有出现的问题是，没有Rblas。我有：
It appears that the problem is that there is no Rblas. I have:
- 在尝试安装满贯，TM和MAXENT单独
- 在安装确认GCC
- 在安装了其它的R程序包（Zelig，GGPLOT2），没有问题
- 阅读这些 <一个href="http://stackoverflow.com/questions/16710047/usr-bin-ld-cannot-find-lnameofthelibrary?lq=1">SO 问题。
- 在试图了解在此输入链接的描述上的BLAS R文件
- Tried installing slam, tm, and maxent separately
- Confirmed gcc is installed
- Installed other R packages (Zelig, ggplot2) with no problem
- Read these SO questions.
- Tried to understand enter link description herethe R documentation on BLAS
我认为这个问题为R寻找一个不同版本的BLAS比GCC使用。但我真的不知道。我将preFER不重新安装的R，因为它是根据在服务器上大量使用。
I think the problem is R looking for a different version of BLAS than gcc uses. But I really have no idea. I would prefer not to have to reinstall R, as it is under heavy use on the server.
我该怎么办？
推荐答案
想通了。亚马逊的默认机映像使用阿特拉斯BLAS。当所有的默认安装ř指向，但RTextTools预计普通BLAS。我卸载阿特拉斯，卸载R，重新安装R，和当时能够安装RTextTools。
Figured it out. Amazon's default machine image uses the Atlas BLAS. R points to that when installed with all defaults, but RTextTools expects the ordinary BLAS. I uninstalled Atlas, uninstalled R, reinstalled R, and was then able to install RTextTools.
这篇关于R程序包，海湾合作委员会，并BLAS在Amazon EC2的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
