虚拟环境中的pip安装问题？？货物，即锈蚀软件包管理器，未安装或不在路径上。

Question

我正在使用python虚拟环境来处理一个项目。在设置了an并从git中提取后，我尝试了pip install -r requirements.txt，但下面出现了一个错误。

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
  error: subprocess-exited-with-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/

      Checking for Rust toolchain....
      [end of output]

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

× Encountered error while generating package metadata.

我正在使用PythonVersion3.10.2，PIPVersion22.0.4。

知道怎么解决这个问题吗？我安装了铁锈，但没有修复。

在将虚拟环境移到本地后，我不会收到下面的错误。

Answer 1

面临着类似的问题。在安装了64位版本的python之后，一切都很好。

Answer 2

以上错误是由生锈包造成的。

pywinpty

您所需要做的就是从requirements.txt文件中删除它并重新部署您的应用程序。
