简介： 这篇文章分享了作者在运行前端Vue项目时遇到的关于Python执行环境的问题和解决方法。问题是由于找不到Python可执行文件导致的编译错误，解决方法包括安装编译环境、卸载并重新安装出现问题的`node-sass`包，并重新执行`npm install`和`npm run dev`。

今天跑公司新项目的时候、运行前端vue、报了一个关于python的错误。就离谱

2、问题核心部分

Can't find Python executable "python", you can set the PYTHON env variable.

npm ERR! gyp ERR! node -v v16.13.1
npm ERR! gyp ERR! node-gyp -v v3.8.0
npm ERR! gyp ERR! not ok

3、问题解决方法

首先面向百度编程

经过多次尝试自己成功解决这一问题的方法

3.1 安装编译环境（管理员身份运行）

npm install -g node-gyp 
npm install --global --production windows-build-too

3.2 卸载安装失败的包

npm uninstall node-sass

3.3 重新安装包

npm install sass -i

3.3 重新 npm install

3.4 重新npm run dev

4、成功跑起来
