Question

我正在尝试通过ta-indicator安装gem install ta-indicator gem，但安装失败并出现以下错误。我错过了什么？

talib.c:2:32: fatal error: ta-lib/ta_abstract.h: No such file or directory

感谢SO的其他帮助，我发现我的路径上需要ta-lb JAR（如下所示）。 JAR位于~/Desktop/_REPOS/misc/stock_analysis/forex/oanda/ruby：

getTimes.rb  indicators_test.rb  oanda_api.rb  ruby.algorithms.rb  ta-lib-0.4.0.jar

独特的问题因为：

我正在使用windows 10和git-bash.exe来运行命令（不是linux）

将完全指定的路径添加到ruby gem install似乎不可能（可能因为我不知道我在做什么）

Answer 1

这是一个很酷的技术分析库。无论如何，似乎你缺少C库开发头文件。你可以从TA-Lib site下载。头文件（.h）应该放在/usr/include/ta-lib目录中。

这可能是gem install cannot find a header file

的副本

gem安装包括引用的JAR失败
