R 找不到函数"；getSymbols"；使用ShinyApps.io时

我刚刚在Rstudio中完成了交易策略的构建，并计划将其部署到ShinyApps.io上。问题来了

首先，总会有这样一条警告信息：

Warning messages:
1: In getFromNamespace("checkEncoding", "shiny")(file) :
  The file "F:\newFinal/server.R" is not encoded in UTF-8. Please convert its encoding to UTF-8 (e.g. use the menu `File -> Save with Encoding` in RStudio). See http://shiny.rstudio.com/articles/unicode.html for more info. Falling back to the encoding "native.enc".
2: In getFromNamespace("checkEncoding", "shiny")(file) :
  The file "F:\newFinal/server.R" is not encoded in UTF-8. Please convert its encoding to UTF-8 (e.g. use the menu `File -> Save with Encoding` in RStudio). See http://shiny.rstudio.com/articles/unicode.html for more info. Falling back to the encoding "native.enc".

source("helpers.R")
#source("loadfunction.R")
source("main2.R")
#source("main.R")
source("plotperiod.R")

即使我使用UTF-8编码保存了该文件，每次部署应用程序时它仍然会向我显示该警告

另一件事是，我无法在ShinyApps中找到其他文件的来源，如下所示：

Warning messages:
1: In getFromNamespace("checkEncoding", "shiny")(file) :
  The file "F:\newFinal/server.R" is not encoded in UTF-8. Please convert its encoding to UTF-8 (e.g. use the menu `File -> Save with Encoding` in RStudio). See http://shiny.rstudio.com/articles/unicode.html for more info. Falling back to the encoding "native.enc".
2: In getFromNamespace("checkEncoding", "shiny")(file) :
  The file "F:\newFinal/server.R" is not encoded in UTF-8. Please convert its encoding to UTF-8 (e.g. use the menu `File -> Save with Encoding` in RStudio). See http://shiny.rstudio.com/articles/unicode.html for more info. Falling back to the encoding "native.enc".

source("helpers.R")
#source("loadfunction.R")
source("main2.R")
#source("main.R")
source("plotperiod.R")

以下日志显示系统找不到函数“getSymbols”

不确定这是否能解决问题，但为了获取文件源，您需要添加

local

参数并将其设置为

TRUE

，如下所示：

source("helpers.R", local=TRUE)
source("main2.R", local=TRUE)
source("plotperiod.R", local=TRUE)

这对我的事业没有帮助。我仍然得到一个错误。你有相同的问题，作为原来的职位，仍然得到一个错误？如果是，请复制

shinyapps:：showLogs（）

的输出？
