In case this is of interest to anyone  I had the same problem when I was running Python in Cygwin  in my case it was complaning that pandas wasn t installed even though it was  The problem was that I had 2 installations of python - one in windows and another one in cygwin  using the cygwin installer  and although both were the same versions of Python  the Cygwin installation was confused about where Pandas was installed  When i uninstalled cygwin s Python and pointed Cygwin at the windows installation everything was fine

My usual trick is to simply print sys path in the actual context where the import problem happens  In your case it d seem that the place for the print is in  home hughdbrown  local bin pserve   Then check dirs  amp  files in the places that path shows    You do that by first having   import sys   and in python 2 with print expression   print sys path   or in python 3 with the print function   print sys path

If you have a script with the same name as your module in another directory  it will use that instead  For example   module py  module    --module          --  init   py     --module py   This will make it so that the first module py is being used  not the second one

I ve had this problem too  I had just forgotten to type workon myproject in the terminal before executing my program

I had the same issue  I solved it by running the command in a different python version  I tried python3 filename py  Earlier i was using Python 2 7   Another possibility is that the file from which something is imported may contain BOM  Byte Order Mark   It can be solved by opening the file in some editor which supports multiple encoding like VSCode  Notepad    and saving in a different encoding statndard like ANSI  UTF-8 without BOM

They are several ways to run python script    run by double click on file py  it opens the python command line  run your file py from the cmd prompt  cmd   drag drop your file on it for instance  run your file py in your IDE  eg  pyscripter or Pycharm    Each of these ways can run a different version of python         Check which python version is run by cmd  Type in cmd   python --version      Check which python version is run when clicking on  py    option 1   create a test py containing this    import sys print  sys version  input  exit     Option 2    type in cmd   assoc  py ftype Python File     Check the path and if the module  ex  win32clipboard  is recognized in the cmd   create a test py containing this    python import sys sys executable sys path import win32clipboard win32clipboard   file     Check the path and if module is recognized in the  py  create a test py containing this   import sys print sys executable  print sys path  import win32clipboard print win32clipboard   file      If the version in cmd is ok but not in  py it s because the default program associated with  py isn t the right one  Change python version for  py  To change the python version associated with cmd   Control Panel All Control Panel Items System Advanced system setting Environnement variable In SYSTEM variable set the path variable to you python version  the path are separated by    cmd use the FIRST path eg  C  path to Python27 C  path to Python35   cmd will use python27   To change the python version associated  with  py extension   Run cmd as admin   Write  ftype Python File  C  Python35 python exe    1     It will set the last python version  eg  python3 6   If your last version is 3 6 but you want 3 5 just add some xxx in your folder  xxxpython36  so it will take the last recognized version which is python3 5  after the cmd remove the xxx    Other    No modul error  could also come from a syntax error btw python et 3  eg  missing parenthesis for print function         Thus each of them has it s own pip version

The PYTHONPATH is not set properly  Export it using export PYTHONPATH  PYTHONPATH  path to your modules

User · Answer

I set the PYTHONPATH to     and that solved it for me   export PYTHONPATH       For a one-liner you could as easily do   PYTHONPATH     your python script   These commands are expected to be run in a terminal

I met the same problem  and I try the pdb set trace   before the error line    My problem is the package name duplicate with the module name  like   test  --   init   py  -- a         --   init   py         -- test py  -- b      --   init   py   and at file a   init   py  using from test b import xxx will cause ImportError  No module named b

I had the same problem  and I solved it by adding the following code to the top of the python file   import sys import os  sys path append os path dirname os path dirname os path dirname   file         Number of repetitions of os path dirname depends on where is the file located your project hierarchy  For instance  in my case the project root is three levels up
