加载 gdata 包时如何修复 Perl 警告消息?
How to fix Perl warning message when loading gdata package?
我更新了 Strawberry Perl 64-bit 5.30.2001
和 gdata
包。现在,在加载 library(gdata)
时,我总是收到似乎与 Perl 相关的警告消息。
suppressPackageStartupMessages(library(gdata))
# Warning messages:
# 1: In system(cmd, intern = intern, wait = wait | intern, show.output.on.console = wait, :
# running command 'C:\Windows\system32\cmd.exe /c ftype perl' had status 2
# 2: In system(cmd, intern = intern, wait = wait | intern, show.output.on.console = wait, :
# running command 'C:\Windows\system32\cmd.exe /c ftype perl' had status 2
不过read.xls
,我需要的功能,好像运行不错,就是每次用的时候都会重复警告
read.xls("http://file-examples-com.github.io/uploads/2017/02/file_example_XLS_10.xls")

# 2: In system(cmd, intern = intern, wait = wait | intern, show.output.on.console = wait, :
# running command 'C:\Windows\system32\cmd.exe /c ftype perl' had status 2
我不确定如何处理这个警告,因为它对我没有任何意义,我可能只是忽略它并用 suppressWarnings()
包围它。
不过,有人知道解决这个问题的方法吗?我无法通过谷歌搜索找到任何东西,也不知道从哪里开始,也不知道到底出了什么问题。

我在新安装的 R、gdata
和 Strawberry Perl 版本中遇到了同样的问题。我终于找到 this answer 一个不同的(但相关的)问题。根据那里的建议,我 运行 在 elevated 命令提示符上执行以下操作:
FTYPE perl=C:\Strawberry\perl\bin\perl.exe %1 %*
这为我解决了问题 – 但是:我不确定像这样设置 FTYPE
是否会产生任何不良副作用。所以要小心。
更新:上面的命令 确实 为我抑制了警告“ftype perl' had status 2”,但是 gdata
仍然有问题:
gdata: Unable to load perl libaries needed by read.xls()
gdata: to support 'XLSX' (Excel 2007+) files.
gdata: Run the function 'installXLSXsupport()'
gdata: to automatically download and install the perl
gdata: libaries needed to support Excel XLS and XLSX formats.
但是,installXLSXsupport()
失败并出现了不明确的错误消息。
然后我运行
Sys.which("perl")
perl
"C:\rtools40\usr\bin\perl.exe"
并意识到来自 RTools 的 Perl 版本优先于我安装的 Strawberry Perl – 显然 gdata
不“喜欢”那个 Perl 版本。
因此,我决定通过更改 .Renviron
文件 (usethis::edit_r_environ()
):
让 Strawberry Perl 优先于 RTools
PATH="${RTOOLS40_HOME}\usr\bin;${PATH}" # old
PATH="${PATH};${RTOOLS40_HOME}\usr\bin" # new
同样,我不完全确定 这个 可能有什么后果,但它为我解决了 gdata
。
也许单独调整 PATH
也可以解决问题(没有我先做的 ftype
特技),但我不能再测试了。
我的推荐:
- 先调整
PATH
。
- 如果
gdata
仍然抱怨 ftype
,请设置 ftype
。
