推荐答案

由于Apple的系统完整性保护，您收到此错误消息.系统完整性保护包括对系统以下部分的保护:

You get this error message because of Apple's System Integrity Protection. System Integrity Protection includes protection for these parts of the system:

/System
/usr
/bin
/sbin
Apps that are pre-installed with OS X

第三方应用程序和安装程序可以继续编写的路径和应用程序包括:

Paths and apps that third-party apps and installers can continue to write to include:

/Applications
/Library
/usr/local

这意味着您可以简单地在/usr/local/bin中创建符号链接(它仍在您的$PATH中)，但不能在/usr/bin中创建.

This means that you can simply create a symbolic link in /usr/local/bin (it's still in your $PATH), but not in /usr/bin.

此外，您可以通过以下方式禁用系统完整性保护(我强烈建议您这样做):

Also, you can disable System Integrity Protection (I strictly advise against that) by:

1. 点击菜单.
2. 选择重新启动...
3. 按住Command-R引导进入恢复系统.
4. 单击实用工具"菜单，然后选择终端".
5. 键入csrutil disable，然后按回车键.
6. 关闭终端应用程序.
7. 单击菜单，然后选择重新启动....
