麻煩下載{} data.table包

Question

我最初使用下載的data.table包從CRAN：

install.packages() 

它下載版本1.9.4，打了幾個減速帶，並打算通過這個網站，我想通後我不得不從github下載最新版本。爲了做到這一點，我試圖下載到「devtools」，但我沒有成功。以下是我得到的錯誤：

* installing *source* package ‘curl’ ...

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

* 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，我想另一種方法，並從https://cran.r-project.org/web/packages/data.table/index.html下載.tar.gz文件。

然後使用：

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

下載成功，但我得到了下面的錯誤嘗試加載它的時候：

> 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

Attaching package: ‘data.table’ 

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

    last

    lazy-load database '/home/trader/R/x86_64-pc-linux-gnu-library/3.2/data.table/help/data.table.rdb' is corrupt 
In addition: Warning message:

我不知道我現在應該做什麼。有人可以幫忙嗎？

Answer 1

看起來像損壞的安裝。

1. 關閉所有會話
2. 開始在控制檯單一的清潔R對話（排除任何IDE問題）
3. 安裝從GitHub資源庫的開發版本直接使用：

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

1. 安裝後您可以可選通過

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

如果你想安裝最新版本CRAN只是跳過repos參數install.packages驗證所有測試。
