I find it useful sometimes to update all my packages sometimes.
Some might say that it's
stupid dangerous to do so and that I should be cherry picking with care what I want to update and why. But I've never had any issues with that.
Package managers such as
brew have those commands built-in:
# update all your brew packages $ brew update # update all your gems $ gem update
But for some reasons,
pip cannot do that...
To do so you might use the following command, that I stole from rbp on Stackoverflow:
$ pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U
It's quite long to type and even harder to remember. So let's make some aliases that your can add to your
alias pip-update="pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U" alias pip3-update="pip3 freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip3 install -U"
Note the double quotes
" around the command. That's because
grep is using single quotes
' that are not escaped (I find it cleaner/easier to read). I was first getting an error message because of this and it took me a few minutes to figure it out. I'll remember that next time!
