当我在Cygwin终端上运行此命令 'php -r "readfile('https://getcomposer.org/installer');" | php' 时,终端会触发以下错误:
Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:
The json extension is missing.
Install it or recompile php without --disable-json
The phar extension is missing.
Install it or recompile php without --disable-phar
The iconv OR mbstring extension is required and both are missing.
Install either of them or recompile php without --disable-iconv
然而,所有这些扩展都在php.ini文件中启用。我正在使用XAMPP。
