尝试安装 RPostgreSQL 时，为什么我得到包“DBI”没有名称空间？

Question

我正在尝试以下命令：

r CMD INSTALL RPostgreSQL_0.1-7.tar.gz

我收到以下错误消息：

* installing to library 'C:/.../R/win-library/2.13'
* installing *source* package 'RPostgreSQL' ...
** libs

我安装了 DBI 使用

R CMD install DBI_0.1-10.tar.gz

它似乎工作正常。

我也试过了

install.packages('RPostgreSQL_0.1-7')

但得到

警告信息： 在 getDependencies(pkgs, dependencies, available, lib) 中： 包“RPostgreSQL_0.1-7”不可用（适用于 R 版本 2.13.1）

Answer 1

您的 R 安装是否有问题或异常？

此外，R 开发版本正在为每个包都需要一个 NAMESPACE，如果需要，为一个包构建一个不提供它。但这应该只影响 R-devel 而不是当前版本。你运行的是哪个版本？

无论如何，为了记录，它在这里仍然可以正常安装（R 2.13.1，Ubuntu 11.0，在 ~/.R/Makevars 中进行了一些自定义）
