Dependency conflict using serde with chrono together

[kivimango]

Hello !
I have a project that depends on chrono.If i add the serde dependency with the derive feature, cargo check fails with:

error: failed to select a version for `syn`.
    ... required by package `serde_derive v1.0.152`
    ... which satisfies dependency `serde_derive = "=1.0.152"` of package `serde v1.0.152`
    ... which satisfies dependency `serde = "^1.0.145"` (locked to 1.0.152) of package `serde_spanned v0.6.1`
    ... which satisfies dependency `serde_spanned = "^0.6.1"` (locked to 0.6.1) of package `toml v0.7.2`
    ... which satisfies dependency `toml = "*"` (locked to 0.7.2) of package `twin-commander v0.1.0`
versions that meet the requirements `^1.0.104` are: 1.0.109, 1.0.108, 1.0.107, 1.0.106, 1.0.105, 1.0.104

all possible versions conflict with previously selected packages.

  previously selected package `syn v1.0.103`
    ... which satisfies dependency `syn = "^1.0.95"` (locked to 1.0.103) of package `cxx-build v1.0.82`
    ... which satisfies dependency `cxx-build = "^1.0.34"` (locked to 1.0.82) of package `iana-time-zone-haiku v0.1.1`
    ... which satisfies dependency `iana-time-zone-haiku = "^0.1.1"` (locked to 0.1.1) of package `iana-time-zone v0.1.53`
    ... which satisfies dependency `iana-time-zone = "^0.1.44"` (locked to 0.1.53) of package `chrono v0.4.23`
    ... which satisfies dependency `chrono = "*"` (locked to 0.4.23) of package `twin-commander v0.1.0 `

failed to select a version for `syn` which could resolve this conflict

Could you update the syn crate ? or provide a serde version that works with crhono together? Thank you.

That seems odd. We support the latest syn, so it must be something else restricting the dependency. Have you tried running cargo update?

After running cargo update the project now compiles., thank you.
