自从Travis now supports building on Windows（至少在某种程度上），我正在玩一个基于Windows机器的Unity项目。在尝试对Travis配置进行各种更改时，我有两个版本能够安装Unity（但没有做任何其他事情）。一旦我准备好尝试使用统一构建配置，Chocolatey无法下载Unity。
我个人（通过Travis奴隶）是否达到了每日下载限制（我总是得到相同的奴隶IP）？或者这是几个人经常通过Travis下载团结的结果？
由于我能够通过日志中提供的链接手动下载文件，因此我将排除统一服务器问题作为原因。
这是失败的Travis日志：

虽然确实在Chocolatey.org上有一个新的速率限制功能（这是在on the 26th November 2018上启用的），但是当它在播放时返回的HTTP错误代码是429，而不是403.结果，我没有认为这是导致你出现问题的原因。
有关于403 HTTP状态代码here的故障排除文章。我建议跟进那里的建议，这可能是由于以下一些原因造成的：
- 您有一个需要配置的代理
- 它在您的组织中被阻止
- 我们打破了一些东西（这是最不可能的原因）
- CloudFlare由于原因阻止了您的IP（99％的时间，这是问题）
- Chocolatey社区团队可能因过度使用而阻止访问 - 请参阅过多使用细节
