Php module xmlwriter not installed

I had same problem while moving to new server:

1) Check that libxml installed:

php -i | grep "xml"

Result example:

1   /etc/php.d/xmlreader.ini,
2   /etc/php.d/xmlwriter.ini,
3   xmlrpc_error_number => 0 => 0
4   xmlrpc_errors => Off => Off
5   libxml
6   mbstring.http_output_conv_mimetypes => ^(text/|applicatio...
7   Simplexml support => enabled
8   xml
9   libxml2 Version => 2.7.6
10  xmlwriter

Lines 5, 9 & 10 told us that all ok.

2) If not installed (example for CentOS):

yum install libxml2

and restart server:

/etc/apache2 restart

or php-fpm:

/etc/php-fpm restart

maybe will useful next variants:

yum install php-xmlwriter
yum install php-xml

For php from sources in latest versions xmlwriter enabled by default, but you can check, that key --disable-xmlwriter not set.

3) Last step - file:

/etc/php.d/xmlwriter.ini

Needing to be look like:

; Enable xmlwriter extension module
extension=xmlwriter.so

I think latest string - it's main decition for the problem.

Question

when i installed wp all import plugin, it gave me this error: " Required PHP components are missing.

WP All Import requires DOMDocument, XMLReader, and XMLWriter PHP modules to be installed. These are standard features of PHP, and are necessary for WP All Import to read the files you are trying to import. Please contact your web hosting provider and ask them to install and activate the DOMDocument, XMLReader, and XMLWriter PHP modules."

I've started using a library that requires xmlwriter PHP extension, and it seems like it is not installed on my server.

How can I install it?

I tried this:

sudo yum install libxml2

but the result is:

There are no enabled repos.

Is there another way to install it, for example using apt-get? Or how can I install it?

I did it with:

sudo apt-get install php-xml
sudo service apache2 restart

This confirms xmlwriter is installed:

php -i | grep "xml"

The package manager yum is not used on debian distros like Ubuntu. It's used on Fedora and RHEL. :)

What @user838550 wrote should work. If you've got 5.6 running use sudo apt install php5.6-xml
