在我的MacMini电脑上运行El Capitan操作系统时,我无法再使用brew命令。我遇到了以下错误:
/usr/local/Library/Homebrew/config.rb:34:in `initialize': no implicit conversion of nil into String (TypeError)
from /usr/local/Library/Homebrew/config.rb:34:in `new'
from /usr/local/Library/Homebrew/config.rb:34:in `<top (required)>'
from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:54:in `require'
from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:54:in `require'
from /usr/local/Library/Homebrew/global.rb:18:in `<top (required)>'
from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:54:in `require'
from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:54:in `require'
from /usr/local/Library/brew.rb:10:in `<main>'
/usr/local的权限正确。
我没有改变的config.rb文件看起来像这样:
def cache
if ENV["HOMEBREW_CACHE"]
Pathname.new(ENV["HOMEBREW_CACHE"]).expand_path
else
# we do this for historic reasons, however the cache *should* be the same
# directory whichever user is used and whatever instance of brew is executed
home_cache = Pathname.new("~/Library/Caches/Homebrew").expand_path
if home_cache.directory? && home_cache.writable_real?
home_cache
else
Pathname.new("/Library/Caches/Homebrew").extend Module.new {
def mkpath
unless exist?
super
chmod 0775
end
end
}
end
end
end
HOMEBREW_CACHE = cache
undef cache
# Where brews installed via URL are cached
HOMEBREW_CACHE_FORMULA = HOMEBREW_CACHE+"Formula"
unless defined? HOMEBREW_BREW_FILE
HOMEBREW_BREW_FILE = ENV["HOMEBREW_BREW_FILE"] || which("brew").to_s
end
# Where we link under
HOMEBREW_PREFIX = Pathname.new(ENV["HOMEBREW_PREFIX"])
# Where .git is found
HOMEBREW_REPOSITORY = Pathname.new(ENV["HOMEBREW_REPOSITORY"])
HOMEBREW_LIBRARY = Pathname.new(ENV["HOMEBREW_LIBRARY"])
HOMEBREW_CONTRIB = HOMEBREW_REPOSITORY/"Library/Contributions"
# Where we store built products
HOMEBREW_CELLAR = Pathname.new(ENV["HOMEBREW_CELLAR"])
HOMEBREW_LOGS = Pathname.new(ENV["HOMEBREW_LOGS"] || "~/Library/Logs/Homebrew/").expand_path
HOMEBREW_TEMP = Pathname.new(ENV.fetch("HOMEBREW_TEMP", "/tmp"))
unless defined? HOMEBREW_LIBRARY_PATH
HOMEBREW_LIBRARY_PATH = Pathname.new(__FILE__).realpath.parent.join("Homebrew")
end
HOMEBREW_LOAD_PATH = HOMEBREW_LIBRARY_PATH
使用brew、brew doctor、brew update等命令时都会出现相同的错误。
有任何想法,可能出了什么问题吗?
