需要注意的是，如果你在使用 NPM 安装包的过程中遇到了任何问题，可以尝试使用 --verbose 参数打印更详细的错误信息，以便更好地诊断问题。例如：
npm install --verbose

原因分析

出现这种错误通常是因为缺少编译环境或者相关依赖包没有正确安装。

问题解决

确保已经安装了 Node.js 和 npm基础上，安装 windows-build-tools。
windows-build-tools 是一个针对 Windows 平台的构建环境自动安装工具，它会自动安装 Visual Studio Build Tools 和 Python 等构建所需的软件包。可以使用以下命令进行安装：

# step1
npm install --global --production windows-build-tools

注意：运行此命令需要管理员权限，如果没有管理员权限，请使用管理员身份打开命令行窗口并再次运行该命令。

Visual Studio Installer
Visual Studio Installer 是一款由 Microsoft 开发的可视化安装程序，它是 Visual Studio IDE 的一部分，旨在为开发人员提供一种方便的方式来选择和安装 Visual Studio 相关的工具和组件。
通过 Visual Studio Installer，用户可以选择需要安装的特定模块，例如 .NET Core 开发、C++ 开发、Web 开发等，并根据自己的需求进行自定义安装。此外，它还提供了强大的配置管理功能，允许用户在多个计算机之间保存和分享安装配置。
除了 Visual Studio IDE 本身，Visual Studio Installer 还可以用于安装其他与 Visual Studio 相关的工具和组件，例如 .NET Framework、SQL Server 数据库、Azure 开发工具等。
总之，Visual Studio Installer 是一个非常实用的工具，它简化了 Visual Studio 工具和组件的安装和管理过程，使开发人员更加高效地进行软件开发。

# step2： 再执行一遍
npm i

2、解析包依赖关系

报错信息:

npm ERR! code ERESOLVE ERESOLVE unable to resolve dependency tree

问题分析

npm ERR! code ERESOLVE 错误通常表示 NPM 在解析包依赖关系时遇到了问题。这个错误可能有很多原因，但通常是因为某些包的版本不兼容导致的。

问题解决

方法一：

清空 NPM 缓存，并重新安装包：

npm cache clean --force
rm -rf node_modules
npm install --force  # 一定是 强制 安装

方法二：

升级 NPM 到最新版本，并重新安装包：

npm install -g npm
rm -rf node_modules
npm install

方法三：

通过手动更改 package.json 文件来解决依赖问题。打开 package.json 文件，在 “dependencies” 或 “devDependencies” 中手动修改版本号以解决依赖问题，然后重新运行 npm install 命令。

方法四：

使用 yarn 代替 NPM 进行包管理，Yarn 的依赖解析算法通常更加健壮。你可以按照以下步骤安装 Yarn ：

npm install -g yarn
