我正在尝试使用此处显示的appra从CRAN包中构建一个conda-forge上不存在的R conda包：https://www.anaconda.com/blog/developer-blog/conda-data-science/
我使用R包rann作为示例 - 这个包已经在conda-forge上以r-rann的形式存在，但我用它来测试构建过程是否正常工作。
在构建过程中，执行包含行$R CMD INSTALL --build .的脚本“conda_build.sh”。我的问题是构建过程失败，错误Fatal error: cannot open file 'CMD': No such file or directory独立于我尝试构建的包。我不知道环境变量（？）“CMD”应该来自哪里。
我采取了以下步骤：
conda skeleton cran rann conda build r-rann 我还测试过从pip构建Python包，这些工作没有任何问题，所以看起来这不是我的Miniconda安装的一般问题。
我的系统：
以下是构建过程的完整日志：

＆＃34; CMD＆＃34;是一个R命令行指令。在conda-build期间，您下载RANN的源代码，然后在临时环境中使用R构建一个包，然后安装它（暂时）以检查它是否有效。
该行只是告诉R构建包rann。在您开发R软件包时，可以使用R CMD build <my_package>或R CMD INSTALL --build <my_package>来创建该软件包的可安装存档。
看起来你的conda-build无法找到构建软件包的R，尽管这通常是在运行conda-build时设置的临时环境中完成的;并且构建过程几乎肯定会安装r-base所以没有真正的理由不能找到R。
我使用conda-build 3.7.2和conda 4.3.34以及R v3.4.1（详细输出）运行windows-subsystem for linux（有效Ubuntu 16.04）下的代码
conda skeleton cran rann
conda build r-rann --R=3.4.1 --debug
它尝试在我的系统上运行Rscript CMD INSTALL --build，而不是R CMD build。前者并不是如何在R下构建软件包，而在此步骤中，＆＃34;无法找到文件CMD＆＃34;错误被抛出，所以我更详细地研究了它。
首先，我将meta.yaml与conda-forge上的meta.yaml进行了比较。 libgcc缺少运行要求，并且r-base不存在于conda骨架设置的yaml中的构建要求中 - 我添加了这些并重建（尽管我怀疑这些导致问题）。这并没有解决任何问题，＆＃34;无法找到CMD＆＃34;错误仍然存在。
我在conda-build检查了更改日志。 Rscript用于从3.7.2版开始运行测试而不是R。我恢复了conda-build = 3.7.1：
conda install conda-build=3.7.1 -vv
conda build r-rann --R=3.4.1 --debug
现在，我通过ccall到R CMD INSTALL --build ...，但在编译期间仍然出现错误;所以我还没有解决问题。
尽管如此，看起来您最初发布的错误源于对conda-build的更改（使用Rscript而不是 在测试软件包时R导致了构建R软件包的问题。你能不能将这个问题交叉引用到conda-build github上。
＆lt; - 编辑 - ＆gt;
经过一番搜索，我得到了这个工作：a）安装gfortran和b）使用conda-build 3.6.0创建骨架并构建包。 3.7.5 / 1的conda-build抛出了与版本号相关的错误（没有--version XXX参数，conda-skeleton引发了一个错误，名称空间没有版本;使用--version XXX参数，conda-skeleton引发没有为R包实现错误版本号。）
以上错误已在conda-build 3.8.0中修复，但我尚未使用
