Sifat mengikat 'FieldAttr:ToTokens' tidak berpuas hati: ralat

Question

Saya mahu menggunakan versi Dockerfile pada EC2(fargate). Saya mendapat ralat berikut dalam cloudwatch. "Gagal membuat kumpulan.: Ralat (Tiada)" Saya telah mencari penyelesaian untuk masalah ini. Saya menukar kaedah daripada build 更改为 build_unchecked semasa membuat sambungan.

Walau bagaimanapun, saya mendapat ralat berikut dan tidak dapat menyusun.

Saya cuba lulus melalui rujukan tetapi tidak berjaya.

Bina fail Docker lain tanpa pengubahsuaian. Masalahnya adalah dalam Dockerfile.

Answer 1

Hei, saya baru sahaja mengalami ralat yang sama dengan mengemas kini kebergantungan ini:

https://github.com/nxthat/nanocl/commit/6b7b19d7ff50d9392b1e56ec1ad67c34ea63 c632

Mungkin anda boleh membetulkannya dengan cepat dengan menurunkan taraf beberapa kebergantungan?

Saya pun nak tahu apa masalahnya

Answer 2

Saya rasa ini berlaku kerana perubahan besar dalam "rujukan" Pautan soalan
