Decorator module not found

[preshri]

I have installed Selenium2 library with Robot framework and Ride and have configured corresponding Path variables.
I wrote a simple test to open a browser. However on Run i get the foll error. Kindly clarify

preshri,

It looks like you need to install the decorator package, http://pypi.python.org/pypi/decorator/3.3.2. I'm not too familiar yet with windows installations but you can use easy_install, if available, or download the source package, from PyPI and install using python. Both methods are documented on the decorator package PyPI website.

Also with the latest 1.0.0 release of robotframework-selenium2library if you install robotframework-selenium2library using easy_install it should also install the necessary dependencies. - Ed

@preshri how did u install selenium2library?

[Harri]

The same thing happened to me on two different machines, both 64 bit Windows 7 (one Enterprise and one Home Premium)

Steps to reproduce:

1. Install http://www.python.org/ftp/python/2.7.2/python-2.7.2.amd64.msi
2. Install http://code.google.com/p/robotframework/downloads/detail?name=robotframework-2.6.3.win-amd64.exe&can=2&q= or http://code.google.com/p/robotframework/downloads/detail?name=robotframework-2.7rc1.win-amd64.exe&can=2&q= does not matter which one
3. Install https://github.com/downloads/rtomac/robotframework-selenium2library/robotframework-selenium2library-1.0.0.win-amd64.exe
4. Set up PATH env. variables, verify that python and pybot both respond when called from CLI.
5. Create really simple test, no matter what it contains, import Selenium2Library to that
6. Run the test

easy_install does not seem to work with 64 bit Python on Windows (http://pypi.python.org/pypi/setuptools), maybe that is the reason?

[Harri]

Same thing happened when installed 32 bit versions of Python, RF and Selenium2Library.

@emanlove - The "decorator module not found" issue is not seen now after installing the decorator package, however I am displayed the foll error.

@j1z0 - I installed Selenium2 library using the Windows installer "robotframework-selenium2library-1.0.0.win32.exe" and have imported the path to the test suite e.g. D:/py 2.7/Lib/site-packages/Selenium2Library

[j1z0]

the windows installer doesn't package all the dependencies.... we can look into it doing that... the best solution is
pip install Selenium2Library. if you do that it will install all dependencies for you, including selenium, robot framework, decorator and whatever else.

[emanlove]

preshri, so building off of j1z0 comments about the windows install vs. installing using "pip install Selenium2Library", you will need to also install the selenium package.

@j1z0,@rtomac, @Myself - we might need to change the documentation so to reflect this more clearly. Also I thinking we might need a small pip/easy_install tutorial; like how to upgrade or pull a specific version.

[emanlove]

easy_install does not seem to work with 64 bit Python on Windows (http://pypi.python.org/pypi/setuptools), maybe that is the reason? - Herri

Concerning python's packaging tools there are two with very similar names, distutils and Distribute, but with different functionality. Distribute apparently is an upgrade and performs much better across platforms. There currently is an issue with installing robotframework on Linux using buildout (another "python-based configuration-driven build tool") which I am looking into and because it involves python packaging I will see about limitations for Win 64 bit.

[Harri]

In case somebody else is wondering how to get started on Windows (64 bit or not), this is how I got things going:

1. Install http://www.python.org/ftp/python/2.7.2/python-2.7.2.amd64.msi and set that installation directory to your Path env. variable
2. Download http://peak.telecommunity.com/dist/ez_setup.py and run it.
3. Execute easy_install robotframework-selenium2library
4. Set [Python installation dir]\Lib and [Python installation dir]\Scripts to Path env. variable (not sure if this is even necessary, it used to be with RF and SeleniumLibrary)

[elizaleong]

I followed Harri's steps on a 32-bit windows machine. It didn't fix the decorator module error for me, but easy_install (picked up in step 2) came in handy.

My steps and results:

1. installed python-2.7.2 for 32 bit Windows XP
2. downloaded and ran ez_setup.py

In the end I fixed the dependencies by doing:
easy_install decorator
easy_install selenium

Now pybot runs as expected.

[hvelarde]

this issue seems to be caused by an incorrect packaging: you have decorator and selenium listed as dependencies in your setup.py file but there is no requires.txt file inside the EGG-INFO directory of the distribution.

I strongly recommend you to use zest.releaser for this task.

[hvelarde]

you may also take a look at your MANIFEST.in file: it's so complicated that it should be buggy...

[Raptor399]

For completeness sake, I would like to add another use case.

I am using this pom.xml:

            </executions>
        </plugin>
    </plugins>
</build>

Running mvn verify I get the exact same message ImportError: No module named decorator.

In this scenario it is not possible to install extra libraries as discussed above because the Maven plugin will use a prepackaged jython.jar.
