在下载了官方提供的工程文件 iview-projcet后，运行npm run dev ,会报错，像上面所示。

后面找到了一个解决方案：

在webpack.*.config文件中，根据你当前的node版本修改为对应的即可。

fs.open(‘./build/env.js‘, ‘w‘, function(err, fd) {
    const buf = ‘export default "development";‘;
    // node 版本问题
    // fs.write(fd, buf, 0, buf.length, 0, function(err, written, buffer) {}); // node --version > v10.1.0
    fs.write(fd, buf, function(err, written, buffer) {}); // node --version < v10.1.0
});
