Windows Development Environment: Trellis

Trellis relies on a few other software tools. Install these tools:

  • VirtualBox >= 4.3.10 (install on Windows)
  • Vagrant >= 1.8.5 (install on Windows)
  • Ansible >= 2.4 (install in WSL)


Download and install the latest version of VirtualBox for Windows.


Download the latest version of Vagrant for Windows.

Then alias vagrant in WSL to vagrant.exe:

⚠️ The following commands must be run from WSL (Windows Subsystem for Linux).

$ echo 'alias vagrant=vagrant.exe' >> ~/.bashrc
$ source ~/.bashrc


⚠️ The following commands must be run from WSL (Windows Subsystem for Linux).

Install pip (Python package manager) if you don't already have it:

$ sudo apt-get install python-pip

Install Ansible with pip:

$ pip install ansible

# Install a specific Ansible version:
$ pip install ansible==


Maximum recursion depth exceeded

If you run into a "maximum recursion depth exceeded" error while provisioning, try downgrading Ansible to 2.5.1 (pip install ansible==2.5.1) and then re-provisioning.

You'll also need to update your vagrant.default.yml so that vagrant_ansible_version references 2.5.1:

-vagrant_ansible_version: '2.7.5'
+vagrant_ansible_version: '2.5.1'

vagrant ssh doesn't work


$ echo 'alias vssh="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no vagrant@ -i ./.vagrant/machines/default/virtualbox/private_key -p"' >> ~/.bashrc
$ source ~/.bashrc

Slow site

If your site loads extremely slowly, try installing the vagrant-winnfsd plugin. In some cases this plugin can cause problems, so you may need to uninstall it if things get worse.

⚠️ The following commands must be run from WSL (Windows Subsystem for Linux).

$ vagrant plugin install vagrant-winnfsd
$ vagrant reload # if Vagrant was already running

If vagrant-winnfsd causes problems, before uninstalling it you can try forcing it to mount using TCP instead of UDP by adding nfs_udp: false to the NFS mount point configuration lines in your Vagrantfile.
