Error installing composer in windows PHP Startup: Unable to load dynamic library 'ext\json.so'

Question

I get this error while installing composer in Windows.

The PHP exe file you specified did not run correctly:
C:\xampp\php\php.exe

The php.ini used by your command-line PHP is: C:\xampp\php\php.ini

A setting in your php.ini could be causing the problem: Either the 'extension_dir' value is incorrect or the dll does not exist.

Program Output:
Warning: PHP Startup: Unable to load dynamic library 'ext\json.so' - The specified module could not be found.
 in Unknown on line 0

Answer 1

我不得不从php.ini中删除此行，这就是问题所在

extension=json.so
