今天pod search 一個(gè)庫(kù)時(shí)發(fā)現(xiàn)搜索到的版本比github上的最新版本舊警医,于是采用下面的命令更新Cocoapods的庫(kù)
pod repo update master --verbose
執(zhí)行后卻報(bào)了下面的錯(cuò)誤:
Updating spec repo `master`
[!] Failed to connect to GitHub to update the CocoaPods/Specs specs repo - Please check if you are offline, or that GitHub is down
這是為何呢,明明不久前剛剛更新Cocoapods為1.3.1版本啊喷屋。
搜索才發(fā)現(xiàn)是Github在不久之前的2018年2月23號(hào)移除了一些低加密標(biāo)準(zhǔn)協(xié)議,包括TLSv1/TLSv1.1仇穗,diffie-hellman-group1-sha1奠衔,diffie-hellman-group14-sha1谆刨,相關(guān)鏈接在這里:Weak cryptographic standards removed
這就意味著Mac系統(tǒng)對(duì)應(yīng)的openssl也需要更新。
這里提供了全套升級(jí)辦法归斤,搬運(yùn)過(guò)來(lái):
$ which openssl
/usr/bin/openssl
$ openssl version
OpenSSL 0.9.8zh 14 Jan 2016
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$ brew update
$ brew install openssl
$ brew upgrade openssl
`` If you need to have this software first in your PATH run: echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
$ echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
$ source ~/.bash_profile
$ which openssl
/usr/local/opt/openssl/bin/openssl
$ openssl version
OpenSSL 1.0.2n 7 Dec 2017
$ brew install rbenv ruby-build
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
$ source ~/.bash_profile
$ rbenv install --list

$ gem install cocoapods -n /usr/local/bin
$ which pod
/usr/local/bin/pod
$ pod --version
1.4.0
完成上面一系列操作后痴荐,Cocoapods將會(huì)升級(jí)到最新的1.4.0版本。再執(zhí)行pod repo update master --verbose
就沒(méi)有問(wèn)題了官册。
