Xcode 11.1安装组件时失败,报错信息为 An unknown error occurred. See the install log for more details.
解决方案
- This problem has once again appeared in Xcode 11.1 and is caused by an invalid certificate that expired some day in October 2019.
- You can work around the problem by temporarily changing the system date to before the certificate expiration date.
- In the case of Xcode 11, set the system date to Oct 3, 2019, run Xcode, then change the date back after the components have installed.
译文:
- 这个问题再次在Xcode 11.1出现,是有个证书在2019年的10月份某天过期引起的。
- 你可以通过暂时把系统日期修改到过期的日期之前来解决。
- 在Xcode 11这个版本下,设置系统日期为2019年10月3日,然后运行Xcode,再安装组件,(就可以安装成功了),完成之后再把系统日期改回正常状态。
详细操作截图如下
- 1.系统设置->日期与时间
- 2.点击解锁
- 3.去掉自动设置日期与时间,修改为10月3日之前(随便)
- 4.打开Xcode, 点击Install即可安装成功。
- 5.将系统日期勾回自动即可。
