Issues while installing pear.phpunit.de/PHPUnit

Question

I'm trying to tell pear that where to find PHPUnit by using this command:

sudo pear channel-discover pear.phpunit.de

The output was:

Discovering channel pear.phpunit.de over http:// failed with message: channel-add: Cannot open "http://pear.phpunit.de/channel.xml" (File http://pear.phpunit.de:80/channel.xml not valid (received: HTTP/1.1 410 Gone
))
Trying to discover channel pear.phpunit.de over https:// instead
Discovery of channel "pear.phpunit.de" failed (channel-add: Cannot open "https://pear.phpunit.de/channel.xml" (File https://pear.phpunit.de:443/channel.xml not valid (received: HTTP/1.1 410 Gone
)))

I tried the following commands:

sudo pear channel-update pear.php.net
sudo pear upgrade-all

Then I ran channel-discover command again. I got same error as shown above.
I even tried these commands:

sudo pear config-set auto_discover 1

Output:

config-set succeeded

Then I tried this command:

sudo pear install pear.phpunit.de/PHPUnit

Output:

Attempting to discover channel "pear.phpunit.de"...
Attempting fallback to https instead of http on channel "pear.phpunit.de"...
unknown channel "pear.phpunit.de" in "pear.phpunit.de/PHPUnit"
invalid package name/package file "pear.phpunit.de/PHPUnit"
install failed  

So I visited this link: https://pear.phpunit.de/channel.xml and it displayed 410 gone error. Is there any other alternate way to do this?

Answer 1

You can't install phpunit using pear anymore: https://github.com/sebastianbergmann/phpunit/wiki/End-of-Life-for-PEAR-Installation-Method

But you can still install it using the phar file: https://phpunit.de/getting-started.html

Or using composer: https://phpunit.de/manual/current/en/installation.html#installation.composer

Most people just composer nowadays. But since you seem to be on Ubuntu you can always do:

sudo apt-get install phpunit
