我有虚拟 Debian 服务器。即
braingen@vm-mob:~$ Linux vm-mob 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2+deb10u1 (2020-06-07) x86_64
我已经安装了 r-base-core
sudo apt-get install r-base-core
R
当在 R 控制台中时，我尝试安装 keras
install.packages("keras")
当我这样做时，我遇到了麻烦
he downloaded source packages are in
‘/tmp/RtmpxmyvE9/downloaded_packages’
Warning messages:
1: In install.packages("keras") :

所以我当然无法加载库。
如何正确安装 keras 和依赖项？ 谢谢

最佳答案
由于缺少系统 header ，“png”包似乎无法安装。我在 Docker 容器中尝试过，但无法在本地重现您的错误。两个想法: a) 也许需要一些额外的系统依赖项，但您正在使用的 debian 镜像中未包含这些依赖项？也许像 apt install png-dev 这样的东西可以让它工作。
b) 也许更新 R 版本？ R 3.5 已发布 3 年多了，这可能是问题的根本原因，R 当前的发布版本是 4.1.1。
