在R中安装quantmod

Question

我试着安装R quantmod

当我尝试：

install.packages('quantmod')

我看到：

Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)

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=...'

当我尝试：

install.packages("quantmod", repos="https://github.com/joshuaulrich/quantmod")

我看到：

Warning in install.packages :
package ‘quantmod’ is not available (for R version 3.4.4)

但是R版本3.4.4是最新的！！

有什么问题吗？

P.S.我的R版本3.4.4 (2018-03-15) --“有人精益”

看起来您需要为您的系统安装curl。打开终端并运行：

sudo apt-get update
sudo apt-get install curl libcurl4-openssl-dev libssl-dev

然后在R中再次尝试安装您的软件包：

install.packages('quantmod')

如果这不起作用，编辑你的问题，并发布任何额外的错误信息。
