在 R 中安装 quantmod

Question

我尝试安装 R quantmod

当我尝试时：

install.packages('quantmod')

我明白了：

Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
also installing the dependency ‘curl’

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=...'

The downloaded source packages are in
‘/tmp/RtmpeR1Cmy/downloaded_packages’  Using PKG_LIBS=-lcurl

而且我不能运行这个库。

当我尝试时：

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

我明白了：

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？

P.S。我的 R 版本 3.4.4 (2018-03-15) -- "Someone to Lean On"

看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包：

install.packages('quantmod')

如果这不起作用，请编辑您的问题和post任何其他错误消息。
