我正在尝试从vuejs'github repository运行vue-hackernews-2.0示例
在设置部分,它解释了如何安装项目:
# install dependencies
npm install # or yarn
# serve in dev mode, with hot reload at localhost:8080
npm run dev
# build for production
npm run build
# serve in production mode
npm start
我做了npm安装。在server.js中将端口更改为8888后,我在命令行上键入了“npm run dev”。
> vue-hackernews-2.0@ dev D:\Users\212399486\WebstormProjects\vue-hackernews-2.0-master
> node server
server started at localhost:8888
DONE Compiled successfully in 16328ms 1:02:18 PM
DONE Compiled successfully in 17845ms 1:02:19 PM
webpack built bd162a76119031a85eed in 17845ms
当我去localhost时:8888它只会尝试加载1分钟然后失败,控制台上没有任何东西。
我想我也应该尝试“npm run build”和“npm start”,所以我也使用了两个命令。 “npm run build”成功创建了dist文件。
但是在“npm start”之后我收到了这个错误:

需要Node.js 7 +
我设法让它没有任何问题。
$node -v
v8.3.0
$npm -v
5.3.0
要更改默认端口,您必须编辑package.json
脚本:
dev:cross-env PORT=8888 node server
开始:cross-env PORT=8888 NODE_ENV=production node server
然后运行npm run dev
> vue-hackernews-2.0@ dev /home/emx/so/vue-hackernews-2.0
> cross-env PORT=8888 node server
server started at localhost:8888

您使用的是不受支持的节点版本。您的错误指向node v6.11.2
,请参阅下文。
npm ERR! Windows_NT 6.1.7601
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "D:\\Users\\212399486\\AppData\\Roaming\\npm\\node_modules\\npm\\bin\\npm-cli.js" "start"
npm ERR! node v6.11.2
npm ERR! npm v3.10.8
vue-hackernews-2.0需要Node.js 7+
。将您的节点升级到7+版本,你应该没问题。我还建议您更新您的npm版本。
如果您需要说明,请参阅the answers to this question以获取有关如何更新节点版本的详细信息。
