file_put_contents(config.json): failed to open stream: No su

Question

我正在尝试使用私有存储库更新composer:

php composer.phar update
An existing OAuth token for Composer is present and will be reused [ErrorException] file_put_contents(/srv/data/.composer/config.json): failed to open stream: No such file or directory

我的用户不允许写入此目录/srv/data/。

我的问题是如何改变config.json目录?

I have try:

 php.composer.phar config --list

您可以使用COMPOSER_HOME环境变量更改编写器目录的位置。

COMPOSER_HOME=/some/writable/path php composer.phar update
