CocoaPods 安装

 

1. 更新了系统，发现 $ sudo gem install cocoapods 安装报错。

2. 安装 coreutils即可 $ brew install coreutils 

 

$ brew install coreutils

==> Pouring coreutils-8.32.catalina.bottle.1.tar.gz
==> Caveats
Commands also provided by macOS have been installed with the prefix "g".
If you need to use these commands with their normal names, you
can add a "gnubin" directory to your PATH from your bashrc like:
  PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"
==> Summary
🍺  /usr/local/Cellar/coreutils/8.32: 476 files, 12.5MB

 

3. 重新装就正常了

4. pod setup 失败

 

$ pod setup
/Users/WeepYan/.rvm/rubies/ruby-2.6.0/lib/ruby/gems/2.6.0/gems/cocoapods-1.10.0/lib/cocoapods/executable.rb:93: warning: Insecure world writable dir /usr/local/mysql in PATH, mode 040777
Setup completed

 

5. 解决方案 https://www.cnblogs.com/huaida/p/12701080.html

 

二、CocoaPods使用 pod install 问题

a) 原因是本地库没有该版本的第三方库

 

 

b) 使用命令 $pod install --repo-update 更新本地库

 

c) 再次执行正常

 

三、查看pod源并移除trunk源

1. 使用 $ pod --version 查看版本

2. 使用 $ pod repo list 查看源

3. 使用 $ pod repo remove trunk 移除 trunk 源

 

 

四、ruby警告问题 warning: Insecure world writable dir /usr/local/mysql in PATH, mode 040777

1. 产生场景

　　不仅仅是pod场景，其它场景也一样。

$ pod search MB
/Users/WeepYan/.rvm/rubies/ruby-2.6.0/lib/ruby/gems/2.6.0/gems/cocoapods-1.10.0/lib/cocoapods/executable.rb:93: warning: Insecure world writable dir /usr/local/mysql in PATH, mode 040777
Setup completed

2. 原因分析

　　报这个错的本质原因：文件夹 /usr/local/mysql 是需要不可写的，但是目前是可写入的，所以有写入安全隐患，所以报警告。

3. 解决方案

　　命令行输入 sudo chmod go-w /usr/local/mysql 并输入电脑密码即可消除警告。

$ sudo chmod go-w /usr/local/mysql
Password:

 　　再次执行 pod search MB 发现警告没有了，很多跟pod相关的警告都可以类似解决。

4. sudo chmod go-w 命令分析

　　sudo 是管理员权限

　　chmod 修改文件或文件夹权限

　　g 是group，表示组权限

　　o 是other，表示其它用户

　　- 删除权限

　　+ 增加权限

　　w 写权限

　　r 读权限

　　x 可执行权限

5. 恢复警告

　　如果要恢复警告，可执行命令 sudo chmod go+w /usr/local/mysql  这样警告就又出现了。

 

 

　　当然咱们的目的是消除警告，测试只是为了更好的理解命令。

6. 参考文档

　　理解chown||chmod go-w

　　linux语句：chmod g-w aut.txt这句话是什么意思？
