使用自制软件安装icu4c版本63

Question

我试图启动psql，但失败了

psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

当我使用postgres-D /usr/local/var/postgres时，得到以下错误：

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.63.dylib
  Referenced from: /usr/local/bin/postgres
  Reason: image not found
[1]    2559 abort      postgres -D /usr/local/var/postgres

在libicui18n.63.dylib上的快速搜索显示我需要版本63的icu4clib。然而brew list icu4c说我有64.2版本。

我尝试了两种brew安装icu4c 63

有人能帮忙吗？提前感谢。

Answer 1

这应该更容易。

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/e7f0f10dc63b1dc1061d475f1a61d01b70ef2cb7/Formula/icu4c.rb

Answer 2

如@dingusjh所说，但是如果brew抱怨icu4c已经安装，您应该尝试提取，请使用重新安装命令而不是安装。然后，完整的命令将是：

brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/e7f0f10dc63b1dc1061d475f1a61d01b70ef2cb7/Formula/icu4c.rb

Answer 3

解决方案：

1. cd到Homebrew的公式目录

• Intel

  cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula
  

  cd $(brew --prefix)/Library/Taps/homebrew/homebrew-core/Formula
  

  git log --follow icu4c.rb
  

  git checkout -b icu4c-63 e7f0f10dc63b1dc1061d475f1a61d01b70ef2cb7
  

  brew reinstall ./icu4c.rb
  

  brew switch icu4c 63.1
  

  git checkout master

  • 自制安装公式的特定版本

  对于那些多次使用此功能的用户，奖励：

  # zsh
  function hiicu63() {
    local last_dir=$(pwd)
  
    cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula
    git checkout icu4c-63
    brew reinstall ./icu4c.rb
    brew switch icu4c 63.1
    git checkout master
  
    cd $last_dir
  }
