为 4.0.2 安装吸墨纸时遇到困难。
我运行以下代码:
require(devtools)
install_github("braverock/blotter")
install_github("braverock/quantstrat")
我收到以下错误消息:
Failed to install 'blotter' from GitHub:
(converted from warning) installation of package ‘/var/folders/7f/fzwn25053j3bp0yd_7swzf540000gn/T//Rtmp5kiwSh/file14db938bb63bf/blotter_0.15.0.tar.gz’ had non-zero exit status
我已经成功安装了 xts、PerformanceAnalytics 和 FinancialInstrument。我还安装了开发工具 Clang 8.0(尽管我相信在 R 4.0 及更高版本中不再需要它)。
任何帮助表示赞赏。提前致谢。
