CocoaPods更新出错和问题解决过程_error: error installing rubygems-update: there are

通常我们做iOS移动端开发的，使用CocoaPods来管理第三方库。如果要更新第三方库，一般是在XCode工程所在目录下，执行pod install操作。
这一次我像往常一样去更像第三方库，但是出错了！！！
需要更像Cocoapods，旧的版本是1.4.0。我们要更新到1.7.5。

RubyGems installed the following executables:
/Users/jam/.rbenv/versions/2.1.0/bin/gem

Ruby Interactive (ri) documentation was installed. ri is kind of like man
pages for ruby libraries. You may access it like this:
ri Classname
ri Classname.class_method
ri Classname#instance_method
If you do not wish to install this documentation in the future, use the
–no-document flag, or set it as the default in your ~/.gemrc file. See
‘gem help env’ for details.

Warning! PATH is not properly set up, ‘/Users/jam/.rvm/gems/ruby-2.4.1/bin’ is not at first place.
Usually this is caused by shell initialization files. Search for ‘PATH=…’ entries.
You can also re-add RVM to your profile by running: ‘rvm get stable --auto-dotfiles’.
To fix it temporarily in this shell session run: ‘rvm use ruby-2.4.1’.
To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.
Warning, new version of rvm available ‘1.29.9-next’, you are using older version ‘1.29.3’.
You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc

keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
/usr/local/etc/openssl/certs

and run

openssl is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have openssl first in your PATH run:
echo ‘export PATH="/usr/local/opt/openssl/bin:$PATH"’ >> ~/.bash_profile

For compilers to find openssl you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl/lib"

openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,

readline is keg-only, which means it was not symlinked into /usr/local,

In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.
