配置失败，因为没有找到libcurl

I am trying to pull some json data from a remote server using fromJSON:

我正在尝试使用fromJSON从远程服务器提取一些json数据:

> server <- 'http://111.111.000.00:3000'> streams <- fromJSON(paste(server, '/output/streams', sep=""), flatten=TRUE)

Result:

结果:

Error: Required package curl not found. Please run: install.packages('curl')

So I tried to install it:

所以我试着安装它:

Then I tried to install libcurl4-openssl-dev:

然后我尝试安装libcurl4-openssl-dev:

> install.packages("libcurl4-openssl-dev")Installing package into ‘/home/lau/R/x86_64-pc-linux-gnu-library/3.3’(as ‘lib’ is unspecified)Warning in install.packages :  package ‘libcurl4-openssl-dev’ is not available (for R version 3.3.1)

Why? What is going wrong? How can I fix it?

为什么?什么错了吗?我怎样才能修好它呢?

It was ok when I was on Xubuntu 16.04. But now I am on Kubuntu 16.10.

当我使用Xubuntu 16.04时，一切正常。但现在我是Kubuntu的16.10。

Any ideas?

什么好主意吗?

2 个解决方案

#1

libcurl4-openssl-dev is not a R package, but rather a linux library.

libcurl4-openssl-dev不是一个R包，而是一个linux库。

In a console type:

在控制台类型:

sudo apt-get install libcurl4-openssl-dev

Note: you need sudo powers.

注意:你需要超能力。

#2

The Linux release is: CentOS Linux release 7.3.1611 (Core)

Linux发行版是:CentOS Linux发行版7.3.1611(核心)

In my case, I was trying to install R package: devtools

在我的例子中，我尝试安装R包:devtools。

------------------------- ANTICONF ERROR ---------------------------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 yourPATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-configis unavailable you can set INCLUDE_DIR and LIB_DIR manually via:R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

I checked $PATH, 'pkg-config' was in the PATH. But there is no libcurl.pc file in PKG_CONFIG_PATH (/usr/local/lib/pkgconfig/).

我检查了$PATH，“pkg-config”在路径中。但是没有libcurl。PKG_CONFIG_PATH中的pc文件(/usr/local/lib/pkgconfig/)。

Here is how I solved the problem.

我是这样解决这个问题的。

suwget https://github.com/curl/curl/releases/download/curl-7_55_0/curl-7.55.0.tar.gz./configuremake make install

After this, I saw libcurl.pc file in PKG_CONFIG_PATH (/usr/local/lib/pkgconfig/).

之后，我看到了libcurl。PKG_CONFIG_PATH中的pc文件(/usr/local/lib/pkgconfig/)。
