我想删除mac中的php：
/private/etc/ sudo rm -rf php-fpm.conf.default php.ini php.ini.default
/usr/bin/ sudo rm -rf php php-config phpdoc phpize
/usr/include sudo rm -rf php
/usr/lib sudo rm -rf php
/usr/sbin sudo rm -rf php-fpm
/usr/share sudo rm -rf php
/usr/share/man/man1 sudo rm -rf php-config.1 php.1 phpize.1
/usr/share/man/man8 sudo rm -rf php-fpm.8
当我跑步时
sudo rm -rf php php-config phpdoc phpize
发生：
rm: php: Operation not permitted
rm: php-config: Operation not permitted
rm: phpize: Operation not permitted
有人可以帮助我吗？多谢！
当我在终端中输入时，我在 MAC 中安装了最新的 Angular 6.0.4：
ng new happiness
展示：
Schematic input does not validate against the Schema: {"dryRun":false,"version":"6.0.4","skipGit":false,"skipInstall":false,"linkCli":false,"commit":true,"newProjectRoot":"projects","inlineStyle":false,"inlineTemplate":false,"routing":false,"prefix":"app","style":"css","skipTests":false} Errors:Data path "" should NOT have additional properties(dryRun).
谁能告诉我？非常感谢
在 Solidity 中，有没有办法将 int 转换为 string ？
例子：
pragma solidity ^0.4.4;
contract someContract {
uint i;
function test() pure returns (string) {
return "Here and Now is Happiness!";
}
function love() pure returns(string) {
i = i +1;
return "I love " + functionname(i) + " persons" ;
}
}
什么是函数名？谢谢！

normalization_layer = layers.Rescaling(1./255)

如何修复它？
