Question

Hi I am trying to upgrade to pants `2 11` from `1 30` I got a lot of errors like this ```Name python library is not defined ``` What should I change them to

That s a pretty big jump have you looked at this I think `python library` turned into `python sources` but maybe it s safer to take a read through the upgrade tips and even going so far back as the upgrade tips from 1 30 gt 2 0

freezing-area-97131 · Answer

Yep but some people suggested me directly jump to 2 11 and I don t see any instruction about how to update the python library in that page

wide-midnight-78598 · Answer

Personally I would go from 1 30 to 2 0 0 and then jump a bunch of versions at a time

freezing-area-97131 · Answer

Ok I will try that

I got this now ``` MappingError Failed to parse xxx xxx BUILD call got an unexpected keyword argument name ``` Is this about `python requirement library`

hundreds-father-404 · Answer

yeah that can t have `name=` but it shouldnt if youre on 1 30

see <https www pantsbuild org v2 4 docs how to upgrade pants 2 0>

hundreds-father-404 · Answer

Thx It s a long journey I m almost there Still need helps from you guys

freezing-area-97131 · Answer

You mean in 1 30 it has already not accepted `name` but when I ran ` pants filedeps gt dev null` on `1 30` it didn t complain anything

hundreds-father-404 · Answer

yeah `name` only works w 2 10+ It sounds like you partially were trying to use 2 11 I recommend going back to your stable 1 30 branch and starting the 2 0 upgrade from there without the changes from 2 11

happy-kitchen-89482 · Answer

I was the person who recommended going from 1 30 to 2 11 just because 1 30 gt 2 is already a big leap so why not just leap all the way there

happy-kitchen-89482 · Answer

Going one at a time from 2 0 to 2 11 seems unnecessary

happy-kitchen-89482 · Answer

Maybe I was giving bad advice

freezing-area-97131 · Answer

Lol Don t be You help me a lot

freezing-area-97131 · Answer

I think I kind of successfully upgrade to 2 0 but I have jvm and thrift in my project so I have to ignore those files for now < hundreds father 404> It seems that the `name` issue happen when I upgrade from 2 0 to 2 1

hundreds-father-404 · Answer

Benjy if you want to keep old build files still working that is too big of a jump

hundreds-father-404 · Answer

gt < hundreds father 404> It seems that the name issue happen when I upgrade from 2 0 to 2 1 Hm so are you able to get 2 0 working well That would be probably good to land as a PR so that you have a baseline

hundreds-father-404 · Answer

you re getting this ``` MappingError Failed to parse xxx xxx BUILD call got an unexpected keyword argument name ``` If you are able to share the build file it might be easier to help

freezing-area-97131 · Answer

Good news I have already made it to 2 10

freezing-area-97131 · Answer

Now I have to deal with jvm scala and thrift

happy-kitchen-89482 · Answer

I don t think it s necessarily desirable to keep old BUILD files working for example you can delete almost all your `dependencies=` now

happy-kitchen-89482 · Answer

And it may be easier to let ` pants tailor` generate BUILD files for you

happy-kitchen-89482 · Answer

this was a reply to Eric

happy-kitchen-89482 · Answer

That is good news Note that Pants 2 x infer dependencies automatically from your import statements so you can remove a lot of explicit `dependencies` from your BUILD files
