Could not compile dependency :ecto_sql, "mix compile" failed
I have raised an issue at ecto_sql issue_link
Adding it here to reach out to larger community.
I have updated my ecto_sql_3.0 to ecto_sql_3.4 and now I am unable to run my application like I used to do
using mix phx.server
I am getting the following error
** (CompileError) lib/ecto/adapters/postgres/connection.ex:309: Ecto.Query.WithExpr.__struct__/0 is undefined, cannot expand struct Ecto.Query.WithExpr
(stdlib) lists.erl:1354: :lists.mapfoldl/3
(stdlib) lists.erl:1355: :lists.mapfoldl/3
could not compile dependency :ecto_sql, "mix compile" failed. You can recompile this dependency with "mix deps.compile ecto_sql", update it with "mix deps.update ecto_sql" or clean it with "mix deps.clean ecto_sql"```
Can you please help me out here?First Post!

For it it helped so simply remove the deps and _build folder with rm -rf _build deps and fetch the dependencies again with mix deps.get
