Dotenv errors since Composer 1.7

[MWDelaney]

Hi,
Since Composer 1.7 was released earlier today, I can no longer install acf-pro-installer as part of a Trellis deployment; I get the following error(s) related to Dotenv/Dotenv:

Loading composer repositories with package information Installing

This seems related to #21 and #17 but I haven't seen this problem specifically until the new version of Composer shipped this morning.

Pinning Composer to 1.6.5 on the server I'm deploying to resolves the issue for me, but this obviously isn't a great fix.

@MWDelaney I have the exact same issue, but in my development environment.

I am quite new to Trellis, so I was hoping you could describe how you pin composer to 1.6.5 to fix this issue.

Thank you.

[MWDelaney]

@HansCz here’s what I did:

At the top of trellis/group_vars/all/main.yml

Replace this line:

composer_keep_updated: true

With this:

composer_version: 1.6.5

That got me going for the day but it’s not a good fix for the problem. Hopefully there’s a simple fix somewhere. It almost seems like dotenv isn’t available by the time acf-pro-installer needs it? Could it be an order of operations thing?

@PhilippBaschke any insight? I love this tool and I’d hate to have to find another solution!

[HansCz]

Got it working. Thanks @MWDelaney

For anybody else as new to this as me who needs the steps spelled out in greater detail, add the following steps to @MWDelaney's instruction:

• ssh into your virtual machine with vagrant ssh
• remove or rename /usr/local/bin/composer
• log out of the virtual machine
• run ANSIBLE_TAGS=composer vagrant provision from inside trellis directory to reprovision composer.

Explanation of removal/renaming:
if you do not rename or remove the composer executable, the composer playbook will find an already existing composer installed and skip the reinstallation.
see trellis/vendor/roles/composer/tasks/main.yml line 7:

- name: Check if Composer is installed.
  stat: "path={{ composer_path }}"
  register: composer_bin

- name: Download Composer installer.
  get_url:
    url: https://getcomposer.org/installer
    dest: /tmp/composer-installer.php
    mode: 0755
  when: not composer_bin.stat.exists

- name: Run Composer installer.
  command: >
    {{ php_executable }} composer-installer.php {% if composer_version != '' %} --version={{ composer_version }}{% endif %}
    chdir=/tmp
  when: not composer_bin.stat.exists

- name: Move Composer into globally-accessible location.
  shell: >
    mv /tmp/composer.phar {{ composer_path }}
    creates={{ composer_path }}
  when: not composer_bin.stat.exists

[MWDelaney]

It looks like this related issue with wp-cli has been acknowledged by Composer and a fix is in progress. Hopefully that fix resolves this issue, too.

Composer has been patched. Updating to v1.7.1 solves the issue for me.
