I have seen that, but that did not work in my case. > So either: > > * erase your cache directory. On *nix it's ~/.cache/pip. That would make the usage of cache superfluous and I am wondering if that is really the issue.

For the moment I do in my (tcl) script: while {[catch ${command} errorStr opts]} { incr errors if {${debug}} { puts ------------------------------------------------------------ puts ${opts} puts ------------------------------------------------------------ } if {${errors} >= ${maxTries}} { error "Could not get ${pip} information with ${errors} tries" } } There is not always a problem and if there is a problem it is never more as once. (Till now.) I use command because I do it for pip2 and pip3. It is filled with: # First 2 lines are a header set command {set outdated \ [lrange \ [split [exec ${pip} list --outdated] \n] \ 2 end]} And pip is pip2 or pip3. -- Cecil Westerhof Senior Software Engineer LinkedIn: http://www.linkedin.com/in/cecilwesterhof -- https://mail.python.org/mailman/listinfo/python-list
