问题
I have a python application that's run inside a virtualenv on CentOS. This application needs a python library that's distributed and installed as an rpm. When the application runs I just get
no module named ....
I've verified that the rpm is installed correctly, and I've also installed the rpm in the site-packages directory of the virtualenv but that didn't help. What is the correct way to install an rpm so that an application running in a virtual environment has access to it?
回答1:
By default virtual environments don't access modules in site-packages. You either need to allow such access (toggleglobalsitepackages in virtualenvwrapper) or recreate you virtualenv allowing such access with option --system-site-packages.
回答2:
It also might be a dependency problem. Try to reinstall the RPM using yum instead of rpm:
yum -y reinstall /path/to/your/file.rpm
