cocoapods安装realm报错

一、

Installing Realm 2.7.0 (was 2.1.2)

[!] /bin/bash -c

set -e

sh build.sh cocoapods-setup

xcrun: error: invalid DEVELOPER_DIR path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

解决办法：命令行运行如下指令

xcode-select --install

二、

[!] /bin/bash -c

set -e

sh build.sh cocoapods-setup

./scripts/swift-version.sh: line 59: [: =: unary operator expected

No version of Xcode found that supports Swift 3.1

解决办法：- xcode >> preferences >> locations >> CommandLineTools 一般选最新的
