我正在尝试使用此处显示的cran包中的conda-forge上不存在的r conda软件包：https：//www.anaconda.com/blog/开发人员博客/conda-data-Science/
我以r软件包为例 - 此软件包已经在conda-forge上作为R-Rann存在，但是我用它来测试构建过程是否一般。
。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与我尝试构建的包装无关。我不知道环境变量在哪里(？(" cmd"应该来自。
我采取了以下步骤：
-
conda skeleton cran rann -
conda build r-rann
我还测试了从PIP构建Python软件包，这些工作没有任何问题，因此这似乎不是我的Minconda安装的一般问题。
我的系统：
- ubuntu 17.10
- Miniconda 3，版本4.4.10
这是构建过程的完整日志：

" cmd"是R命令行指令。在Conda-build期间，您下载了RANN的源代码，然后在临时环境中使用R从其构建一个软件包，然后(临时(检查其工作。
该行只是告诉R构建包装rann。当您开发R软件包时，请使用R CMD build <my_package>或R CMD INSTALL --build <my_package>来制作该软件包的可安装存档。
看起来您的Conda-build找不到可以构建软件包的R，尽管通常是在运行Conda-build时设置的临时环境中完成的；并且几乎可以肯定会安装r-base，因此没有真正的理由不找到R。
我已经使用conda-build 3.7.2和conda 4.3.34的Linux(有效ubuntu 16.04(在Windows-Subsystem下运行了代码，并使用R v3.4.1(带有详细的输出(
conda skeleton cran rann
conda build r-rann --R=3.4.1 --debug
它试图在我的系统上运行Rscript CMD INSTALL --build，而不是R CMD build。前者并不是通常在r下构建软件包的方式，在此步骤中，"找不到文件CMD"错误，所以我更详细地研究了它。
首先，我将Meta.yaml与Conda-Forge进行了比较。从跑步要求中不存在libgcc，而conda骨骼设置的YAML中的build quire则不存在R基本 - 我添加了这些并进行了重建(尽管我怀疑这些引起了问题(。这没有解决任何问题，"找不到CMD"错误仍会引发。
我检查了Conda-build的更改程序。RScript用于运行测试，而不是从3.7.2版本开始的R进行测试。我恢复到conda-build = 3.7.1：
conda install conda-build=3.7.1 -vv
conda build r-rann --R=3.4.1 --debug
现在，我经过ccall到r cmd安装 - 构建...，但是在编译过程中仍然出现错误。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是由更改conda-build造成的(使用rscript而不是使用Rscriptr测试包时(导致构建R软件包的问题。您能把这个问题交叉引用到Conda-Build Github。
＆lt; - 编辑 ->
搜索后，我通过a(安装gfortran和b(使用conda-build 3.6.0来创建骨架并构建软件包。conda-build的3.7.0/1扔了一个与版本号相关的错误(没有 - version xxx参数，conda-skelets扔了一个错误re re namespace没有版本；使用 - version xxx参数，conda-skeleton投掷不针对R软件包实现错误的RE版本号(。
上述错误已在conda-build 3.8.0中固定，但我尚未使用
