在虛擬環境中安裝 pip 的問題 - Cargo，Rust package 管理器，未安裝或不在 PATH 上

Question

我正在使用 python 虛擬環境來處理項目。 設置我的 venv 並從 git 拉出后，我嘗試pip install -r requirements.txt但在下面出現錯誤。

Collecting orjson==3.5.2
  Using cached orjson-3.5.2.tar.gz (740 kB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... done
  Preparing metadata (pyproject.toml) ... error

  × Preparing metadata (pyproject.toml) did not run successfully.

      Cargo, the Rust package manager, is not installed or is not on PATH.
      This package requires Rust and Cargo to compile extensions. Install it through
      the system's package manager or via https://rustup.rs/

      [end of output]

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

我正在使用 Python 版本 3.10.2、pip 版本 22.0.4。

知道如何解決這個問題嗎？ 我安裝了 rust 但沒有修復。

將我的虛擬環境移動到本地后，我沒有收到以下錯誤。

Answer 1

面臨類似的問題。 安裝 64 位版本的 python 后一切正常。

Answer 2

上面的錯誤是由一個rust package引起的

pywinpty

您需要做的就是將其從 requirements.txt 文件中刪除並重新部署您的應用程序。
