Question

只需按照教程，这就是版本信息。

[root@localhost my-project]# node -v
v6.11.3

[root@localhost my-project]# npm -v
3.10.10

[root@localhost my-project]# vue --version
2.9.2

[root@localhost my-project]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)

只需使用easy命令运行，8080端口上没有任何程序运行。

npm install --global vue-cli
vue init webpack my-project
cd my-project
npm install
npm run dev

然后npm安装输出错误，是否意味着它没有完成安装？

继续安装，我不知道某些package.json有什么问题，我从不更改安装进度中的任何代码。只需删除目录node_modules并再次运行npm install即可。在日志文件中出现此错误。

Answer 1

看起来你的一个package.json文件已损坏：

private void Button_Click_1(object sender, RoutedEventArgs e){
 string nFilter = "CSV File|*.csv";
 string nTitle = "Save CSV File";
 string newCSVName = newCSVName;

 SaveFileD(nFilter, nTitle, newCSVName);}

当NPM从存储库中获取Mocha-Nightwatch时，丢失的文本Diogo Monteiro <diogo.gmtps://github.com/diogogmt)已丢失。

我会删除文件ail.com> (ht并再次运行node_modules/.staging/mocha-nightwatch-2017d835/package.json。
