Greenlet on Old Systems
I ran into an issue when trying to set up a Docker container for Plivo; this
has to do mostly with
greenlet on old systems as well as any packages such as
gevent which rely on this.
More specifically, for Python 2.7.3 and older only, projects requiring
greenlet may throw an error on attempting to run them
_PyTrash_thread_deposit_object was not defined in those versions.
This specifically affected me since Plivo requires
libgnutls-dev, which is
not present in the default
debian:jessie or newer base Docker images... using
debian:wheezy, though, only gives us Python 2.7.3. Fortunately, this is
fixeable without installing anything from non-standard sources!
The issue arises when we
pip install greenlet (or
pip install PACKAGE,
PACKAGE relies on
gevent). The simple fix for this is
to make sure we don't install the broken
Specifically for Plivo, modifying the
plivo_install.sh script with the above
change is enough to let us start Plivo with no issues.
