error[E0635]: unknown feature `proc_macro_span_shrink` while building av2 by Pip

eyecod-toppick commented 1 year ago

My python version is 3.8.17. I installed av1 before. When I try to install av2 using pip, I get an error when compiling av2：

      error: could not compile `proc-macro2` (lib) due to 2 previous errors

      For more information about this error, try `rustc --explain E0635`.

  note: This error originates from a subprocess, and is likely not a problem with pip.

I update my Cargo and the problem fixed
