我用的是windows 8.0。在我的情况下，安装或更新我只是使用composer install或其他东西，而不是php composer.phar。这对我很有效 就像

composer require google/apiclient:1.*

如果你按照下面的指示去做:

https://getcomposer.org/doc/00-intro.md

它告诉你做以下事情:

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

那么，很可能您和我一样，运行了这些命令，而没有阅读页面的下一部分，告诉您停止引用composer。Phar的全名和缩写为可执行文件(您刚刚用mv命令重命名了它)。所以这个:

$ php composer.phar update friendsofsymfony/elastica-bundle

变成这样:

$ composer update friendsofsymfony/elastica-bundle

如果你使用的是Ubuntu/Linux并且你正在尝试运行

php的作曲家。Phar需要在命令行上进行干预/图像。

使用sudo composer require intervention/image代替。这会给你想要的东西。

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

我收到包裹时遇到了点麻烦。运行composer dumpautoload的Json脚本。

我有文件/usr/local/bin/composer。Phar，还有文件~/。bash_profile(在OSX)包含:

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

这允许编写器从命令行工作，但不允许脚本执行编写器。

解决办法是这样的:

$ cd /usr/local/bin
$ mv composer.phar composer
$ sudo chmod +x composer // +x allows the file to be executable, such as by CLI scripts

无法打开输入文件:/usr/local/bin/composer.phar

修复是更新~/。Bash_profile (sudo nano ~/.bash_profile)，并将composer别名更改为:

alias composer="php /usr/local/bin/composer"

# ie: `.phar` extension removed

现在一切都像预期的那样。

分两步。

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

Sudo PHP编写器。phar更新
