npm 安装软件报报错Getting "Cannot read property 'pickAlgorithm' of null" error in react native

I get an error when running npm install. The error is:

npm ERR! Cannot read property 'pickAlgorithm' of null

npm ERR! A complete log of this run can be found in:
npm ERR!    npm-cache\_logs\2021-10-14T08_03_47_266Z-debug.log

I did the following but the error stays:

1. Deleted node-modules
2. Deleted the given file
3. Running npm cache clear --force

Environment:

OS: Windows 10
react native: 0.65.1
Node: 14.17.4
npm: 7.21.0

解决方案如下：

在ionic 项目执行 npm i 命令时，出现Error: not found: python2的错误，错误如下图

解决方案

1、下载python https://www.python.org/download/releases/2.7/

2、安装python

3、设置python环境变量

1）电脑右击——属性——高级系统设置—高级—环境变量

2）系统变量—Path 中添加环境变量 C:\Python27（python安装目录）

4、然后执行 npm rebuild node-sass重构一下

5、然后再执行 npm i 就可以了
