antd-mobile-rn 自定义主题不生效

[lsfern]

• "antd-mobile-rn": "^2.2.0",
• "react-native": "^0.55.4",
• 操作系统及其版本：win7

custon-rn-theme.js:
const path = require('path');
const fs = require('fs');
// for 1.x
// const defaultVars = require('antd-mobile/lib/style/themes/default');
// for 2.x
const defaultVars = require('antd-mobile-rn/lib/style/themes/default.native');
const customVars = require('../theme');
// for 1.x
// const themePath = path.resolve(require.resolve('antd-mobile'), '../style/themes/default.js');
// for 2.x
const themePath = path.resolve(require.resolve('antd-mobile-rn'), '../style/themes/default.native.js');
const themeVars = Object.assign({}, defaultVars, customVars);

if (fs.statSync(themePath).isFile()) {
fs.writeFileSync(
themePath,
'var brandPrimary = "#F00"; var brandPrimaryTap = "#1284d6";module.exports = ' + JSON.stringify(themeVars)
);
}

theme.js 变量名和default的名字相同
