解决PHP Warning: putenv() has been disabled for security reasons in phar:

在使用composer的时候报一下错误，这是因为php禁用了putenv() 函数

PHP Warning: putenv() has been disabled for security reasons in phar:///usr/bin/composer/vendor/composer/xdebug-handler/src/Process.php on line 97

Warning: putenv() has been disabled for security reasons in phar:///usr/bin/composer/vendor/composer/xdebug-handler/src/Process.php on line 97 PHP Warning: putenv() has been disabled for security reasons in phar:///usr/bin/composer/src/Composer/Util/Platform.php on line 78

Warning: putenv() has been disabled for security reasons in phar:///usr/bin/composer/src/Composer/Util/Platform.php on line 78

如果使用宝塔

就去宝塔的php配置里删掉禁用的函数putenv

修改php.ini配置

为了避免修改错误！请在修改前备份原来的putenv文件！ 修改php的配置文件，php.ini 找到disable_function这个地方，把putenv去掉即可。
