上周我能够在完全相同的Macbook Pro上构建完全相同的项目，但现在我不再了，我不明白为什么。
现在，当我第一次打开该项目时(我主要在该项目的Android版本的Windows计算机上工作，仅使用mac进行构建(，它说：
解析包时出错：
One or more packages could not be added to the local file system:

com.unity.textmeshpro: EPERM: operation not permitted, unlink '/Users/dondoo/Desktop/Grove_Anniversary/Library/PackageCache/com.unity.textmeshpro@2.0.1/.gitlab-ci.yml'
之后它崩溃了，然后当我重新打开它时没有问题，但是当我尝试构建时，我收到此错误：

我尝试重新导入所有内容。 我尝试了不同版本的团结。 我无法在Windows PC上构建，因为Firebase不允许从未使用MacOsX的计算机进行iOS构建。
简短的回答是，如果 Unity 正在运行，删除库目录是安全的。实际上，在机器之间共享项目时，我会向.gitignore文件添加Library、Temp、obj和Logs。
我确实注意到您的日志中有/Users/dondoo和/Users/builduser。您还需要确保需要访问您的 Unity 项目的任何用户帐户都可以获取它(即：如果您以builduser方式运行 Unity，但该文件夹只能由dondoo访问，您将遇到困难(。由于自动生成的Library目录中似乎有问题，因此可能是这种情况。此外，如果您当前通过另一个 Unity 实例打开了项目(例如：您正在按dondoo进行编辑，但随后builduser尝试进行自动生成(，则可能会出现问题。
希望我的第一个答案可以解决它，但如果没有，有一些事情需要检查！

我通过删除项目附带的库和临时文件夹并让 Unity 重建它们来解决问题。
