 安装

测试

win+R->cmd执行

node -v

配置

在安装目录下创建两个子文件夹node_cache和node_global,我的就是

D:\nodejs\node_cache
D:\nodejs\node_global

在node_global文件下再创建一个子文件夹node_modules

D:\nodejs\node_global\node_modules

配置环境变量

此电脑->右键选择属性

之后一点要点击确定保存

配置npm的路径值

在cmd控制台中配置npm的两个路径值

npm config set prefix "D:\nodejs\node_global"

npm config set cache "D:\nodejs\node_cache"

配置镜像站点 

npm config set registry https://registry.npmmirror.com

这是因为权限不够，导致可以在以管理员身份运行的条件下成功运行，但是在普通用户下不行，需要调整文件夹的权限。

其他几个文件夹也是相同的操作

这个好像是和自己的网络有关。

我就是把之前安装的文件删除，然后重新安装，结果又可以了，这里应该是因为当时第一次安装的时候中途终止了。然后这个说用华为的，但是还是报错了。npm install报错，error ＜https://npm.community＞解决方法_httperror npm install-程序员宅基地https://blog.csdn.net/qq_39564710/article/details/136627630

其实想的大差不差了总结就是：

他整个命令在做的事情，就是先配置npm的路径，对于用npm下载的东西之后是存放在那个文件夹里面，之后在全局运行vue.cmd这个文件.所以导致失败的原因就看你是有以下的几种情况：

1.npm下载路径没有配置

npm config set prefix "D:\nodejs\node_global"

这就导致下载的vue.cmd不在这个文件夹里面

2.用户没有写入文件的权限

可能安装的目录需要有管理员的身份才能写入，这就导致在管理员身份的命令行下面能够安装文件，但是在普通的用户下却不行，所以就需要修改文件的权限，让普通用户也能够访问。

 3.镜像文件的证书过期

这个就是一个网上比较多的情况了，因为证书过期导致下载不了，这个常见的处理就是重新配置最新的镜像站点。

npm最新淘宝镜像站已经更新（2024-2-22）_npm淘宝镜像最新-程序员宅基地

4.环境变量没有配置

这个也是比较常见的情况，大概的意思就是文件你有了，可以在有vue.cmd的目录下面运行vue -v，但是不能在全局使用，这就是环境变量的作用，所以如果没有配置就导致无法全局使用。

5.网络不稳定

 如果下载太久还失败，这多半就是这个原因了，其实我大概已经猜到是这个原因，但是之前没问题就没怎么管这个，结果还真的是这个导致的，我服了。

总结

首先看你下载的目录下面有没有vue的文件，如果没有就说明是下载失败了，优先考虑情况1,2,3,5；如果有就优先考虑是不是环境变量没有配置。这个我觉得应该是全网最全面的分析，如果还有其他情况，大佬们可以在评论区补充。

vue项目创建

 官网先下载安装visual Studio Code。Download Visual Studio Code - Mac, Linux, Windowshttps://code.visualstudio.com/Download

 选择自己准备存放的文件夹->调出终端

执行（一直点击确定）

npm init vue@latest

然后按照他的提示执行下面三条命令，

  cd vue-project
  npm install
  npm run dev

 但是结果出现这个，不用想应该又是网络的问题。
