在R上安装curl和readr

Question

亲爱的社区.我尝试安装readr,但它给了我一个错误,因为没有卷曲.然后我尝试安装curl,它要求另一个依赖项.我在命令提示符中验证它,但它看起来已经安装.任何的想法 ？见打击:非常感谢

尝试安装readr:

尝试安装curl

在终端安装curl:

[oracle@localhost data]$ sudo yum -y install curl
Loaded plugins: langpacks
Package curl-7.29.0-19.el7.x86_64 already installed and latest version
Nothing to do
[oracle@localhost data]$ sudo yum -y install libcurl
Loaded plugins: langpacks
Package libcurl-7.29.0-19.el7.x86_64 already installed and latest version
Nothing to do

它看起来像libcurl？

[oracle@localhost data]$ locate libcurl 
/home/oracle/anaconda/lib/libcurl.a
/home/oracle/anaconda/lib/libcurl.la
/home/oracle/anaconda/lib/libcurl.so
/home/oracle/anaconda/lib/libcurl.so.4
/home/oracle/anaconda/lib/libcurl.so.4.3.0
/home/oracle/anaconda/lib/pkgconfig/libcurl.pc
/home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.a
/home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.la
/home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.so
/home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.so.4
/home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.so.4.3.0
/home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/pkgconfig/libcurl.pc
/usr/lib64/libcurl.so.4
/usr/lib64/libcurl.so.4.3.0

那么curl-config就在那里..

[oracle@localhost data]$ locate curl-config
/home/oracle/anaconda/bin/curl-config
/home/oracle/anaconda/pkgs/curl-7.38.0-0/bin/curl-config
[oracle@localhost data]$ 

Answer 1

我使用这个命令在Ubuntu 14.04上解决了这个问题

sudo apt-get install libcurl4-openssl-dev

未来的用户可以使用以下方法搜索最新的libcurl:
apt-cache search libcurl

Answer 2

实际问题是:

找不到文件curl.h.

R建议一个解决方案:

确保已安装curl开发库,例如libcurl4-openssl-dev(deb)或libcurl-devel(rpm)

所以,试试:

sudo yum -y install libcurl-devel
