我也遇到过同样的问题。这是因为证书的私钥在您的机器上不存在。

If you are now using a new machine and download the certificate from website: You can export the certificate from the old machine and then import on the new machine. If you share the developer account with someone: You ask the account owner to send you an invitation and become a team member of that account. Then you can create your own certificate from scratch. If you don't want to handle all these sh*t: Just revoke the certificate on website and delete the copy on your local machine. Then request a new one. This should be the ultimate way for solving such issue.

你试过重启你的Mac和设备吗?蹩脚的回答，但我总是先试一下。

昨天也遇到了同样的问题。现在，在签署到开发人员门户之后，对于每个无效的配置概要都有一个按钮“Renew”。更新和下载更新后的配置文件似乎都能正常工作，所以问题肯定解决了:)

更新:你可能需要联系苹果来获得一个“更新”按钮，或者他们删除了它——解决方案是下载它并添加到钥匙链，不需要更新。

你需要:

1)私钥和公钥。

你的钥匙链上有这个符号

2)由这些密钥的签名请求生成的证书

3)连接到该证书的配置文件

假设你换了电脑，想重新设置Xcode配置文件。你是怎么做到的?

Open Xcode, press ctrl + O to open the Organizer, and delete all provisioning profiles you might have installed already. Open keychain access, and create a signing request which you save to file (when you create the request, a private and public key is created in your keychain). Create/Update a certificate in the provisioning portal by sending apple this signing request Download and install the newly created certificate. Revoke your provisioning profiles and update them with the new certificate. Download and install the newly updated provisioning profiles.

Because I keep coming back to this question, I will leave my answer here for the solution that works for me. It turns out that for a same public/private key developer identifier of me, it's installed twice in my keychain. Both have private key. But when I compare, one is private key of me within my developer organisation, and another one is private key of me as a personal developer. It turns out Xcode keeps trying using the wrong key. Removing the wrong duplicate key solves all the problem. Hey future me, check this one first next time!

“这是苹果门户网站的一个漏洞。他们在配置配置文件中缺少一个必要的字段。他们在2009年6月16日晚些时候修复了这个错误。”
