无法在Windows 8.1上运行任何Perl脚本

Question

I installed Active Perl 5.20 and also Strawberry Perl 5.20 after uninstalling Active Perl.

In both cases, when I open cmd and type 'perl' I get:

Unknown Unicode option letter ':'.

This error also prevents all scripts from running on my Windows 8.1 installation.

I uninstalled Perl and did a fresh install and it still doesn't work.

Are there dependencies that I need to install? I googled the error but the results pertain to Linux installations where the script specified something wrong. But I get this error when I even try to use any perl command line or script. So my problem is not a faulty script.

Answer 1

That is the error message you get from using an invalid value for the -C command-line option. At a guess I'd say you have the PERL_UNICODE environment variable set to a string that contains a colon : .

Take a look at Command Switches in perldoc perlrun for more detail on this.

Answer 2

I too had this problem on windows 8.1 . The problem is that, once on installation, .pl files are not automatically recognized by Perl engine. So please select a .pl file and right click and say open with and set the default program to C\\perl\\bin\\ inside it click perl.exe and recognize it. Once this is done your perl works flawlessly.
