错误：在新升级的macOS Mojave上运行Vim时，pathname包含空字节

Question

我最近升级到macOS Mojave 10.14.1，当使用原生的Terminal或iTerm时，vim命令似乎被打破了。错误看起来像

dudeOnMac:~ freddy$ vim file
dyld: Library not loaded: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/libruby.2.0.0.dylib
  Referenced from: /usr/local/bin/vim
  Reason: image not found

我发现这个SuperUser帖子并没有完全解决问题。其他一些建议是从头开始重新安装Vim。所以我做了一个

brew update
brew upgrade vim

但是留下了以下错误

==> Upgrading vim 
Error: The following formula
  [#<Dependency: "python" []>, #<Options: []>]
cannot be installed as binary package and must be built from source.
Install the Command Line Tools:
  xcode-select --install

所以我进去并按照上面的建议安装了xcode，但现在又留下了一个新的错误

Error: An unexpected error occurred during the `brew link` step
The formula built, but is not symlinked into /usr/local
pathname contains null byte

Answer 1

我试图密切关注homebrew维护者页面中的步骤 - Error: pathname contains null byte和Broken symlink detection needed，这并没有解释确切的问题。

我进去跑了brew doctor并试图解决一个问题。首先是创建不存在的目录/usr/local/sbin并添加正确的权限

sudo mkdir -p /usr/local/sbin
sudo chown -R $(whoami) /usr/local/sbin

即使在此运行brew upgrade vim显示相同的错误

错误：pathname包含空字节

初始链接中的一个页面提示一些破坏的符号链接可能导致问题，我进去查看/usr/local/opt，其中utils链接到来自Cellar的路径，但readline被破坏而没有指向任何地方

lrwxr-xr-x  1 freddy  admin    26B Apr 18  2017 readline -> 

这似乎是罪魁祸首，使用它删除它

rm -rf /usr/local/opt/readline

并做了一个新的brew upgrade vim现在安装了所需的依赖项并成功安装了vim。我对awk有同样的问题，我不得不使用brew upgrade gawk修复。
