我使用Rstudio版本0.99.902和R版本3.3.1（2016-06-21）。
我已经写了一个我想提交给CRAN的包。 当我运行devtools::check()函数（包括–as-cran）时，我成功通过了所有testing ， 没有错误/警告/注释。
虽然当我运行在我的terminal（Ubuntu 15.10）相同，它给了我错误和警告。
运行R CMD build –
R CMD build mypackage //home/akilesh/anaconda2/bin/R: 12: [: Linux: unexpected operator /home/akilesh/anaconda2/lib/R/bin/R: 12: [: Linux: unexpected operator * checking for file 'mypackage/DESCRIPTION' ...

运行R CMD check –

这是我的DESCRIPTION文件

我无法理解为什么会发生这种情况。 我仍然可以将我的软件包提交给CRAN，因为它在Rstudio上运行时通过testing， devtools::check() ？ 虽然它在Rstudio上运行时通过了所有的testing，但为什么它不通过terminal的testing呢？ 它与安装Conda有什么关系？
/home/akilesh/anaconda2/lib/R/bin/R: 12: [: Linux: unexpected operator的意义是什么/home/akilesh/anaconda2/lib/R/bin/R: 12: [: Linux: unexpected operator错误？
UPDATE ：添加了R的最低版本号，以及所有的import。 徒然。
