Ubuntu fails to execute composerupdate using www-data.

The project is put on github and a webhook is made. The server detects the post from github. If the master node changes, run {code...} to pull the code. At last, the compoer in the master Branch is also detected. when json is modified, run the following command: {code ...... the project is put on github and a webhook is made. The server detects the post from github. If the master node changes, execute

cd /path;git pull git@ooxxx.com

There is no problem with pulling the code above.

At the same time, if the compoer. json in the master branch is modified, run the following command:

php composer.phar updatephp composer.phar dump-autoload -o

Because the post data from github is executed by git pull using the www-data specified by apache (the deployed public key is also the user), the above composer operations cannot be executed, the following prompt is displayed when I manually operate composer update on the server:

···
Sudo-u www-data php composer. phar update
Cannot create cache directory/root/. composer/cache/repo/http---packagist.phpcomposer.com/, or directory is not writable. Proceeding without cache
Cannot create cache directory/root/. composer/cache/files/, or directory is not writable. Proceeding without cache
Loading composer repositories with package information
Updating dependencies (including require-dev)
Generating autoload files
···
Similarly, I tried to install composer globally and used php/usr/local/bin/composer update.

Search for GG and try to change the/root/. composer directory to www-data and 777

root@localhost:~# ls -la ~/.composer/cachetotal 20drwxrwxrwx 4 www-data www-data 4096 Dec 30 14:53 .drwxrwxrwx 3 www-data www-data 4096 Dec 30 14:53 ..drwxrwxrwx 2 www-data www-data 4096 Dec 30 14:53 files-rwxrwxrwx 1 www-data www-data   13 Dec 30 14:53 .htaccessdrwxrwxrwx 3 www-data www-data 4096 Dec 30 14:53 repo

In addition, the composer. phar and/usr/local/bin/composer owner of the project root directory are set to www-data, and the problem persists.

Ask how to solve the problem.

Ps: add,There is no problem with performing operations such as composer update with root.

Change the cache directory.
