python - 错误：安装 requirements.txt 时命令出错，退出状态为 1

问题描述

我一直在尝试从 requirements.txt 文件安装软件包，但出现错误。我创建了一个虚拟环境来安装软件包，但得到了他的巨大阵列。我的机器在 python 3.8 上运行

以下是我尝试在虚拟环境中安装 requirements.txt 文件时在终端中遇到的错误

解决方案

尝试隔离哪一行 requirements.txt 给你一个错误，你可以尝试注释掉 torch 看看没有它的安装是如何进行的。

要复制您的错误消息，请尝试 pip install torch，我认为它会给您您遇到的错误消息。

之后有两件事：

  • 转到 torch 文档，了解手动安装
  • 尝试使用另一个包管理器 conda 安装

此外，如果大多数库都在那里，您可能需要安装 Anaconda 软件包来尝试。

作为旁注 - 安装一些重度依赖项的糟糕体验经常发生，所以把它当作练习，这不是你做错了什么，这是你尝试使用的依赖项的一种性质。祝你好运！
