pip install python-cx_Oracle-master.zip 
Processing ./python-cx_Oracle-master.zip

If you're downloading a zip file from GitHub this issue is expected. GitHub does not include the contents of submodules (which is what ODPI-C is to cx_Oracle). You have to download that yourself separately. I don't believe there is anything I can do about that!

rafaelreuber commented 5 years ago

Yes, I downloaded the zip from the Github.

I found the instructions to install using github sources: https://cx-oracle.readthedocs.io/en/latest/installation.html#install-using-github

anthony-tuininga commented 5 years ago

You would need to do the following steps (after your virtual env is activated):

wget https://github.com/oracle/python-cx_Oracle/archive/master.zip
unzip master.zip
cd python-cx_Oracle-master
wget https://github.com/oracle/odpi/archive/master.zip
unzip master.zip
rm -rf odpi
mv -i odpi-master odpi
python setup.py install

If you are able to use the instructions you referenced and clone from GitHub the task is a bit easier. :-)

rafaelreuber commented 5 years ago

It worked. Thank you!

anthony-tuininga commented 5 years ago

You're welcome! Glad to be of help. :-)

error: cx_Oracle.DatabaseError: ORA-12541: TNS:no listener I got this after doing this steps 💯 wget https://github.com/oracle/python-cx_Oracle/archive/master.zip unzip master.zip cd python-cx_Oracle-master wget https://github.com/oracle/odpi/archive/master.zip unzip master.zip rm -rf odpi mv -i odpi-master odpi python setup.py install

what can I do to for that problem

anthony-tuininga commented 4 years ago

You need to check your connect string as the error indicates that there is no listener listening at the location you are telling it to look! Also, please create a separate issue instead of tacking your question on to an old existing one. Thanks.
