hi, did you install `compas_fab` in the “compas-dev” environment? tom ---

Hie Tom, First I opened the Anaconda Prompt shell, then i tried to activate the conda in the command line,then i initiated the compas\_fab installation. But i am not able to understand whats the issue!Also is it the issue because of the location of my Anaconda is in D drive and C drive is where Rhino is installed? Aby ---

can you do the following in the Anaconda Prompt and tell me what the result is? ```auto conda activate compas-dev python ``` this should start an interactive Python session (you recognise this by the `>>>`). in that session import `compas` and `compas_fab` ```auto >>> import compas >>> import compas_fab ``` **note** : only type `import compas` and `import compas_fab`, the `>>>` are already there… ---

Hello brgcode, It says no module named compas\_fab found, see the attached image ![Compas%20Fab%20installation%20issue2_%206thAugust2019](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/1a8b5ed7499b03e31ec224e9172d1160b2237cf3.jpeg) ---

okay so that means `compas_fab` is not installed, at least not in the `compas-dev` environment. before debugging anything else, please make sure `compas_fab` is installed in the environment you want to use it from.

I tried installing compas\_fab using Anaconda it works good, but when installing compas\_fab for Rhino I get following issues( as attached in the image). Also in the compas\_fab installation documentation, do you recommend using Anaconda command prompt or the Windows command prompt? As both give different results. The attached image below is using Anaconda command prompt ![Compas%20Fab%20installation%20issue3_%207thAugust2019](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/cd624aba92f29ffb9f0b75cd5589b5534cb4f166.jpeg) ---

On the other hand, if i use Windows Command Prompt i get the following issues ![Compas%20Fab%20installation%20issue4_%207thAugust2019](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/73800bda47c2d43e2eab39e834a72746d666323a.jpeg) ---

Hello Brg, I tried installing the compas\_fab without activating the compas-dev environment. Hence , their was an issue as to why compas\_fab was not installing. Thank you so much. ---

hi, happy to hear it worked. indeed, you have to make sure that the intended environment is active when you install new packages and/or when you install COMPAS packages for Rhino. also, it is important to use the Anaconda Prompt and not the Command Prompt, and to run it **as administrator** to avoid having problems with access rights. tom
