pip 无法安装 Scipy（或任何东西）(Python 3.10)
pip unable to install Scipy (or anything) (Python 3.10)
我一直在尝试下载一个名为 simpful 的库。但我刚刚开始 python，我想我缺少一些非常基本的东西。我在网上搜索某种解决方案很长时间了，但对我来说还没有任何效果。我还没有用 pip 下载任何东西 before.pip 版本是 21.3 和 python 3.10。我知道它的公正和错误日志，但也许有人能认出它。

一直到栈底错误：
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
所以你需要安装Microsoft VS C++ build tools。

建议创建一个隔离的虚拟环境，
c:\MY_PROJECT_FOLDER> py -m venv venv
c:\MY_PROJECT_FOLDER> venv\Scripts\activate
(venv) c:\MY_PROJECT_FOLDER> pip list
(venv) c:\MY_PROJECT_FOLDER> pip install simpful
非常基本，但显然是由于 Python 安装了两次造成的。
正在安装Scipy
SciPy 是一个免费的开源 Python 库，其中包含针对科学和技术计算优化和开发的软件包。如果你安装了 Python，你可以使用 Python 的标准 pip 包管理器，并从 Python 包索引安装它。在某些 Linux 发行版中，您可以使用系统的本机包管理器执行系统范围的安装。
第 1 步：确保检查您正在使用的 Python 版本
python -V
第二步：确保pip正常工作并且在python安装过程中安装（Python 2.7以上版本自带pip安装）
where pip
第三步：检查安装的pip是否更新
python -m pip install -U pip
第 4 步：检查是否安装了 numpy，因为 Scipy 有一个 numpy 依赖项。如果不安装 numpy
pip install numpy
第五步：安装scipy
pip install scipy
我一直在尝试下载一个名为 simpful 的库。但我刚刚开始 python，我想我缺少一些非常基本的东西。我在网上搜索某种解决方案很长时间了，但对我来说还没有任何效果。我还没有用 pip 下载任何东西 before.pip 版本是 21.3 和 python 3.10。我知道它的公正和错误日志，但也许有人能认出它。

一直到栈底错误：
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
所以你需要安装Microsoft VS C++ build tools。

建议创建一个隔离的虚拟环境，
c:\MY_PROJECT_FOLDER> py -m venv venv
c:\MY_PROJECT_FOLDER> venv\Scripts\activate
(venv) c:\MY_PROJECT_FOLDER> pip list
(venv) c:\MY_PROJECT_FOLDER> pip install simpful
非常基本，但显然是由于 Python 安装了两次造成的。
正在安装Scipy
SciPy 是一个免费的开源 Python 库，其中包含针对科学和技术计算优化和开发的软件包。如果你安装了 Python，你可以使用 Python 的标准 pip 包管理器，并从 Python 包索引安装它。在某些 Linux 发行版中，您可以使用系统的本机包管理器执行系统范围的安装。
第 1 步：确保检查您正在使用的 Python 版本
python -V
第二步：确保pip正常工作并且在python安装过程中安装（Python 2.7以上版本自带pip安装）
where pip
第三步：检查安装的pip是否更新
python -m pip install -U pip
第 4 步：检查是否安装了 numpy，因为 Scipy 有一个 numpy 依赖项。如果不安装 numpy
pip install numpy
第五步：安装scipy
pip install scipy
