報錯
flutter項目在運行到ios 模擬器的時候報錯：
Warning: CocoaPods not installed. Skipping pod install.
還有

Xcode’s output:

ld: framework not found Flutter
clang: error: linker command failed with exit code 1 (use -v to see

Could not build the application for the simulator.
Error launching application on iPhone XR.
具體報錯沒記錄，一開始也沒想着會有這麼麻煩。
提示
官方給出了兩個提示執行命令：
brew install cocoapods
pod setup
這個其實在一開始配環境執行flutter doctor的結果之後也給了提示，也是配置mac環境的條件。
但是本來項目是可以運行到ios模擬器的，新項目也是可以運行的，但是最近項目改動較多，無從查起，沒辦法只能硬着頭皮解決了。
在網上搜了一圈，並沒有相關的解決方案，沒辦法，站不了巨人的肩上了，只能自己摸索了。
思路一
按照指示在終端執行brew install cocoapods，等了好一會，開始出現下載
==> Downloading https://homebrew.bintray.com/bottles/cocoapods-1.7.5.mojave.bottle.tar.gz
==> Downloading from https://akamai.bintray.com/5a/5a70fd60007975ce224824b1a8852ba9124faa6753061d0ecc024be4cebd6e8b?__gda__=exp=1565624237~hmac=b87d5d0111b49f600da053951890
下載到百分之幾的時候就失敗了，然後又重試，結果在百分之六十多的時候又失敗了，應該是要fq，國內速度較慢。
然後又開始在網上搜CocoaPods的安裝教程，搜了一圈下來，看着都麻煩。
思路二
然後我嘗試在Android Studio自帶的terminal中直接執行brew install cocoapods，默認是在項目根目錄執行的，
yechaodeMacBook-Pro:wanandroid_flutter yechao$ brew install cocoapods
會有error提示
Error: Another active Homebrew update process is already in progress.
Please wait for it to finish or terminate it to continue.
但是可以下載，而且速度挺快的，
==> Downloading https://homebrew.bintray.com/bottles/cocoapods-1.7.5.mojave.bottle.tar.gz

下載完成之後在執行 pod setup，又是一頓下載，這個要等一會了。
yechaodeMacBook-Pro:wanandroid_flutter yechao$ pod setup
Setting up CocoaPods master repo
$ /usr/local/bin/git clone https://github.com/CocoaPods/Specs.git --progress -- master

完了之後再次嘗試運行到ios模擬器，
ok，運行成功！
