Composer给我[ErrorException]未定义的索引:安装后的用户名

Question

我在Ubuntu上，我已经按照composer网站指南安装了composer：

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '756890a4488ce9024fc62c56153228907f1545c228516cbf63f885e036d37e9a59d27d63f46af1d4d07ee0f76181c7d3') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

然后我按照以下说明操作：

最有可能的情况是，您希望将composer.phar放入PATH上的一个目录中，因此您可以简单地从任何目录调用composer(全局安装(，例如：

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

现在，当我调用composer -v时，我得到了这个错误：

composer -v

Answer 1

在我的情况下，这是因为COMPOSER_HOME中的auth.json。

{
"http-basic": {
"http-basic": {
"php.fury.io": {
"username": "",
"password": ""
}
},
}
}
// should be
{
"http-basic": {
"php.fury.io": {
"username": "",
"password": ""
}
}
}

这似乎就像一位作曲家试图寻找的"用户名"；在"；http基本"；但它找不到它，并导致未定义的"；用户名"；索引错误。
