Correct way to put libraries in site-package folder?

[Jaison Raj]

Hi, 

I am trying to create a binary application (after compiling and packaging from windows).

In my controller, i am importing a library :"import xml.etree.cElementTree as ET".

I placed the files cElementTree.py and cElementTree.pyc in etree folder as follows:

\web2py\site-packages\xml\etree.

I am getting error: 

<type 'exceptions.ImportError'> No module named cElementTree.

How can i solver this error?

Pls advice.

Regards,

Jaison

Do you have empty __init__.py files inside those two subfolders?

Hi Anthony,

Yes i have empty __init__.py files in each folders.

I tried to use "import xml.etree.ElementTree as ET". (instead of cElementTree) it works.

Now i am having problem importing another library: Plotly

the trace back as follows;

Traceback

1. 2. 3. 4. 5. 6. 7. 8.

Traceback (most recent call last): File "D:\2.

I even copied everything from my C:\Python27\Lib\site-packages to. ... web2py\site-packages, still no luck. Is web2py binary limited to import certain type of libraries only? Please advise. Regards, Jaison

You can only use the web2py binary with the prepackaged libraries and some pure python packages.

If you need to use thrd party libraries that may come to binary form, you should use the regular source version of web2py.
