我正在开发一个包，我正在使用devtools来检查包的功能。我从devtools的两个函数中得到了一些矛盾的结果。当我使用<ion-header no-border>
<ion-navbar color="white">
<button ion-button menuToggle> <!--menuToggle removed and ion button hidden. You don't wanna show menu when they are yet to sign in-->
<ion-icon name="menu"></ion-icon>
</button>
<ion-title>Login</ion-title>
</ion-navbar>
函数检查示例是否正常工作时，它完成没有任何错误。但是，当我使用devtools::run_example时，它在检查示例步骤中失败，即
devtools::check所以我不确定为什么我从这两个函数得到矛盾的结果。特别是* using R version 3.4.1 (2017-06-30)

函数抱怨它无法从我在DESCRIPTION文件中导入的库中找到某个函数。
