brew安装git Mac中的错误：无法符号链接/ man / man5 / gitattributes.5

Question

尝试使用

在我的Mac系统（High Sierra 10.13.3）上更新git

brew install git

给出输出

$ brew install git
==> Downloading https://homebrew.bintray.com/bottles/git-2.16.2.high_sierra.bottle.tar.gz
######################################################################## 100.0%
==> Pouring git-2.16.2.high_sierra.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/man/man5/gitattributes.5
/usr/local/share/man/man5 is not writable.

You can try again using:
  brew link git
==> Caveats
Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

zsh completions and functions have been installed to:
  /usr/local/share/zsh/site-functions

Emacs Lisp files have been installed to:
  /usr/local/share/emacs/site-lisp/git
==> Summary
  /usr/local/Cellar/git/2.16.2: 1,496 files, 34.5MB

但是，您可以看到brew link步骤存在问题。试图通过运行来修复它

brew link git
brew link --overwrite git
brew link --force git

给出相同的错误

Linking /usr/local/Cellar/git/2.16.2... 
Error: Could not symlink share/man/man5/gitattributes.5
/usr/local/share/man/man5 is not writable.

任何人都有这样的经历并设法修复它吗？

Answer 1

如果您在High Sierra上，Arraylist是不可写的（可能是由于SIP的更改），但是内容是可写的。因此，您只需要修改其他答案中的命令即可仅将目标放在以下目录中：

Integer [] ia = {1,2,3,4};
System.out.println("Array : "+Arrays.toString(ia));
List<Integer> list1 = new ArrayList<Integer>(Arrays.asList(ia));  // new ArrayList object is created , no connection between existing Array Object
list1.add(5);
list1.add(6);
list1.remove(0);
list1.remove(0);
System.out.println("list1 : "+list1);
System.out.println("Array : "+Arrays.toString(ia));

Answer 2

您必须使用以下命令修复权限：

sudo chown -R "$USER":admin /usr/local
sudo chown -R "$USER":admin /Library/Caches/Homebrew

如果您是系统中唯一的自制用户，那么效果很好。如果第三方工具正在等待/usr/local上的其他权限，则可能会导致问题。但是，我使用这些设置多年没有问题。有关详细信息，请参阅How to fix homebrew permissions?。

但为此，您必须有权管理计算机。在“系统偏好设置”中 - ＆gt;用户＆amp;群组，您的用户应选中“允许用户管理此计算机”复选框。
