下载 {data.table} 包时遇到问题

Question

我最初使用以下方式从 CRAN 下载 data.table 软件包：

install.packages()

它下载了 1.9.4 版，在遇到一些减速并浏览这个网站后，我想我必须从 github 下载最新版本。为此，我尝试下载到 "devtools"，但没有成功。以下是我得到的错误：

* installing *source* package ‘curl’ ...
** package ‘curl’ successfully unpacked and MD5 sums checked
Package libcurl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcurl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libcurl' found
Package libcurl was not found in the pkg-config search path.

Configuration failed because libcurl was not found. Try installing:
 * deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
 * rpm: libcurl-devel (Fedora, CentOS, RHEL)
 * csw: libcurl_dev (Solaris)
If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

The downloaded source packages are in
    ‘/tmp/RtmpMtxhRg/downloaded_packages’

所以我尝试了另一种方法并从 https://cran.r-project.org/web/packages/data.table/index.html 下载了 .tar.gz 文件。

然后使用：

> install.packages("~/Downloads/data.table_1.9.6.tar.gz", repos = NULL, type = "source")

下载成功，但在尝试加载时出现以下错误：

> library("data.table", lib.loc="~/R/x86_64-pc-linux-gnu-library/3.2")
data.table 1.9.6  For help type ?data.table or https://github.com/Rdatatable/data.table/wiki

The following object is masked from ‘package:xts’:

我不确定我现在应该做什么。有人可以帮忙吗？

看起来安装已损坏。

关闭所有会话
在控制台中启动单个清理 R 会话（以排除任何 IDE 问题）
直接使用 github 存储库安装开发版本：

install.packages("data.table", repos = "https://Rdatatable.github.io/data.table")

安装后您可以选择通过

library(data.table)
test.data.table()

如果您想安装最新的 CRAN 版本，只需跳过 repos 到 install.packages 的参数。
