I am using a third party python module in my code and i need to install that module using easy_install in my local/current directory.
I have to write a shell script which will export PYTHONPATH then do easy_install on that path ,then after executing this script i run my python script which will import that module.
However,I can not persist the PYTHONPATH set from the script after the script is done executing and hence import fails.
My script looks like this:
export PYTHONPATH="$HOME/final/dnsserver/Local/lib/python2.7/site-packages"
easy_install --prefix=$HOME/final/dnsserver/Local pygeoip
How can I make sure that the path will be setand exported even after script is done.
P.S. I do not have root access on this machine

I have a python script that processes excel files. I this script is run via python from the command line, it runs as expected but when I run from incron, it does't appear to see my imports, such as pandas
this is how I call from incron:
file/to/monitor IN_CREATE,IN_MOVED_TO /usr/bin/sh /my/main/shell/script
this is how my script looks like
#!/usr/bin/env python
source activate my_env
python /absolute/path/to/python/script
and now as I check on the logs, from abrt,
step1.1_executeConsolidation.py:2::ImportError: No module named pandas
I'm thinking this is just an environment issue with incron, but I'm not sure how to set it up properly.
I use anaconda by the way. If run manually, I don't have any library dependency issues
I have Python 2.7 installed at C:\Python27 and I have added the path C:\Python27\; to the environment variables and .py: to PATHEXT. I am able to launch Python.
I downloaded a folder google-python-exercises to my desktop, which contains a script hello.py.
Following the advice in the Google Developers course, I try to run the script by using python hello.py at the command prompt.
When I attempt this, I get the message: python: can't open file 'hello.py: [Errno 2] No such file or directory. What is wrong, and how am I supposed to fix it? I found that I can solve the problem by running cmd from the folder, but this seems like a temporary solution.
Python cannot access the files in the subdirectory unless a path to it provided. You can access files in any directory by providing the path. python C:\Python27\Projects\hello.py
I resolved this problem by navigating to C:\Python27\Scripts folder and then run file.py file instead of C:\Python27 folder
Options include:
Run the command from the folder where hello.py is located (this way, hello.py is already a relative path to the file). This is the solution that OP found.
Give a proper path to the hello.py file - either absolute (e.g. C:/Users/me/Desktop/google-python-exercises/hello.py) or relative (for example, google-python-exercises/hello.py, if the current working directory is the desktop).
Add a path to the folder (C:/Users/me/Desktop/google-python-exercises) to the PYTHONPATH environment variable, and run the code as a module (python -m hello).
In all cases, a path is being given directly - Python will not "search" for the file.
From your question, you are running python2.7 and Cygwin.
Python should be installed for windows, which from your question it seems it is. If "which python" prints out /usr/bin/python , then from the bash prompt you are running the cygwin version.
Set the Python Environmental variables appropriately
, for instance in my case:
PY_HOME=C:\opt\Python27
PYTHONPATH=C:\opt\Python27;c:\opt\Python27\Lib
In that case run cygwin setup and uninstall everything python.
After that run "which pydoc", if it shows
/usr/bin/pydoc
Replace /usr/bin/pydoc
with
#! /bin/bash
/cygdrive/c/WINDOWS/system32/cmd /c %PYTHONHOME%\Scripts\\pydoc.bat
Then add this to $PY_HOME/Scripts/pydoc.bat
rem wrapper for pydoc on Win32
#python c:\opt\Python27\Lib\pydoc.py %*
Now when you type in the cygwin bash prompt you should see:
$ pydoc
pydoc - the Python documentation tool
pydoc.py <name> ...
Show text documentation on something. <name>
may be the name of a Python keyword, topic,
function, module, or package, or a dotted
reference to a class or function within a
module or module in a package.
...
Try uninstalling Python and then install it again, but this time make sure that the option Add Python to Path is marked as checked during the installation process.
I'm trying to setup regular backups of rethinkdb, but keep running into issues. How do you setup rethinkdb-dump to run from cron?
