Hi @Mohammadrezaarch Do you get this error after you type the `conda install .... compas` line in the terminal? Or where exactly? Cheers ---

I think ,404,it has solved, But I cant install. I dont know where I can type,conda install … compas, this? I tried it inside the rhino command and not worked, and I don’t know where I can type in anacoda? becaused ithas different environments. ![1](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/4c7d7536e34f953bbad3c697cf325ed3fbacff4d.jpeg) ---

You should type the installation commands from the `Anaconda Prompt`. You can find it if you open the `Start` menu of Windows, and start typing `Anaconda Prompt` in there. It should open something like this: ![image](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/856c7728b9c953903b712be89e896088a3f7e062.png) In that window, type the following lines: ```bash conda config --add channels conda-forge conda create -n NAME_OF_YOUR_ENVIRONMENT python=3.8 compas --yes ``` (obviously replace `NAME_OF_YOUR_ENVIRONMENT` for whatever you want to name the environment) Once the install is done, you can: 1. activate it with: ```bash conda activate NAME_OF_YOUR_ENVIRONMENT ``` 1. make it available inside Rhino: ```bash python -m compas_rhino.install ``` Cheers ---

You had a typo when you added `conda-forge` the first time: ![image](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/248169b11561cc9eb44dd3f22db517daf9b3748e.png) Try removing it first: ```bash conda config --remove channels conda-foge ``` and then retry the installation. ---

Check the docs, this is a documented scenario: [https://compas.dev/compas/installation.html#microsoft-visual-c-build-tools-1](https://compas.dev/compas/installation.html#microsoft-visual-c-build-tools-1) What happens is that you probably haven’t ever installed any build tools on that machine, so, you need a one-off install of Visual C++ stuff. (Actually, if you see inside the whole pile of error messages, this is what it says, it’s just a bit hard to read in the mess of text). ---

Thank you so much, I instaled build tools. when I try to " pip install -e the massage is that: -e option requires an argument ![7](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/b5d44085a862181b79152ae2209e8f32676fe204.jpeg) ---

You can only use `pip install` to install from local disc. For that you have to download the repositories you want to install from BRGs gitbhub manually or use a client like Sourcetree or SmartGit. After downloading open conda prompt navigate to the folder of the downloaded repository via `cd` command and then you can use `pip install -e .` to install it. ---

For example, I downloaded Compas singular. So, How can I give navigation of this folder to aconda prompt? Is there any place for instruction, to follow? ![9](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/6675421368a3707851879c3a1e03949e8eb431ae.jpeg) ---

“from compas\_plotters.meshplotter import MeshPlotter” Also this comand doesnt work. I dont know from where I can install it. ---

Your normal path in command prompt is C:\Users\username There I have a folder named Code with the path C:\Users\username\Code and my compas\_singular folder is at C:\Users\username\Code\compas\_singular. To navigate there I type `cd Code/compas_singular`. Check how the change directory `cd` command works e.g. here: [https://www.digitalcitizen.life/command-prompt-how-use-basic-commands](https://www.digitalcitizen.life/command-prompt-how-use-basic-commands) Regarding the mesh plotter, I’m not sure, a lot of the artists (maybe also plotters?) work only directly in rhino python - but I might be wrong. The script you copied is ment for rhino python, most examples in the gitbook are. For examples of compas\_singular in gh go to compas\_/singular/examples/grasshopper, there are some gh example files and user objects you can use. ---

I guess the best explanation for manual installation of compas packages is the rv2 gitbook: [https://blockresearchgroup.gitbook.io/rv2/documentation/dev-install](https://blockresearchgroup.gitbook.io/rv2/documentation/dev-install) It also shows how to pip install it directly from github without manual download Regarding your screencap: Did you download the master branch of compas singular (and if you downloaded manually unpacked it)? The content of the folder should look sth like this and there you also see the setup.py pip needs to install the package ![Unbenannt](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/528c4fe5db3999361f510be9bfb31c5acb3233ef.png) Additionally (don’t know if this is mentioned in the compas singular gitbook) you need to make every compas package aviable in rhino e.g. `python -m compas_rhino.install -p compas_singular compas_skeleton compas_triangle compas_tna` (you can just list the packages after the initial command). ---
