bisheng.config.js

module.exports = {
  source: './posts',
  output: './_site',
  theme: 'bisheng-theme-one',
  port: 8002,
};

package.json包版本如下：

"bisheng": "^3.1.0-beta.4",
"bisheng-theme-one": "^0.2.37",

运行bisheng start就会报变异错误，如下：

我把webpack的mode设置成'development', 能看到是这行代码报错

const themeConfig = JSON.parse('{{ themeConfig | safe }}');

最后在config.js配置个themeConfig空对象就好了
