我安装了webpack ^ 3.0.0和webpack-dev-server ^ 2.9.1（在项目和全局范围内）。
在项目根目录中运行{
"_id" : ObjectId("59d128805b19310ac8ab3fc2"),
"categories" : [
{
"k" : "Location"
},
{
"k" : "DeviceType"
},
{
"k" : "Style"
},
{
"k" : "Color"
}
]
}
后，出现错误
webpack-dev-serverprojet根目录下的webpack.config.js文件包含以下内容：
Invalid configuration object. webpack-dev-server has been initialised
using a configuration object that does not match the API schema.
- configuration has an unknown property 'error'. These properties are
valid:
object { hot?, hotOnly?, lazy?, bonjour?, host?, allowedHosts?,
filename?, publicPath?, port?, socket?, watchOptions?, headers?,
clientLogLevel?, overlay?, progress?, key?, cert?, ca?, pfx?,
pfxPassphrase?, requestCert?, inline?, disableHostCheck?, public?,
https?, contentBase?, watchContentBase?, open?, useLocalIp?, openPage?,
features?, compress?, proxy?, historyApiFallback?, staticOptions?,
setup?, before?, after?, stats?, reporter?, noInfo?, quiet?,
serverSideRender?, index?, log?, warn? }
我已尝试按照this SO question中的建议，但无济于事。如何启动webpack？
我还注意到，当我在全局安装webpack-dev-server ^ 2.9.1时，它拒绝承认webpack ^ 3.0.0的同行，尽管它存在。这有关系吗？

问题与问题末尾提到的全球安装有关。从项目根目录运行webpack-dev-server似乎导致项目安装和全局安装开始运行，因此它们存在相互的端口冲突。其中一个人在检测到这个冲突时抛出了一个错误，另一个人发现这个错误，认为这是额外的配置输入。
使用webpack-dev-server的项目安装解决了这个问题。

解决了webpack-sev-server版本2.9.3（全局/本地实例冲突）。
