由于需要最新版本的Xcode工具，就升級(jí)了電腦系統(tǒng)到10.15.4 (19E287)。安裝了最新Xcode11.4安裝后發(fā)現(xiàn) cocoapods使用出現(xiàn)異常。需要重新安裝cocoapods.

安裝

因?yàn)镸ac電腦自帶Ruby環(huán)境，我們就只需打開終端直接安裝就可以了。如果出現(xiàn)ruby版本過低的情況可以先更新ruby。

1.查看當(dāng)前ruby版本

ruby -v

2.升級(jí)ruby環(huán)境(升級(jí)ruby需要借助rvm,需要先安裝rvm)

1.curl -L  https://get.rvm.io | bash -s stable
2.source ~/.rvm/scripts/rvm
3.rvm -v

如果要升級(jí)rvm使用命令

rvm get stable

3.安裝ruby

1.rvm list known

結(jié)果為

# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p330]
[ruby-]1.9.3[-p551]
[ruby-]2.0.0[-p648]
[ruby-]2.1[.10]
[ruby-]2.2[.10]
[ruby-]2.3[.8]
[ruby-]2.4[.6]
[ruby-]2.5[.5]
[ruby-]2.6[.3]
[ruby-]2.7[.0-preview1]
ruby-head

此時(shí)可以根據(jù)自己的需要安裝指定版本的ruby。

rvm install 2.6.3

本文相關(guān)操作是在ruby[ruby-]2.6[.3]完成的。

4.更換鏡像源(如果已經(jīng)處理可忽略此步驟)

sudo gem update --system

gem sources --remove https://rubygems.org/

gem sources --add https://gems.ruby-china.com/

查看更換結(jié)果

gem sources -l

*** CURRENT SOURCES ***

https://gems.ruby-china.com

5.安裝cocoapods 10.11后命令 之前的命令為(sudo gem install cocoapods)

sudo gem install -n /usr/local/bin cocoapods

此時(shí)如果出現(xiàn)以下錯(cuò)誤，原因是因?yàn)樵诎惭bxcode的時(shí)候保留了之前的版本，當(dāng)前系統(tǒng)上有兩個(gè)版本的xcode.

處理步驟
5.1 把最近安裝的xocde拖到中，注意名稱要為xcode默認(rèn)名。

5.2 終端執(zhí)行命令

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

5.3 再次執(zhí)行安裝命令

sudo gem install -n /usr/local/bin cocoapods

安裝中...

此時(shí)等待命令執(zhí)行完畢就可以了。

完成后搜索測(cè)試出現(xiàn)以下錯(cuò)誤。

終端執(zhí)行命令 即可

pod repo remove trunk

此時(shí)就可以正常搜索查詢檢索了。

總結(jié):

1.本文的場(chǎng)景是升級(jí)mac系統(tǒng).
2.安裝并保留了多個(gè)xcode.
3.pod search xx 命令長時(shí)間卡住沒有正確返回.
