlink('composer-setup.php');"

  2. Untill here you have succesfully install composer

  3. Check it with this code composer

Thanks

Please don’t use any of it. I’m not saying its wrong.

Please follow the link https://getcomposer.org/download/ for installing latest version of composer.

The reason is because hen you download from getcomposer.org you are downloading latest file like https://getcomposer.org/installer & composer-setup.php.

And comparing with wrong SHA384 hash_file (like e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae), so it will not work.

I had also the same issues to install composer after a clean install of macOS Sierra. My solution to get it work:

  1. Open your terminal
  2. sudo php -r "copy('http://getcomposer.org/installer', 'composer-setup.php');"
  3. sudo php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
  4. sudo php composer-setup.php
  5. sudo php -r "unlink('composer-setup.php');"
  6. sudo mv composer.phar /usr/local/bin/composer

To verify if it's all installed properly type: composer -V

Solution 9:[9]

You can also just put composer.phar (which is what you end up with after you do the install) wherever you want and create a symlink in /usr/local/bin/composer to it using ln -s

I use this method .and works fine for me on ubuntu 17.10

1-create file bash

1-1 Create a directory on the desktop.And then open the terminal

 sudo touch sh1.sh
 sudo 777 sh1.sh

2-edited file sh1.sh writing this statements 

 #!/bin/sh

 EXPECTED_SIGNATURE="$(wget -q -O - https://composer.github.io/installer.sig)"
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
ACTUAL_SIGNATURE="$(php -r "echo hash_file('SHA384', 'composer-setup.php');")"

if [ "$EXPECTED_SIGNATURE" != "$ACTUAL_SIGNATURE" ]
then
    >&2 echo 'ERROR: Invalid installer signature'
    rm composer-setup.php
    exit 1
fi

php composer-setup.php --install-dir=/usr/local/bin --filename=composer
RESULT=$?

exit $RESULT

3-on terminal run 

./sh1.sh

Solution 11:[11]

Please just copy the link and paste it to your terminal:

curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

Now you can run composer without any error....

You can easily download PHP Composer by following the official documentation, here's the link

These are the steps.

  1. php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
  2. php -r "if (hash_file('sha384', 'composer-setup.php') === '906a84df04cea2aa72f40b5f787e49f22d4c2f19492ac310e8cba5b96ac8b64115ac402c8cd292b8a03482574915d1a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
  3. php composer-setup.php
  4. php -r "unlink('composer-setup.php');"
