在 VS Code 终端(Windows Powershell)中编译时遇到问题 [英] Having trouble compiling in VS Code terminal, which is Windows Powershell

问题描述

当我右键单击运行代码"并在我的用户设置中的终端中运行时，我收到这些错误.

<块引用>

在行:1 字符:63+ ... "c:\Users\Josh\Documents\Programming\Learning to Program\" &&g++ exe ...+ ~~令牌&&"在此版本中不是有效的语句分隔符.在行:1 字符:99+ ... \学习编程\" && g++ Exercise36.cpp -o Exercise36 && "c:\Use ...+ ~~令牌&&"在此版本中不是有效的语句分隔符.在行:1 字符:102+ ... ercise36 &&"c:\Users\Josh\Documents\Programming\Learning to Program\ ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~表达式只能作为管道的第一个元素.在行:1 个字符:160+ ...

直到今天，我一直在编译，我做了一些谷歌搜索并开始在终端中输入我自己的命令，而不仅仅是运行代码.

我开始用 -and 替换 && 并遇到不同的问题.这就是命令现在的样子.

"c:\Users\Josh\Documents\Programming\Learning to Program\" -and g++ Exercise36.cpp -o Exercise36 -and "c:\Users\Josh\Documents\Programming\Learning to Program\练习36

这是我得到的错误.

我使用的是 GNU 开源编译器，这是我在编译时遇到的第一个问题，因为我意识到必须在编译之前进行保存.我正在运行一个简单的字符串，它将从 C++ Primer 程序的终端读取的字符串中的所有字符更改为 X.任何帮助将不胜感激.

解决方案

我也遇到了同样的问题，我认为是新的 VS Code 1.35 版本引起的.我尝试降级到 1.34 并再次编译和运行 c++.

旧版本似乎使用不同的命令运行代码:

<块引用>

"cd $dir ; if ($?) { g++ $fileName -o $fileNameWithoutExt } ; if ($?) { .\\$fileNameWithoutExt}"

在您的情况下，它看起来像:

<块引用>

cd "c:\Users\Josh\Documents\Programming\Learning to Program\" ;if ($?) { g++ Exercise36.cpp -o Exercise36 } ;if ($?) { .\Exercise36}

对我来说，使用这个命令在新的 VS 版本中编译和运行也是有效的.

When I right click Run code, and have run in terminal on in my user settings I get these errors.

    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : InvalidEndOfLine

I have been compiling fine up until today, and I did some googling and started typing my own commands into the terminal instead of just running code.

I started replacing the && with -and and get a different problem. This is what the command looks like now.

"c:\Users\Josh\Documents\Programming\Learning to Program\" -and g++ Exercise36.cpp -o Exercise36 -and "c:\Users\Josh\Documents\Programming\Learning to Program\"Exercise36

This is the error I get.

    + CategoryInfo          : InvalidArgument: (:) [Set-Location], ParameterBindingException
    + FullyQualifiedErrorId : AmbiguousParameter,Microsoft.PowerShell.Commands.SetLocationCommand

I am using the GNU open source compiler, this is the first issue I have had with compiling since I realized you have to save before you compile. I am running a simple string that changes all the characters to X from a string that is read from terminal from C++ Primer program. Any help would be appreciated.

解决方案

I had the same problem, I believe it is caused by the new VS code version 1.35. I tried downgrading to 1.34 and compiling and running c++ worked again.

The old version seems to run the code with a different command:

"cd $dir ; if ($?) { g++ $fileName -o $fileNameWithoutExt } ; if ($?) { .\\$fileNameWithoutExt}"

in your case it would look like:

cd "c:\Users\Josh\Documents\Programming\Learning to Program\" ; if ($?) { g++ Exercise36.cpp -o Exercise36 } ; if ($?) { .\Exercise36}

For me using this comand compiling and running works in the new VS version aswell.
