after 2day's digging.i just changed my package.json from this:

 "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },

to this:

"browserslist": {
    "production": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
