Don't think this has any relation to the PECL archive extension, so I doubt anyone from PEAR will see this.

To check, /usr/local/Cellar/php/7.4.0/share/php/pear/Archive/Tar.php exists?

This is certainly unrelated to PECL/archive.

Hmm, sorry about that. There wasn't a "PEAR" option in the "Package affected" list so I posted it under PECL which in hindsight maybe wasn't the best choice.

Well, it sounds like permission. execute under root alias. by executing:

sudo pecl install APCu

Most programs are deliberately restricted what they can access on a linux system, and in most cases, like installation, it required root privileges. Only use sudo and never log as root.

There are three ways, but it depends on your distro.

for Ubuntu, and other Debain type distros:

sudo apt-get update
sudo apt-get install php7.0-apcu -y

then sudo service php7.0-fpm restart (nginx) or sudo service apache2 reload

Debain-version has a configuration script


But on non debain systems that use apt-get, use this (which is the method you tried):

sudo apt-get update
sudo apt-get install php-pear -y
sudo pecl install apcu

add the plugin extension

echo "extension = apcu.so" | sudo tee -a /etc/php/7.0/mods-available/apcu.ini

Then add the symbol links for whatever webserver/service

Nginx (web and the command line interface (CLI) examples):
sudo ln -s /etc/php/7.0/mods-available/apcu.ini /etc/php/7.0/fpm/conf.d/30-apcu.ini
sudo ln -s /etc/php/7.0/mods-available/apcu.ini /etc/php/7.0/cli/conf.d/30-apcu.ini

Apache example:
sudo ln -s /etc/php/7.0/mods-available/apcu.ini /etc/php/7.0/apache2/conf.d/30-apcu.ini


then restart your web server:

sudo service php7.0-fpm restart (nginx) or sudo service apache2 reload (apache2)


The last way would be source code....

sudo apt-get update
sudo apt-get install php7.0-dev git build-essential -y
cd /tmp
git clone https://github.com/krakjoe/apcu
cd apcu
phpize
./configure
make
sudo make install

add the php extension:

echo "extension = apcu.so" | sudo tee -a /etc/php/7.0/mods-available/apcu.ini

Then add Symbol links:
for nginx:

sudo ln -s /etc/php/7.0/mods-available/apcu.ini /etc/php/7.0/fpm/conf.d/30-apcu.ini
sudo ln -s /etc/php/7.0/mods-available/apcu.ini /etc/php/7.0/cli/conf.d/30-apcu.ini

or for apache:

sudo ln -s /etc/php/7.0/mods-available/apcu.ini /etc/php/7.0/apache2/conf.d/30-apcu.ini

 then restart web server:

sudo php7.0-fpm restart

or
sudo service apache2 reload

I just noticing you are using macOS Catalina.

there are package managers like apt-get for the mac ( like Brew) but it would depend on if the author made it available in those BSD (macOs) channels.

Hey drtechno, thanks for helping out, Yeah, I've installed PHP through Homebrew (see my first comment). I use brew to install PHP and then pecl or PEAR to install any extensions.

That is because PEAR has its own bugtracker[1].  So if this is
indeed a bug in PEAR, it should probably be reported there.

> That is because PEAR has its own bugtracker[1].

Are you sure that issue tracker is still maintained? The youngest PHP version to report an issue with is 5.4. So I can't report an issue with 7.4.

> Are you sure that issue tracker is still maintained?

I'm pretty sure that it's not. :(  However, having the ticket here
doesn't make much sense either.

Or has this been resolved in the meantime?

I have to admit that I totally lost track of this. I haven't used PEAR in ages.

> I haven't used PEAR in ages.

Me neither, but this is about `pecl install APCu` which failed for
you with a PEAR related issue.

Seems to be resolved now! Thanks

Thanks for checking!
