reactjs - React 中的 Font Awesome 图标

Question

使用字符串作为图标参数的值时，我无法使 Font Awesome 图标正常工作。
这个工作:

import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';
import { faCoffee } from '@fortawesome/free-solid-svg-icons'

 <FontAwesomeIcon icon={faCoffee} />

然而，这不会:

import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';

<FontAwesomeIcon icon="coffee" />

根据这个 documentation这应该。
但我是 React 的新手，所以可能会遗漏一些东西。
使用javascript。使用 react cli 创建的项目。
包.json:

    ]
  },
  "browserslist": {

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

“不工作”我的意思是图标在页面上不可见并且控制台有错误:“找不到图标{前缀:“fas”，图标名称:“咖啡”}”

Answer 1

您需要导入 library像这样:import { library } from '@fortawesome/fontawesome-svg-core'然后添加您要使用的图标。

import { faCoffee } from '@fortawesome/free-solid-svg-icons'

library.add(faCoffee /*, faCheckSquare, etc*/)

在此之后，您应该能够将图标用作“咖啡”。如果您没有将图标添加到库中，它们将不会包含在包中，因此会出现错误。
