gyp verb check python checking for Python executable “python2“ in the PATH

背景

适用npm i安装环境时出现错误
根据错误信息，应该是node版本问题导致的，但单独安装[email protected]时也出现同样错误。

错误分析

有些blog说到这种错误要安装python，或者把给node设置python的引用，也许有用，但我认为前端不是这么不方便的东西，正常都是适用包管理器就能配置好环境，基本上环境配置90%的错误都是node版本的问题。
从错误信息来看，是在使用 node 16.20 后出现的错误，基本可以考虑node版本问题

解决方案

更换node版本即可，一般旧项目使用旧node，新项目使用新node。
当前时间2023-06-03，node 版本最新稳定版是18.16。
node.js
我们常用的版本是16、10。一般切换都是在这两者切换。

使用nvm切换node版本

nvm Win下载地址

一路next安装即可。

安装完成后，使用命令安装node16 或者 node10.

nvm install 16
...
nvm use 16

nvm install 10
...
nvm use 10

正常的样子

C:\Users\admin>nvm install 10
Downloading node.js version 10.24.1 (64-bit)...
Complete
Creating C:\Users\admin\AppData\Roaming\nvm\temp

Downloading npm version 6.14.12... Complete
Installing npm v6.14.12...

Installation complete. If you want to use this version, type

nvm use 10.24.1

C:\Users\admin>nvm use 10
Now using node v10.24.1 (64-bit)
