当我尝试在 Windows 上运行 Perl one-liner 时，为什么会在 EOF 之前的任何位置找到字符串终止符“'”，在 -e line 1”？

Why am I getting "Can't find string terminator "'" anywhere before EOF at -e line 1" when I try to run a Perl one-liner on Windows?
提问by R.D
I am trying to run the following on Windows with 5.14.2
我正在尝试使用 5.14.2 在 Windows 上运行以下内容
C:\Perl>perl -e 'print "Hello World \n"' Can't find string terminator "'" anywhere before EOF at -e line 1.
What am I missing?
我错过了什么？

You're missing a decent shell with sane and well-defined quoting rules. On Windows, only the double quote is considered a quote, and the escaping rules are poorly defined and inconsistent. Try:
您缺少一个体面的外壳，它具有合理且定义明确的引用规则。在 Windows 上，只有双引号被认为是引号，并且转义规则定义不明确且不一致。尝试：
perl -e "print qq{Hello World \n}"
I strongly recommend avoiding anything but the very simplest one-liners on Windows. (Another problem with Windows one-liners is that the Windows shell doesn't expand wildcards. If you use *.txton the command line, it'll look for a file named literally *.txt. You'll run into that later.)
我强烈建议避免使用 Windows 上最简单的单行代码以外的任何内容。（Windows one-liners 的另一个问题是 Windows shell 不会扩展通配符。如果您*.txt在命令行上使用，它会查找字面命名的文件*.txt。稍后您会遇到它。）
On Windows, what you typed is equivalent to:
在 Windows 上，您键入的内容相当于：
perl -e "'print" "Hello World \n'"
That is, the code Perl is trying to execute is 'printwith @ARGVcontaining the single string Hello World \n'. (That's not a newline, that's a backslash followed by n).
也就是说，Perl的正试图执行的代码是'print用@ARGV含有单个字符串Hello World \n'。（那不是换行符，而是反斜杠后跟n）。

On Windows, the quotation marks should be reversed. So, rather than:
在 Windows 上，引号应该颠倒。所以，而不是：
C:\Perl>perl -e 'print "Hello World \n"'
it should be:
它应该是：
C:\Perl>perl -e "print 'Hello World \n'"

I also found this to work. I am using Windows 7 using c:\Windows\system32\cmd.exe
我也发现这有效。我正在使用 Windows 7 使用c:\Windows\system32\cmd.exe
perl -e "$a=2; print(\"$a \n \");"
I'm using the escape slash in my print statement to get the quotes to appear \"
我在我的打印语句中使用转义斜杠来让引号出现 \"

On Windows the following command works:
在 Windows 上，以下命令有效：
perl -e "print \"Hello world\""
perl -e "print \"Hello world\""
