错误如下：
The following build commands failed:
PhaseScriptExecution [CP-User]\ Generate\ Specs /Users/qiaohao/Library/Developer/Xcode/DerivedData/AwesomeProject-aqjmxeejdieamfaqbvvwftijujzz/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/FBReactNativeSpec.build/Script-46EB2E00014D80.sh (in target 'FBReactNativeSpec' from project 'Pods')
(1 failure)可能的原因
1. 项目路径包含了空白字符
2. 使用了nvm来进行node安装
nvm的解决办法是去修改项目的node_modules/react-native/scripts/find-node.sh文件，将以下内容注释：
if [[ -s "$HOME/.nvm/nvm.sh" ]]; then
# shellcheck source=/dev/null
. "$HOME/.nvm/nvm.sh"
elif [[ -x "$(command -v brew)" && -s "$(brew --prefix nvm)/nvm.sh" ]]; then
# shellcheck source=/dev/null
. "$(brew --prefix nvm)/nvm.sh"
fi
