Difficulty installing python modules after installing anaconda
Question: 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!


Answer: 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.
