R，install.packages（'devtools'）錯誤

Question

我似乎無法安裝devtools。 我總是收到此消息（最后）：

  * installing *source* package ‘RCurl’ ...
  ** package ‘RCurl’ successfully unpacked and MD5 sums checked
  checking for curl-config... no
  Cannot find curl-config
  ERROR: configuration failed for package ‘RCurl’
  * removing ‘/home/vapri/R/x86_64-pc-linux-gnu-library/3.0/RCurl’
  Warning in install.packages :
    installation of package ‘RCurl’ had non-zero exit status
  ERROR: dependency ‘RCurl’ is not available for package ‘httr’
  * removing ‘/home/vapri/R/x86_64-pc-linux-gnu-library/3.0/httr’
  Warning in install.packages :
    installation of package ‘httr’ had non-zero exit status
  ERROR: dependencies ‘httr’, ‘RCurl’ are not available for package ‘devtools’
  * removing ‘/home/vapri/R/x86_64-pc-linux-gnu-library/3.0/devtools’
  Warning in install.packages :
    installation of package ‘devtools’ had non-zero exit status

The downloaded source packages are in
    ‘/tmp/RtmpqLDAb0/downloaded_packages’

有人可以告訴我怎么了嗎？ 我正在使用Ubuntu 14.04，有些研究似乎暗示可能是這個問題。

Answer 1

仔細觀察：

 checking for curl-config... no
  Cannot find curl-config

您需要curl-config腳本。 通常，您需要一個libcurl*-dev或類似的軟件包，並且發行版之間的名稱可能有所不同。 在我輸入以下內容的系統上：

edd@max:~$ dpkg -S `which curl-config`
libcurl4-nss-dev: /usr/bin/curl-config
edd@max:~$ 

但是還有另外一個libcurl4-gnutls-dev和libcurl4-openssl-dev ，我可以在其他一些系統上使用。

Answer 2

幫助過我。

sudo apt-get install aptitude
sudo apt-get install libcurl4-openssl-dev
sudo apt-get install libxml2-dev
