问题
I just started working with anaconda. Earlier I was working with Python 2.7 on my system. I was writing a script for devices connected to my laptop via usb. For this, I needed the usb module/package. I initially tried doing in Python 27. I installed using:
easy_install libusb1
The output with this is ( screenshot is also there) :
Searching for libusb1
Best match: libusb1 1.4.0
Processing libusb1-1.4.0-py3.4.egg
libusb1 1.4.0 is already the active version in easy-install.pth
Using c:\users\eku\anaconda3\lib\site-packages\libusb1-1.4.0-py3.4.egg
Processing dependencies for libusb1
Finished processing dependencies for libusb1
C:\users\eku\anaconda3\ : this is the path according to my system whose name is eku.
Installing with pip shows an error unknown command libusb1
Because I have installed the package before, the screenshot shows the correct result that the package is already installed. But the locatio is where my anaconda's site-packages are there.
Why is this occurring and how should I correct this. I want to keep both anaconda and the other 2.7 version separate. (If this has something to do with path variable, then yes I am confused about the same).
As can be seen from the above output the libusb gets installed in in anaconda, I tried running the same code in Spyder (in anaconda). When I write,
import usb1
I get the error:
ImportError: No module named 'usb1'
Why is this happening?
My spyder got installed with anaconda itself. I simply click on its icon and the workspace launches. Nothing more I had to do, it started working and even my other files are working fine.
Thanks!

I know it's a bit after the fact, but I had the same issue. I ended up searching my registry (I used a program called RegistryFinder, there are likely others) and finding that there was a registry value pointing to the Anaconda install directory. I deleted it and I was able to install things to my normal Python directory. I had previously uninstalled Anaconda and wasn't worried about having references to it, so you may want to save off those values.
