未找到包創建conda環境，但無法安裝它

Question

如何解決此問題？

balter@exalab3:~$ conda create -n r322 r=3.2.2 
Fetching package metadata ......... 
Solving package specifications: . 


PackageNotFoundError: Package not found: '' Dependency missing in current linux-64 channels: 
    - r 3.2.2* -> r-base 3.2.2 -> libgcc 

Close matches found; did you mean one of these? 

    libgcc: libgd, libmagic 

You can search for packages on anaconda.org with 

    anaconda search -t conda libgcc 

balter@exalab3:~$ conda list | grep libgcc 
balter@exalab3:~$ conda install libgcc

充分披露，這並不直接解決您上市（冒着downvote）的問題，但我認爲這個替代方法適用於什麼，我相信你想做的事情。

棘手的是，r語言是在不同的channel。特別是，this看起來像你想要的包。理想情況下，conda create命令可以讓您指定該頻道，但看起來不像那樣。相反，您可以嘗試創建一個空的環境 - this看起來像推薦的方式 - 然後在該環境中進行安裝。換句話說，你可以試試這個：

conda create -n r322 python 
source activate r322 
conda install --channel r r=3.3.2
