问题描述
我正在使用Powershell.我的问题是我的文件路径(在本地计算机上不存在)中带有撇号.Powershell将此视为单引号，因此给了我以下错误:字符串缺少终止符:'.我以为我可以使用反引号对单引号进行转义，但这给了我我同样的错误.
I am working with Powershell. My issue is that my file path (which does not exist on a local computer) has an apostrophe in it. Powershell is seeing this as a single quote, so it is giving me the following error: The string is missing the terminator: '. I thought that I could escape the single quote using a backtick, but that gave me the same error.
当我执行第一行代码时，不会发生该错误，并且我甚至不需要反引号.我什至可以看到变量的内容与我正在使用的文件路径匹配.只有当我执行invoke-expression部分时，它才会给我错误.
The error does not occur when I am doing the first line of code, and I don't even need the backtick for that part. I can even see that the contents of the variable matches up with the file path that I am using. It is only when I am doing the invoke-expression part that it is giving me the error.
我正在使用 https://docs.microsoft.com/zh-cn/powershell/module/microsoft.powershell.utility/invoke-expression?view=powershell-7 ，所以我认为代码就是问题所在.
I am using https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/invoke-expression?view=powershell-7, so I don't think the second line of the code is the problem.
我的代码在下面列出:
$code = "\\example\example\John_Doe`'s_Folder\example.ps1"
invoke-expression -command $code
我也尝试将整个文件路径包装在双引号和单引号中，但是我的程序也不喜欢.我无法删除撇号，因为我们有100多个直接指向John_Doe's_Folder的系统.
I have also tried wrapping the entire file path in double-quotes and single-quotes, but my program did not like that either. I can't remove the apostrophe as we have over a hundred of systems that are directing to John_Doe's_Folder.
推荐答案
Invoke-Expression 通常应该避免；绝对不要使用它来调用脚本或外部程序.
在您的情况下，只需使用& ，呼叫操作符通过存储在变量 $ code 中的路径来调用脚本(请参见(了解背景信息)，在这种情况下，嵌入式'根本不需要转义:
In your case, simply use &, the call operator to invoke your script via the path stored in variable $code (see this answer for background information), in which case the embedded ' needs no escaping at all:
$code = "\\example\example\John_Doe's_Folder\example.ps1"
& $code
关于您尝试过的事情:
"\\ example \ example \ John_Doe's_Folder \ example.ps1" 变成以下 verbatim 字符串内容:
"\\example\example\John_Doe`'s_Folder\example.ps1" turns into the following verbatim string content:
\\example\example\John_Doe's_Folder\example.ps1
也就是说，通过PowerShell对"..." 字符串文字本身的解析，将`删除了 ，其中的>`充当转义符；由于转义序列`'没有特殊含义，因此`只是已删除.
That is, the ` was removed by PowerShell's parsing of the "..." string literal itself, inside of which ` acts as the escape character; since escape sequence `' has no special meaning, the ` is simply removed.
要使`能够生存"，您需要转义`字符.本身，您可以使用``:
For the ` to "survive", you need to escape the ` char. itself, which you can do with ``:
"\\example\example\John_Doe``'s_Folder\example.ps1"
