我在php中得到一个未定义的curl_version（）函数

Question

I added Paypal Express checkout plugin to my website. I get this error:

2019-07-23T15:45:32+00:00 CRITICAL Uncaught Error: Call to undefined function PayPal\Core\curl_version() in /var/www/html/wp-content/plugins/woo-paypal-express-checkout/includes/php-library/paypal-rest/lib/PayPal/Core/PayPalHttpConfig.php:65

and this is the line

$curl = curl_version();

What can I do to resolve this probleme I tried to install php-curl but I always got the same result I used

sudo apt-get install php5-curl sudo service apache2 restart

It sounds like you are missing the PHP CURL extension. This is usually bundled as a separate package. If you are using Ubuntu, apt-get install php-curl (or php7.2-curl) will install the missing dependency. You may need to enable the module after installing it using phpenmod curl. If you are using another Linux distribution, please consult the appropriate distribution documentation for installing PHP modules.
