'。' 不被识别为内部或外部命令，可操作程序或批处理文件

Question

问题来源（我认为）：

 "scripts": {
        "dev-server": "./node_modules/webpack-dev-server/bin/webpack-dev-server.js --config config/webpack.config.js"
      },

错误日志：

> somename@1.0.0 dev-server C:\Users\Admin\Downloads\somename
> ./node_modules/webpack-dev-server/bin/webpack-dev-server.js --config config/we
bpack.config.js

'.' is not recognized as an internal or external command,
operable program or batch file.

我收到此错误，因此，我无法执行以下操作： npm run dev-server 。

有没有办法替换./ part？

只需直接引用二进制文件即可：

    "scripts": {
        "dev-server": "webpack-dev-server --config config/webpack.config.js"
     },

npm将在所有安装的软件包的二进制文件（即node_modules/.bin/ ）在PATH中直接可用的环境中运行脚本，包括webpack-dev-server 。

最好在package.json使用/作为路径分隔符-它可以在Windows以及Linux或OSX上运行。
