看看cocoapod版本号
$pod --version Ignoring ffi-1.9.23 because its extensions are not built. Try: gem pristine ffi --version 1.9.23 1.6.1
-
1.6.1是我的版本号,改成你目前的,卸载老版本
$sudo gem uninstall cocoapods -v 1.6.1 Password:需要输入密码 Successfully uninstalled cocoapods-1.6.1 $sudo gem uninstall cocoapods-core -v 1.6.1 Successfully uninstalled cocoapods-core-1.6.1
-
安装1.6.0版本
$sudo gem install cocoapods -v 1.6.0
-
如果报错
ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /usr/bin directory.
-
使用如下
$sudo gem install cocoapods -v 1.6.0 -n /usr/local/bin Fetching: cocoapods-core-1.6.0.gem (100%) Successfully installed cocoapods-core-1.6.0 Fetching: cocoapods-1.6.0.gem (100%) Successfully installed cocoapods-1.6.0 Parsing documentation for cocoapods-core-1.6.0 Installing ri documentation for cocoapods-core-1.6.0 Parsing documentation for cocoapods-1.6.0 Installing ri documentation for cocoapods-1.6.0 Done installing documentation for cocoapods-core, cocoapods after 6 seconds 2 gems installed
