### How to install OSM Client in Windows with WSL

OSM client can be easily installed in Windows by installing an Ubuntu distro on Linux with [Windows Subsystem for Linux (WSL)](https://docs.microsoft.com/en-us/windows/wsl/install).

Once WSL is installed with an Ubuntu 20.04 distro, you can install OSM following the instruccions in (#how-to-install-osm-client-in-ubuntu-2004)

### How to install OSM Client directly in Windows with Conda and Git

OSM can also be installed in Windows with [Miniconda](https://docs.conda.io/en/latest/miniconda.html) and [Git](https://git-scm.com/)

You can install both programs with [Chocolatey](https://chocolatey.org/), the package manager for Windows. Open a CMD window and run the following commands:

```cmd

choco install -y git make wget

choco install -y miniconda3

```

Then, open Windows environment variables > User environment variables, and add the following entries to the `Path` user environment variable in order to make Conda executables reachable from all terminals:

- `C:\tools\miniconda3`

- `C:\tools\miniconda3\Scripts`

- `C:\tools\miniconda3\Library\bin`

Make sure that aliases for Python are disabled in Windows Configuration. Go to Settings > Apps > Apps & features, and click on "Manage app execution aliases". Then disable aliases for Python.

Open Git Bash and run the following commands to create a Conda environment with Python 3.8 and initialize all shells to work with Conda:

```bash

conda create -n osm-env python=3.8

conda init --all

# Logout

```

Then install OSM client as follows:

```bash

# Install conda and install some packages via conda (which will install dependent libraries)

conda activate osm-env

conda install pycurl==7.45.1

# Upgrade pip to the latest version (with sudo, to install it globally for all users)

python -m pip install -U pip

# Decide which version to use (e.g., v12.0)

export OSM_CLIENT_VERSION=v12.0

# Clone IM repo and checkut the desired version

git clone https://osm.etsi.org/gerrit/osm/IM

git -C IM checkout ${OSM_CLIENT_VERSION}

# Install OSM IM using pip

python -m pip install -r IM/requirements.txt

# make -C IM clean

python -m pip install ./IM

# Clone osmclient repo and checkut the desired version

git clone https://osm.etsi.org/gerrit/osm/osmclient

git -C osmclient checkout ${OSM_CLIENT_VERSION}

# Install osmclient using pip

python -m pip install -r osmclient/requirements.txt

# Required DLLs for python-magic

python -m pip install python-magic-bin

python -m pip install ./osmclient

# Try OSM client

python -m osmclient.scripts.osm

# Logout from Git Bash

```

Open Git Bash again and edit `.bash_profile` to activate the Conda environment persistently. If desired, add an alias to osm executable:

```bash

conda activate osm-env

alias 'osm=python -m osmclient.scripts.osm'

```

That will complete OSM client installation for Windows.
