‘pecl install’ fails on Plesk for Linux server: shtool at /tmp does not exist or is not executable

On a Plesk for Linux server, an error similar to below one occurs on attempt to use the command pecl install:
# /opt/plesk/php/7.1/bin/pecl install memcached
…
shtool at ‘/tmp/memcached/build/shtool’ does not exist or is not executable.
Make sure that the file exists and is executable and then rerun this script.
ERROR: `phpize’ failed
The directory /tmp is mounted with the flag noexec:
# mount | grep /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,noexec,noatime)

Installation of PHP modules fails because of the noexec flag on the /tmp directory.

Use one of the solutions:

Connect to the server using SSH.
Remount the directory /tmp with the flag exec:

# mount -o remount,exec /tmp

Connect to the server using SSH.
Create new temporary directory on a partition that mounted with exec option, for example:

# mkdir /root/tmp
Change temporary directory for pecl to this newly created directory:

# /opt/plesk/php/7.1/bin/pear config-set temp_dir /root/tmp

or

# /opt/plesk/php/7.1/bin/pecl config-set temp_dir /root/tmp
