在具有空间的路径中调用可执行文件时出现问题 [英] issue when calling executable in a path that has space

问题描述

我刚在新的Microsoft Windows 7计算机上安装了R，并且在使用命令行时出现以下错误:

I just installed R on a new Microsoft Windows 7 computer and I am running in the following error when using command line:

"C:\Program Files\R\R-3.3.2\bin\Rscript.exe" --version  
'C:\Program' is not recognized as an internal or external command,

可运行的程序或批处理文件.

operable program or batch file.

请注意，我在路径周围的引号上方添加了空格.并且我已经在系统路径中添加了:

Note that I have added above the quotes around the path with a space. And that I have added in the system path:

;C:\Program Files\R\R-3.3.2\bin\

有趣的是:

1. 如果我仅将其命名为Rscript.exe --version，它将给出相同的错误，这非常奇怪:如果找到它，为什么它不能运行它！ 我能找到的唯一解释是，在寻找Rscript.exe依赖项时发生错误
2. 我还注意到"C:\Program Files\R\R-3.3.3\bin\x64\Rscript.exe" --version可行(文件夹...\bin和...\bin\x64都有可执行的Rscript.exe)

1. if I just call this Rscript.exe --version it gives the same error, which is very weird: if it finds it, why can't it run it!?! The only explanation I can find is that the error occurs when looking for a dependency of Rscript.exe
2. I also noticed that this works "C:\Program Files\R\R-3.3.3\bin\x64\Rscript.exe" --version (both folders ...\bin and ...\bin\x64 have an executable Rscript.exe)

最后，我确认这是一个R特定的问题，因为我可以在同一命令行界面中调用我在Program Files子文件夹中尝试过的所有其他可执行文件！

Finally I confirm it is an R specific question as all other executables I tried in a subfolder of Program Files can be called through the same command line interface!

推荐答案

我一直在尝试复制您的问题，但在您的问题中发现了一件事:您提到这不起作用:

I have been trying to replicate your issue and I found one thing in your question: You mention that this does not work:

"C:\Program Files\R\R-3.3.2\bin\Rscript.exe" --version  
'C:\Program' is not recognized as an internal or external command,

但是这样做:

"C:\Program Files\R\R-3.3.3\bin\x64\Rscript.exe" --version

似乎在适用的示例中使用R-3.3.3，而在无效的示例中使用R-3.3.2.

It seems that you are using R-3.3.3 in the example that works and R-3.3.2 in the example that does not.

所以我认为，如果将其更改为

So I would assume that if you change it to

"C:\Program Files\R\R-3.3.3\bin\Rscript.exe" --version  

应该可以.
