Cocoapods installation failed
Complete error message trying to install my problem
Using alamofire needs to be based on cocoapods, but there are many problems in the process of trying to install cocoapods. It has failed for a long time. Finally, the installation is successful only after the on-demand broadcast of the leaders in the group. In fact, sometimes the solution to the problem is very simple. I hope this blog can help you.

Try to install
Steps: first install homebrew, then update ruby, and then install cocoapods
Note: many online blogs require the installation of RVM, in fact, RVM does not have to be </ font>, but is just a way to update ruby
The blog of the boss is directly quoted here. The reference is as follows:
-
Mac OS system install homebrew Mac OS system update Ruby Mac OS system restart cocoapods
My question
Generally speaking, the installation can be basically completed according to the above process. Here is my problem. My problem is that the version of ruby is too low. Before successful installation, my version is 2.6.3p62. I will update the ruby version to 3.0.2_ After 1, execute: sudo gem install - N/usr/local/bin cocoapods and the installation is successful!
The main problem here is that the latest ruby is updated through homebrew, but it is not necessarily the latest, so the installation fails.
(in fact, in the article of the boss cited above, it is written to configure the latest Ruby environment variables, but I didn’t read it carefully at the beginning)
Here are two ways to configure Ruby environment variables:
Method 1:
echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc
Method 2:
echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
Check whether the ruby version is updated through Ruby - V and try to install it later
Basically, the above four modifications can solve the project running in the debug mode. It has not been tried on the real machine for the time being. It should also directly modify the configuration in the release.
