【中文标题】为啥运行“pip install -r requirements.txt”时出现错误“找不到满足要求 scipy==1.5.3 的版本”？【英文标题】：Why do I get error "Could not find a version that satisfies the requirement scipy==1.5.3" when running "pip install -r requirements.txt"?为什么运行“pip install -r requirements.txt”时出现错误“找不到满足要求 scipy==1.5.3 的版本”？ 【发布时间】：2021-04-30 04:46:23 【问题描述】：我正在尝试为现有的 Django 项目安装所有需要的模块。当我运行pip install -r requirements.txt 时，出现以下错误：
ERROR: Could not find a version that satisfies the requirement scipy==1.5.3
ERROR: No matching distribution found for scipy==1.5.3
我正在运行 Python 3.9.1。为什么会出现这些错误？
这是我可以从输出中包含的尽可能多的内容：

【问题讨论】：
我认为 Python 3.9.1 和 Windows 操作系统没有预编译的scipy1.5.3。这意味着必须从源代码构建 scipy，这需要 C/C++ 编译器和一些数值计算库。构建 scipy 很难（对我来说），所以我会尝试使用 pip install scipy==1.5.3 的早期 Python 版本。
@YangYushi 我明白了，那么早期的 Python 版本可以工作吗？如果是这样，我会尝试安装 Python 3.8。谢谢！
是的，Python3.8 应该可以工作。 This link列出了所有“支持的python”
您需要安装visual sutdio安装程序。
【参考方案1】：
在你的 requirements.txt 里面用这个改变 scipy 行 scipy==1.6.0 并保存。 现在重试 pip 安装。
【讨论】：
【参考方案2】：我改为安装 Python 3.8。它与 Python 和 scipy 版本之间的不兼容有关。之后就成功了。
【讨论】：
以上是关于为啥运行“pip install -r requirements.txt”时出现错误“找不到满足要求 scipy==1.5.3 的版本”？的主要内容，如果未能解决你的问题，请参考以下文章
