Running on Ubuntu 16.04, Python 3.6.2
I have successfully used this package before. In fact, it works on a different pc but not the one I need it to work on.
https://pypi.python.org/pypi/pandas_access
import pandas_access as mdb
df = mdb.read_table("myDatabase", "myTable")

The code for pandas_access is available here

It's supposed to only require MDB Tools which I have installed and it works. I can open the access database using MDB Tools on its own.
Solved!
I ran mdb-schema on the command line of the working pc and got:
Usage: mdb-schema [options] []
where options are:
-T Only create schema for named table
-N Prefix identifiers with namespace
I rant mdb-schema on the non-working pc and got:
The program 'mdb-schema' is currently not installed. You can install it by typing:
sudo apt install mdbtools
Not sure how I this wasn't installed as I was running gmdb2 on it for sure before this but oh well, need to move on.

While trying to run a python script on EC2 (running ubuntu), I'm getting this error:
Traceback (most recent call last):
File "128d.py", line 9, in <module>

raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'python': 'python'
All the dependencies are installed. I've tested the script on my home machine (Windows 10), and it works just fine. I can see that something is wrong with python installed on the EC2 machine, probably. But I didn't manage to find an answer on the web.
I've fixed the problem.
Turns out, I had my python installed in a folder that was named python3. So, when the suprocess.py file tried to find python in path, it wasn't there.
I've renamed python3 in /usr/bin/ to python and the problem is fixed.
P.S. However, keep in mind, that it might raise some other issues. When I tried to aws s3 cp, it was looking for python3 instead. Maybe adding another copy of that folder as python3 would help.
I'm extremely new to Python, so sorry if this is a stupid question. Anyways, I'm getting this error when trying to run a package I installed on PyCharm (Python IDE):

From what I've gathered from previous questions, it seems this is because I don't have gmsh in my virtualenv. Now that I've downloaded gmsh, I can't find a proper installation guide on how to get it into the virtualenv. Does anyone have experience with this?
I guess more specifically, is there a way I can pinpoint the path that it's trying to access and just paste gmsh into that directory?
openbte\geometry.py seems to run gmsh.exe without any path:
a=subprocess.check_output(['gmsh','-' + str(self.dim),'mesh.geo','-o','mesh.msh'])
Which means it expects gmsh.exe somewhere in the %PATH%. So install gmsh and add the directory with gmsh.exe to the %PATH%.
My python version is 2.7. I tried to install pyjags using pip install pyjags but got such error:

I just deployed a python package and had same errors when I tried to install via pip. Turns out the main reasons was that the project artifacts (static files, etc) were not included in the MANIFEST file or it couldn't load a file path. I think you might want to consult the documentation here.
The line below was copied from the docs:
The setup.py script uses pkg-config to locate the JAGS library. If JAGS is installed in some non-standard location, then you may need to configure pkg-config to pick up correct metadata file. For example, if JAGS have been configured with --prefix=/opt/, then JAGS metadata file would be located in /opt/lib/pkgconfig/. This path can be included in pkg-config search path as follows:
export PKG_CONFIG_PATH=/opt/lib/pkgconfig/:$PKG_CONFIG_PATH
From your track trace, it seems like you failed to configure that.
pip is not a supported installation method. Read the installation instructions on the website enter link description here.
EDIT2: OK this is weird. (I can't answer my own question, so I just put it as another edit to the question. I think it has something to do with the fact that I tried to do this installation within a Dropbox-synced directory. I got this to work on my Desktop. Can anyone explain why this is the case?
Original question:
I'm trying to do Heroku's Python setup tutorial (http://devcenter.heroku.com/articles/python), on my Mac OS X (Lion), but I get caught up with the step of creating a virtualenv.
So what I did was this in the command line (not using sudo caused permissions error):
sudo pip install virtualenv
But then, when I do "virtualenv venv --distribute" (I also tried with sudo), I get the following error:
New python executable in venv/bin/python
Installing distribute..............................................................................................................................................................................................................................................................................................done.
Installing pip...
Error [Errno 2] No such file or directory while executing command /Users/AndyFang/Drop...env/bin/easy_install /Library/Python/2.7/...pport/pip-1.1.tar.gz

Not really sure what to do. It seemed like I didn't have easy_install on my Mac, but I do have it... I'm not sure what the deal is?
EDIT: I also just tried installing virtualenv with easy_install, but I get the exact same error.
If your problem is the same as mine, then it's because there's a space somewhere in the path to your Dropbox-synced folder.
Virtualenvs aren't portable, so you can't keep them synced across multiple machines if the paths don't match up.
In general, it's a bad idea :)
I've been trying to get TurboGears installed on Windows by following this site.
I've installed virtualenv but when I execute the command "virtualenv --no-site-packages testproj", I get the following message:

Can someone help me debug this ? If any one knows a better tutorial to install turbogears, please let me know.
I figured out the error. Apparently, virtualenv does not like it if folder names have spaces (eg Documents and Settings). It worked fine when my folder names had no spaces.
