为什么 Flutter 只能以超级用户身份运行？

Question

我最近尝试在我的 Macbook Pro（2015 年初，MacOS v10.13.6）上安装Flutter框架。我将包解压到/Applications目录中，并在 bash 配置文件中创建了相应的路径。但是，当flutter doctor以默认用户身份在终端上运行命令时，我遇到以下错误。

shlock: open(/Applications/flutter/bin/cache/shlock2538): Permission denied\nshlock: open(/Applications/flutter/bin/cache/shlock2540): Permission denied\nshlock: open(/Applications/flutter/bin/cache/shlock2542): Permission denied\nshlock: open(/Applications/flutter/bin/cache/shlock2544): Permission denied\nshlock: open(/Applications/flutter/bin/cache/shlock2546): Permission denied\nshlock: open(/Applications/flutter/bin/cache/shlock2548): Permission denied\nshlock: open(/Applications/flutter/bin/cache/shlock2550): Permission denied\n

当我flutter doctor使用超级用户权限 ( sudo) 运行该命令时，它能够运行，并且得到以下终端输出。

我更喜欢以默认用户身份运行 Flutter，而不是使用超级用户权限（即使我收到框架发出的以默认用户身份运行的警告）。

谁能帮助我了解如何修复此错误并开始使用默认用户帐户运行 Flutter 框架？谢谢。

Answer 1

我尝试按照 G\xc3\xbcnter Z\xc3\xb6chbauer 的回答更改 flutter 的位置。但是，flutter 仍然需要超级用户权限。所以，我就这样直接给了他们

\n\n

sudo chown -R $USER /Users/yourUser/flutter/\n

\n\n

这对我来说效果很好。基本上，向用户授予特定文件夹的权限。

Answer 2

Flutter 在其安装目录中维护了多个文件，如 Dart 快照文件，这就是为什么/Applications默认情况下仅对 root 用户具有写入权限的 目录不是安装 Flutter 的好地方。

/Users/yourUser/flutter没有 root 权限也能正常工作。
