Cannot create /conf.d/docker-php-ext-pcntl.ini: Directory nonexistent

Recently we’re getting the following error in our recent builds. AFAIK nothing has changed in our config so we’re not sure why it is being caused all of a sudden and how it can be resolved?

When it is installing the php packages the error shows up at the end…

Readers will probably need to see your config, to see how you are kicking off that extension build.

Also, can you not load a pcntl extension from your upstream distribution repo, rather than compiling it?

Seems like a recent update in the CircleCI PHP Docker images broke something. The PHP_INI_DIR environment variable that’s normally set by the docker/php image that CircleCI’s image pulls from isn’t being set correctly.

Here’s an example of a CircleCI config that fails:

Hello,

The following steps also fails:

run: sudo docker-php-ext-install zip pcntl pdo_mysql gmp bcmath

With the following error:

Installing shared extensions: /usr/local/lib/php/extensions/no-debug-non-zts-20160303/
/usr/local/bin/docker-php-ext-enable: 108: /usr/local/bin/docker-php-ext-enable: cannot create /conf.d/docker-php-ext-pcntl.ini: Directory nonexistent
Exited with code 123

I’m using the circleci/php:7.1-browsers image.

This only started happening 2 weeks ago.

One fix to this, albeit temporary, was to add a -E in the command. Like this

command: sudo -E docker-php-ext-install zip intl sodium pcntl bcmath

According to the man page this does this:

Indicates to the security policy that the user wishes to preserve their existing environment variables. The security policy may return an error if the user does not have permission to preserve the environment.
