UnauthorizedAccessException：访问路径 [ios/Macos Mojave/Unity 19.2.0] 无法构建项目

Question

上周我能够在完全相同的 Macbook pro 上构建完全相同的项目，但现在我不再是，我不明白为什么。

现在当我第一次打开项目时（我主要在 Windows 计算机上为这个项目的 android 版本工作，使用 mac 只是为了进行构建）它说：

解析包时出错：

 One or more packages could not be added to the local file system:
    com.unity.collab-proxy: EPERM: operation not permitted, unlink '/Users/dondoo/Desktop/Grove_Anniversary/Library/PackageCache/com.unity.collab-proxy@1.2.16/CHANGELOG.md'
    com.unity.ext.nunit: EPERM: operation not permitted, unlink '/Users/dondoo/Desktop/Grove_Anniversary/Library/PackageCache/com.unity.ext.nunit@1.0.0/.gitlab-ci.yml'
    com.unity.ide.rider: EPERM: operation not permitted, unlink '/Users/dondoo/Desktop/Grove_Anniversary/Library/PackageCache/com.unity.ide.rider@1.0.8/.editorconfig'

    com.unity.textmeshpro: EPERM: operation not permitted, unlink '/Users/dondoo/Desktop/Grove_Anniversary/Library/PackageCache/com.unity.textmeshpro@2.0.1/.gitlab-ci.yml'

然后当我重新打开它时它崩溃了，但是当我尝试构建时，我得到了这个错误：

我已尝试重新导入所有内容。 我尝试过不同版本的统一。 我无法在 Windows 电脑上构建，因为 firebase 不允许从不使用 MacOsX 的计算机构建 ios。

Answer 1

简短的回答是，如果 Unity 正在运行，删除库目录是安全的。在机器之间共享项目时，我实际上将Library、Temp、obj 和Logs 添加到我的.gitignore 文件中。

我确实在您的日志中注意到 /Users/dondoo 和 /Users/builduser。您还想确保需要访问您的 Unity 项目的任何用户帐户都可以获取它（即：如果您以 builduser 运行 Unity，但该文件夹只能由 dondoo 访问，那么您将度过一段糟糕的时光)。由于您在自动生成的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 实例打开项目，您可能会遇到问题（例如：您正在编辑为 dondoo 但随后 builduser 尝试进行自动构建）。

希望我的第一个答案能解决它，但如果没有，还有一些事情要检查！

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。
