自制程序:无法符号链接，/usr/local/bin不可写
问题描述：
在安装tig时，HomeBrew在安装依赖项时显示以下问题:
While installing tig, HomeBrew is displaying the following issues while installing a dependency:
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/a2x

You can try again using:
brew link asciidoc
答
遵循 Alex的答案我能够解决此问题问题;似乎这不是特定于要安装的软件包的问题，而是homebrew文件夹的权限.
Following Alex's answer I was able to resolve this issue; seems this to be an issue non specific to the packages being installed but of the permissions of homebrew folders.
sudo chown -R `whoami`:admin /usr/local/bin
对于某些软件包，您可能还需要对/usr/local/share或/usr/local/opt执行此操作:
For some packages, you may also need to do this to /usr/local/share or /usr/local/opt:
sudo chown -R `whoami`:admin /usr/local/share
sudo chown -R `whoami`:admin /usr/local/opt
