Message: Set sys_temp_dir in your php.ini after installed composer

问题

I've tried to install composer for my CodeIgniter project.

The installation was successful. But, when I type on command-line composer --version, it shows:

PHP temp directory (C:\Users\petik\AppData\Local\Temp) does not exist or is not writable to Composer. Set sys_temp_dir in your php.ini
Composer version 1.4.2 2017-05-17 08:17:52

Can anyone help?

回答1:

Change TEMP folder in php.ini. look for entry sys_temp_dir in your php.ini file and change the tmp location and set correct permissions.

回答2:

Or if you use Windows you have to run your command line like an administrator "Run as administrator"

I have same error on an debian where /tmp partition was full. Purge rm -rf /tmp/*, and message gone. May this help.

For this error, If you don't have permission to edit php.ini file. My temporary solution is:

php -d open_base_dir="." -d sys_temp_dir="." /usr/local/bin/composer -v

You can run all your composer commands like this:

php -d open_base_dir="." -d sys_temp_dir="." /usr/local/bin/composer install
php -d open_base_dir="." -d sys_temp_dir="." /usr/local/bin/composer update

You can also use this command in other operations e.g.: In magento2 for phpcbf:

php -d open_base_dir="." -d sys_temp_dir="."  vendor/bin/phpcbf --standard=Magento2 magento2/app/code/example/StockReserve --report-file="StockReserveAutoFixed.txt"

php -d sets variable in command line.
