作曲家更新中的错误

Question

I tried to do a composer update command and got this error. What might be the problem?

It was working well before.

[RuntimeException]  
Could not delete /var/www/vhosts/kaikacampus.com/httpdocs/kaikacampus.com/vendor/
doctrine/annotations/phpunit.xml.dist: date_defaut_timezone_get():It is not safe 
to reply on the system's timezone settings. You are *required* to use the 
data.timezone setting or the date_default_timezone_set() function. In case you 
used any of those methods and you are still getting this warning, you most 
likely misspelled the timezone identifier. We selected the timezone 'UTC' for 
now, but please set date.timezone to select your timezone.

I'm not sure about the suggestion given in the red area as I'm a newbie.

The composer version is: Composer version 1.0-dev (ffffab37a294f3383c812d0329623f0a4ba45387) 2014-11-05 06:04:18

Answer 1

Performed the action:

mv vendor vendor_old && composer update

This saved my day!!!

Answer 2

What might be the problem?

If you take a look at the screenshots you see a bigger red section (circa the lower half of the screenshot).

It contains an error messages that starts about telling what went wrong. It then has a colon (":") and after the colon, the reason what the problem is, has been given to you.

It is a common PHP error message, for which references should exist. Both on site as well as on other websites in the internet. As you're inclined to search and research before posting, I assume it's okay I leave the straight forward search operation as an exercise to you.

Let me know if you've got problems to read the screen because of the colors used or the size of the letters.

As added your first comment, it looks you're puzzled about where to make the timezone changes, right? The error message is speaking about

"the date.timezone setting"

(bold by me). When you don't understand what this means, one thing easy to do in PHP is to prefix it with php.net/ and enter it into your browser:

http://php.net/date.timezone

This brings you directly to the documentation of that setting.

Answer 3

You need to set a timezone for your server/computer.

You should first locate your php.ini file. You will find the path of it in the output of this command:

php -i | grep -e 'Loaded Configuration'

Then load it in your browser (for example http://localhost/info.php ) and check in the page that opens where your php.ini is located.

When you know where it is, open the php.ini file, look for date.timezone setting, change it and save the file.
