如果你能相信的话，在安装作曲家时遇到问题。
iOS Sierra （10.12.6）
这是我的代码
Samers-MBP:~ samer$ php composer-setup.php
All settings correct for using Composer
Downloading...
php -r "unlink('composer-setup.php');"
Composer (version 1.5.2) successfully installed to:
/Users/samer/composer.phar
Use it: php composer.phar
Samers-MBP:~ samer$ php -r "unlink('composer-setup.php');"
Samers-MBP:~ samer$ sudo mv /Users/samer/composer.phar
/usr/local/bin/composer
Password:
Samers-MBP:~ samer$ composer
Could not open input file: /usr/local/bin/composer.phar
Samers-MBP:~ samer$ cd /usr/local/bin
Samers-MBP:bin samer$ composer
Could not open input file: /usr/local/bin/composer.phar
Samers-MBP:bin samer$
我只能使用 SUDO 运行作曲家
Samers-MBP:~ samer$ sudo composer info
Password:
Do not run Composer as root/super user! See
https://getcomposer.org/root for details
nesbot/carbon 1.22.1 A simple API extension for DateTime.
symfony/polyfill-mbstring v1.6.0 Symfony polyfill for the Mbstring
extension
symfony/translation v3.3.10 Symfony Translation Component
Samers-MBP:~ samer$
安装了 Laravel，但我无法访问$HOME/.bashrc（访问被拒绝）或~/.bash_profile将作曲家的系统范围的供应商 bin 目录放在我的$PATH中......
我不知道我做错了什么，或者为什么它不起作用。
运行
典型的安装说明后，我在MacOS Catalina上遇到了类似的问题：
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '795f976fe0ebd8b75f26a6dd68f78fd3453ce79f32ecb33e7fd087d39bfeb978342fb73ac986cd4f54edd0dc902601dc') { echo 'Installer verified'; } else { echo 'Installer corrupt';
unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
我怀疑它需要执行权限。初始权限为：
-rwxr-xr-x 1 username staff 1994202 Sep 25 08:39 composer
虽然它对我有执行权限，但我更改了它以/usr/local/bin制作其他所有内容：
-rwxr-xr-x 1 root wheel 1994202 Sep 25 08:39 composer
我仍然有这个错误：
Could not open input file: /usr/local/bin/composer.phar
我仔细检查了我的 PATH 变量：
% echo $PATH
/usr/local/bin:/usr/local/php5/bin:...
我找到了我的bash_profile文件，忘记了我在zsh上，所以我为我的zshrc文件提供了资源。
% source ~/.bash_profile
% source ~/.zshrc
还是没有骰子。最终我把文件名改成了composer.phar
% sudo mv /usr/local/bin/composer /usr/local/bin/composer.phar
然后它工作了
% composer

...
这在过去对我来说从来都不是必需的，但目前它正在发挥作用。
在终端上使用以下命令更改文件名
sudo mv /usr/local/bin/composer /usr/local/bin/composer.phar
然后输入"作曲家"
