1. After updating Mac systems, pod search error
After updating the system, sometimes using the pod search the following error appears. I was in search mj
At this time we can execute directly pod repo remove trunk remove the trunk source, pod search on all normal!
The reason for this problem is generally the local trunk.
But then again we encounter the following problems
This problem is solved in the previous 1.8.0 release us directly pod setup but after 1.8.0 there is no use.
I had good pod setup times useless, and later on directly after a pod init file, add a common pod inside the library, pod install it automatically updates the trunk to the local library.
2. Uninstall cocoapods
First uninstall cocoapods we can use the following code
sudo gem uninstall cocoapods
But sometimes the following error.
Error: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.
This time we need to use this one statement the.
sudo gem uninstall -n /usr/local/bin cocoapods
The next step is to install a nice view local resources cocoapods
gem list --local | grep cocoapods
cocoapods-core (1.8.4) cocoapods-deintegrate (1.0.4) cocoapods-downloader (1.2.2) cocoapods-plugins (1.0.0) cocoapods-search (1.0.0) cocoapods-stats (1.1.0) cocoapods-trunk (1.4.1) cocoapods-try (1.1.0) 这些事我检索出来的文件，接下来就是一一删除。
sudo gem uninstall cocoapods-core sudo gem uninstall cocoapods-deintegrate sudo gem uninstall cocoapods-downloader sudo gem uninstall cocoapods-plugins sudo gem uninstall cocoapods-search sudo gem uninstall cocoapods-stats sudo gem uninstall cocoapods-trunk sudo gem uninstall cocoapods-try
这样也就彻底卸载了cocoapods
