用这个:

php -r "readfile('https://getcomposer.org/installer');" | php

我已经修复了以下步骤相同的问题

打开项目目录Using Terminal(您正在使用的终端，即mintty) 现在按照https://getcomposer.org/download/上给出的说明在这个目录中安装composer

PHP -r "copy('https://getcomposer.org/installer'， 'composer-setup.php');" php -r "if (hash_file('SHA384'， 'composer-setup.php') === 'the-provided-hash-code') {echo '已验证安装程序';} else {echo '安装程序损坏';分离(“composer-setup.php”);} echo PHP_EOL;" php composer-setup.php PHP -r "unlink('composer-setup.php');"

现在执行你的命令。

现在一切都很顺利，因为作曲家。Phar文件在当前项目目录中可用。

谢谢

我在Windows上遇到了同样的问题，并使用了不同的解决方案。我使用composer网站提供的composer . setup .exe安装文件，它会进行全局安装。

安装之后，确保你的PATH变量指向composer所在的目录。Phar被存储。这通常是C:\ProgramData\ComposerSetup\bin (ProgramData可能是一个隐藏目录)。这是不言而喻的，但也要确保PHP可执行文件也在PATH变量中。

然后你可以简单地打电话

composer install

而不是

php composer.phar install

朋友们，请按照以下步骤在MAC OS中修复此问题

Step 1: first run the command in Terminal with your project directory $ curl -sS https://getcomposer.org/installer | php Step 2: Move the composer.phar in your project directory $ mv composer.phar /Applications/MAMP/htdocs/bashrushAPI/composer.phar Step 3: Setup alias the composer $ alias composer='/Applications/MAMP/htdocs/bashrushAPI/composer.phar' Step 4: Check the composer version now $ composer --version Composer version 1.7.2 2018-08-16 16:57:12 Step 5: Confirm the project folders and file placed on bellow $ ls CONTRIBUTING.md docker-compose.yml templates README.md logs tests composer.json phpunit.xml vendor composer.lock public composer.phar src Step 6: Now update composer $ composer.phar update Loading composer repositories with package information Updating dependencies (including require-dev) Nothing to install or update Generating autoload files Step 7: Run your sample project $ php composer.phar start php -S localhost:8080 -t public [Thu Sep 27 03:16:11 2018] ::1:51177 [200]: / [Thu Sep 27 03:16:11 2018] ::1:51178 [404]: /favicon.ico - No such file or directory

如果你想创造作曲家。Phar文件在任何文件夹遵循此命令。

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

php -r "if (hash_file('sha384', 'composer-setup.php') === 'c5b9b6d368201a9db6f74e2611495f369991b72d9c8cbd3ffbc63edff210eb73d46ffbfce88669ad33695ef77dc76976') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php

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

昨天，我试图在Windows 10上安装Yii2框架，运行这个命令时遇到了同样的问题(无法打开输入文件:composer.phar):

php composer.phar create-project yiisoft/yii2-app-advanced advanced 2.0.9

问题是作曲家。PHR文件不在当前目录中，您需要给出完整路径编写器。phr像

php C:\ProgramData\Composer\bin\composer.phar create-project yiisoft/yii2-app-advanced advanced 2.0.9

或者你可以使用以下命令创建yii2项目:

 composer create-project yiisoft/yii2-app-advanced advanced 2.0.9

Or

composer.phar create-project yiisoft/yii2-app-advanced advanced 2.0.9
