Spyder start: the "pydicom" distribution was not found and is required by spyder

[matthew...@daf.qld.gov.au]

Hi All Spyder Gurus,

I wiped my Win7 machine a little while ago and had to re-install pythonxy.

Spyder will no longer start. trying to run it from Python27\Scripts\spyder

yields the following:

c:\>\Python27\Scripts\spyder

Traceback (most recent call last):

  File "c:\Python27\Scripts\spyder-script.py", line 5, in <module>

    from pkg_resources import load_entry_point

    raise DistributionNotFound(req, requirers)

pkg_resources.DistributionNotFound: The 'pydicom' distribution was not found and

 is required by spyder

Any ideas how to fix this behaviour and get spyder running?

Thanks

Just want to +1 this, I'm having the same problem on Windows 8.1.  Very frustrating!

I actually managed to fix this, by using easy_install to reinstall pydicom; it then wanted me to install sympy; after that, it seems to be working!

Hi Beth, I'm having the exact same problem, but I don't understand wha tyou mean by using easy_install to install pydicom?? ANY help would be great!!

[Beth Cimini]

Download and install this, then (on Windows at least) all you need to do is open the command prompt and type (without quotes) "easy_install pydicom" or "easy_install sympy" and it'll download and install just about any python package. Pip is another python installer that may work for your purposes.

Good luck!

I had the same issue on Windows 8.1, and this solution worked without a glitch :D 

Thank you Beth!

BRILLIANT! Thank you Beth! Worked perfectly (after running "easy_install sympy" not just pydicom)
