Highcharter离线导出

Question

离线高级包导出不起作用

此可重现的示例（不适用于我），强制包含exportChartLocal

export <- list( list(text = "PNG", 
                     onclick = JS("function () {this.exportChartLocal(); }")), 
                list(text = "JPEG", 
                     onclick = JS("function () {this.exportChartLocal({ type: 'image/jpeg' }); }")
                     )
               )

highchart() %>% 
hc_chart(type = "line" ) %>% 
hc_xAxis(cars$speed) %>% 
hc_add_series(cars$dist) %>% 
hc_exporting(enabled = TRUE, 
             allowHTML = F, 
             fallbackToExportServer = F, 
             formAttributes = list(target = "_blank"), 
              buttons = list(contextButton = list(menuItems = export))
             )

还是我做错了什么？ （我在github https://github.com/jbkunst/highcharter/issues/126上发现了一个有关此问题的开放错误）

我也发现了类似的问题（Highchart export offline），但这对我不起作用
