As @Waqleh said, you have to uninstall composer and install it again. First execute:
正如@Waqleh 所说，您必须卸载 Composer 并重新安装。首先执行：
sudo apt-get remove composer
sudo apt-get remove composer
Then, execute these commands (from https://getcomposer.org/download/) (checksum for 1.10.1):
然后，执行这些命令（来自 https://getcomposer.org/download/）（1.10.1 的校验和）：
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === 'e0012edf3e80b6978849f5eff0d4b4e4c79ff1609dd1e613307e16318854d24ae64f26d17af3ef0bf7cfb710ca74755a') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
Now move composer.phar to a directory that is in your path (fom https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx):
现在将 composer.phar 移动到您路径中的目录（来自https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx）：
sudo mv composer.phar /usr/local/bin/composer
And execute composerfrom any directory. That's all!
并composer从任何目录执行。就这样！
PS: If you're using PHPStorm (or maybe other IDE's) you'll have to close it and open again.
PS：如果您使用的是 PHPStorm（或其他 IDE），则必须关闭它并再次打开。

sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
php -r "unlink('composer-setup.php');"
after some time passed, you can update and no need to use sudoprefix:
经过一段时间后，您可以更新而无需使用sudo前缀：
composer self-update

I've installed brew and it saves me a lot.
Install brew then brew install composerto install the composer.
我已经安装了 brew，它为我节省了很多。安装 brew 然后brew install composer安装作曲家。
