     阅读:29

前言:

        运行小程序代码时出现这个报错,百度了好久终于解决,整理一下以作纪念。

报错:

原因:

        有说是被墙了,让换淘宝镜像的,未能解决。

        有说是要安装python环境,推荐安装2.7,设置了环境变量之后,报错依旧。

        ......

        我这边的问题其实是node.js的版本问题。

解决方案1:

          win + r 输入命令 cmd 运行 node -v 查看版本,

        卸载后,安装14.18.3,旧版本下载地址:node.js 14.18.3 版本下载

 解决方案2:

        利用nvm版本控制,nvm for windows 下载,下载地址:nvm下载,github

        推荐下载 nvm-setup.zip, 解压后直接安装使用(推荐安装到默认路径)。

        输入命令 nvm

        出现图示则安装成功(我这边重启电脑后才出现这个的😓)

        附nvm部分命令:

  • nvm install v14.18.3  安装指定版本(以14.18.3为例)
  • nvm list 查看已有版本
  • nvm use v14.18.3 切换到指定版本(以14.18.3为例)
  • nvm uninstall 14.18.3 卸载指定版本(以14.18.3为例)

新的问题(使用方案2出现):

        利用nvm切换版本之后,npm无法使用,提示:‘npm’ 不是内部或外部命令,也不是可运行的程

原因:

        nvm对应的版本文件夹内,文件夹node_modules为空

解决:

        在 node.js 14.18.3 版本下载 下载14.18.3的.zip二进制文件夹,然后解压,将node_modules问价夹替换掉,并将如下4个文件粘贴进去。

 完结撒盐!
