1. 复现问题

今天准备克隆Redis桌面(GUI)管理客户端，故按照官方文档给出的指令运行时，如下图所示：

但在执行指令npm install --platform=win32却报出如下图错误：

PS D:\Software\RedisDesktopManager\AnotherRedisDesktopManager> npm install --platform=win32 npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead. npm WARN deprecated chokidar@2.1.8: Chokidar 2 does not receive security updates since 2019.

C:\Users\zxy\AppData\Local\npm-cache\_logs\2022-11-04T07_24_57_963Z-debug-0.log

注意看上述错误的倒数第3行，即Cannot read properties of null (reading pickAlgorithm)

2. 分析问题

Cannot read properties of null (reading pickAlgorithm)翻译成中文就是无法读取 null 的属性（读取 pickAlgorithm）

但是，我在运行指令npm install --platform=win32时，并没有涉及pickAlgorithm字段呀，于是，通过查找资料可得如下解决方案:

方案1

重新安装node解决，这并没有解决我的问题，舍弃。

方案2

删了node models重新下。

或者直接下载CNPM（淘宝镜像）进行安装CNPM安装办法：

npm install -g cnpm -registry=https://registry.npm.taobao.org

查看cnpm是否真安装成功:

cnpm -v

这种方式也没有解决我的问题。

于是，使用如下第3种方案解决了我的问题。

3. 解决问题

在终端输入指令npm cache clear --force ，如下所示： PS D:\Software\RedisDesktopManager\AnotherRedisDesktopManager> npm cache clear --force npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead. npm WARN using --force Recommended protections disabled. 再次执行指令npm install --platform=win32 ，即可完成安装，如下所示： PS D:\Software\RedisDesktopManager\AnotherRedisDesktopManager> npm install --platform=win32 npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead. npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See https://v8.dev/blog/math-random for details. npm WARN deprecated browserslist@2.11.3: Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools. npm WARN deprecated debug@4.1.1: Debug versions >=3.2.0 <3.2.7 || >=4 <4.3.1 have a low-severity ReDos regression when used in a Node.js environment.

Upgrade to v2.x.x. added 706 packages, and changed 55 packages in 2m 93 packages are looking for funding run `npm fund` for details 输入npm start启动程序，如下图所示：

此时，报出另外一个错误，即 Cannot find module D:\Software\RedisDesktopManager\AnotherRedisDesktopManager\node_modules\fs.realpath\index.js. Please verify that the package.json has a valid "main" entry 。

即在当前目录下找不到index.js文件，于是，我们去当前目录下区创建该文件即可：

创建index.js文件后，再次执行npm start指令，即可启动程序了，如下所示：