Here is my script:
$ cat backup.sh
#!/bin/bash
NOW=$(date +"%Y-%m-%d-%H-%M")
/usr/bin/rethinkdb dump -e my_db -f /root/db_backup/$NOW.tar.gz
The script runs just fine when I run it manually. However, when try and run it from cron it doesn't work and I get the following at stderr:
Error when launching 'rethinkdb-dump': No such file or directory
The rethinkdb-dump command depends on the RethinkDB Python driver, which must be installed.
If the Python driver is already installed, make sure that the PATH environment variable
includes the location of the backup scripts, and that the current user has permission to
access and run the scripts.
Instructions for installing the RethinkDB Python driver are available here:
http://www.rethinkdb.com/docs/install-drivers/python/
It appears to be a Python environment issue, but I cannot figure out how to make it happy... thoughts? Help!
When you run it from that backup.sh script, it maybe run without correct PATH setup and cannot found the PATH of rethinkdb-dump.
First, let find out where is rethinkdb-dump
which rethinkdb-dump
(on my pc, I guess it's very different on your pc)
/usr/local/bin/rethinkdb-dump
Now, try to append the PATH to your script backup.sh
#!/bin/bash
export PATH="$PATH:/path/to/folder/contain-rethinkdb-dump"
# The rest of your script normally
So take my example, I will put it like this:
export PATH="$PATH:/usr/local/bin"
I think your rethinkdb-dump live outside normal bin folder (/usr/bin, /usr/local/bin etc)
The python installer for windows installs scripts and packages in subfolders here:
$env:APPDATA\Python\Python37 for powershell
%APPDATA%\Python\Python37 for cmd
cd this directory to see /Scripts and /site-packages (pip packages)
I'm working on a project for which I need to a module. I want to know how to import some other module in python that is not installed.
When I write
import xaut
It gives error no module named xaut.
I have xaut-0.4.5 that I downloaded from following link.
Please help me how to use it.
Well I think following will help
Extract your zip file
Open the command line (a linux terminal or cmd on windows). I am on linux so I have a terminal.
Now enter the directory that you have extracted.
In it is a directory "python" cd into it.
If you run the ls command (if on windows run dir) you will see that in this directory there is a script "setup.py". We need to execute it for installation.
Execute this script by giving command python setup.py install
This will hopefully install it and then you would be able to import it.
Basically you have only downloaded the package. To make a package work you also need to install it. So when you download a package always search for a setup.py file.
This is certainly a duplicate question. You can look up how to add a python module to the path in windows.
here is an example
How to add to the pythonpath in windows 7?
I want to be able to run a python script at the command line using Enthought Canopy, but I don't want to specify the full path to the script.
As I see it, there are two options.
Option 1: Make the python script an executable, add #!/usr/bin/env python to the top of the script, and put the directory containing the script on my $PATH. Now I can execute the script like this:
$ run.py
Option 2: As suggested by Andrew Clark in another SO post, just put the directory containing the script on my $PYTHONPATH. Then I can execute the script like this:
$ python -m run.py
The -m causes python to search the $PYTHONPATH.
I prefer Option 2, and it works fine with the system python on my mac (v2.7.2), but I cannot get it to work with Enthought Canopy. I can load Canopy python and import modules in the same directory as run.py, so I know that I have the path correct. I just cannot execute the script from the command line. Is this a bug or am I doing something wrong?
BTW, it's probably a typo, but just to make sure you should be using the module name, not the file name, with the -m option. For example, python -m run
If that is not the problem then make sure that the python that is used in your option 2 is the python located in your Canopy User virtual environment. You can use the which command to verify that. For example:
$ which python
/Users/YourUserId/Library/Enthought/Canopy_64bit/User/bin/python
If that is not what you get then you can either add that bin folder to the beginning of your PATH environment variable, or you can activate that virtual environment like this:
source /Users/YourUserId/Library/Enthought/Canopy_64bit/User/bin/activate
