Question

这里是错误截图的链接:https://drive.google.com/open?id=1HL-Fy1M4tHp9qMUpt88PzOfI10AHHem- .

这是使用颜色的代码部分。

const theme = createMuiTheme({
  palette: {
    primary: {
      light: '#33c9dc',
      main: '#00bcd4',
      dark: '#008394',
      contrastText: '#fff'
    },
    secondary: {
      light: '#ff6333',
      main: '#ff3d00',
      dark: '#b22a00',
      contrastText: '#fff'
    }
  },
  typography: {
    useNextVariants: true
  },
  form: {
    textAlign: "center"
  },
  image: {
    margin: "10px auto 10px auto"
  },
  pageTitle: {
    margin: "10px auto 10px auto"
  },
  textField: {
    margin: "10px auto 10px auto"
  },
  button: {
    marginTop: 20,
    position: "relative"
  },
  customError: {
    color: "red",
    fontSize: "0.8rem",
    marginTop: 5
  },
  progress: {
    position: "absolute"
  }
});

我已经尝试将颜色从十六进制值更改为 rgb 值，但没有用。

我对这个问题的解决方案是将所有样式对象放在另一个对象中，而忽略(调色板)对象，并只展开不包含(调色板)的对象

const theme = createMuiTheme({
  palette: {
      primary: {
        light: '#33c9dc',
        main: '#00bcd4',
        dark: '#008394',
        contrastText: '#fff'
      },
      secondary: {
        light: '#ff6333',
        main: '#ff3d00',
        dark: '#b22a00',
        contrastText: '#fff'
      }
    },

    // the object to be spread
    spreadThis: {
       typography: {
        useNextVariants: true
      },
      form: {
        textAlign: "center"
      },
      image: {
        margin: "10px auto 10px auto"
      },
      pageTitle: {
        margin: "10px auto 10px auto"
      },
      textField: {
        margin: "10px auto 10px auto"
      },
      button: {
        marginTop: 20,
        position: "relative"
      },
      customError: {
        color: "red",
        fontSize: "0.8rem",
        marginTop: 5
      },
      progress: {
        position: "absolute"
      }
    }
});

现在您可以在样式对象中执行此操作

const style = theme => ({
  ...theme.spreadThis
});    

希望这对你也有用!祝你好运
