[英]Failed to install devtools in R 3.1.2
I was trying to install the devtools package in Rstudio by install.packages("devtools")
but failed. 我试图通过
install.packages("devtools")
在Rstudio中安装devtools包,但失败了。 The error messages are: 错误消息是:

Perhaps you should add the directory containing `libxml-2.0.pc'
to the PKG_CONFIG_PATH environment variable

Looks like it has trouble finding libxml-2.0
. 看起来很难找到
libxml-2.0
。 Does anyone know an easy fix to this? 有谁知道这个很容易解决? I'm using R version 3.1.2.
我正在使用R版本3.1.2。
Eventually I fixed the problem by: 最终我通过以下方式修复了问题:
sudo apt-get install libxml2-dev
Then another problems popped up: 然后出现了另一个问题:
Error : object ‘curl_fetch_memory’ is not exported by 'namespace:curl'
which can be solved by installing the curl package: 这可以通过安装curl包来解决:
install.packages("curl")
您只需要更新到最新版本的R(R版本3.2.1)
It require some developer libraries (sources): curl developer
, xml2 developer
as dependecy. 它需要一些开发人员库(源代码):
curl developer
, xml2 developer
作为依赖。 so install it with the package repository (yum, dnf, apt-get) and retry to install the devtools package in R. 所以用包存储库(yum,dnf,apt-get)安装它,然后重试在R中安装devtools包。
