Hi everyone,

I’m getting started with compas here, but I haven’t been able to make it past the installation instructions thus far. I’m using conda to install the package, and that runs without hurdles. However, when I try to import the compas\_ghpython module to verify that the installation was successful, I encounter the following error message:

```
>>> import compas_ghpython
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\danhaive\AppData\Local\Continuum\Anaconda3\envs\compas_env2\lib\site-packages\compas_ghpython\ __init__.py", line 17, in <module>
from .utilities import *
  File "C:\Users\danhaive\AppData\Local\Continuum\Anaconda3\envs\compas_env2\lib\site-packages\compas_ghpython\utilities\ __init__.py", line 57, in <module>
from .drawing import *
  File "C:\Users\danhaive\AppData\Local\Continuum\Anaconda3\envs\compas_env2\lib\site-packages\compas_ghpython\utilities\drawing.py", line 37, in <module>
compas.raise_if_ironpython()
**AttributeError: 'module' object has no attribute 'raise_if_ironpython'**

```

Given import compas\_rhino yielded no error, I ran the rhino installation command, but that also returned an error:

> ```
> (compas_env2) C:\>python -m compas_rhino.install   
> C:\Users\danhaive\AppData\Local\Continuum\Anaconda3\envs\compas_env2\python.exe: **No module named compas_rhino.install**
> 
> ```

I looked around the site-packages of my environment, and everything seems to be there, so I’m a little puzzled as to why this isn’t working.  
Has anyone encountered these issues before?

Thanks!

Note that I tried on my laptop, and I was able to install compas successfully. To the best of my knowledge, I did not proceed differently on my desktop.

just to help tracing the source of the problem, could you do the following and report back:

- run Anaconda Prompt as administrator
- activate whatever environment you installed COMPAS in (judging from your posts `compas_env2` ?!)
- start an interactive Python session
- import `compas`
- import `compas_rhino`
- import `compas_ghpython`

in any case, based on the error messages, it seems your problem might be related to the location where Anaconda is installed, which is non-standard (`...\AppData\Local\Continuum\...`) and seems to indicate that you don’t have admin rights to your computer.

we highly recommend to not register Anaconda on `PATH`, to use Anaconda Prompt (“as administrator”) rather than Command Prompt, and to install Anaconda in the standard location: `%USERPROFILE%\Anaconda3`…

keep us posted!
