现象

工程使用了 cocoaPods，打包时遇到了如下报错：

解决方案

更改cocoaPods脚本文件 Pods工程中的Target Support Files/Pods-xxx-frameworks.sh

readlink "${source}"

改为

readlink -f "${source}"

排查过程

1. 升级cocoaPods指最新版，但并没有什么用，可能他们还没来得及更新

2. rsync命令，可以用来同步文件，和cp、mv类似。检查出参入参了。把多余的可配置项去掉，于是得到了：

1
2
3

rsync \ 
"../../../IntermediateBuildFilesPath/UninstalledProducts/iphoneos/AFNetworking.framework" \
"/Users/xxx/Library/Developer/Xcode/DerivedData/xxx/Build/Intermediates.noindex/ArchiveIntermediates/xxx/InstallationBuildProductsLocation/Applications/xxx.app/Frameworks"

等等！第一个路径参数为什么是个相对路径？

3. 查cocoaPods脚本，以下为报错代码

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

   if [ -r "${BUILT_PRODUCTS_DIR}/$1" ]; then local source="${BUILT_PRODUCTS_DIR}/$1" elif [ -r "${BUILT_PRODUCTS_DIR}/$(basename "$1")" ]; then local source="${BUILT_PRODUCTS_DIR}/$(basename "$1")" elif [ -r "$1" ]; then local source="$1" fi local destination="${TARGET_BUILD_DIR}/${FRAMEWORKS_FOLDER_PATH}" if [ -L "${source}" ]; then echo "Symlinked..." source="$(readlink "${source}")" fi if [ -d "${source}/${BCSYMBOLMAP_DIR}" ]; then # Locate and install any .bcsymbolmaps if present, and remove them from the .framework before the framework is copied find "${source}/${BCSYMBOLMAP_DIR}" -name "*.bcsymbolmap"|while read f; do echo "Installing $f" install_bcsymbolmap "$f" "$destination" rm "$f" done rmdir "${source}/${BCSYMBOLMAP_DIR}" fi # Use filter instead of exclude so missing patterns don't throw errors. echo "rsync --delete -av "${RSYNC_PROTECT_TMP_FILES[@]}" --links --filter \"- CVS/\" --filter \"- .svn/\" --filter \"- .git/\" --filter \"- .hg/\" --filter \"- Headers\" --filter \"- PrivateHeaders\" --filter \"- Modules\" \"${source}\" \"${destination}\"" rsync --delete -av "${RSYNC_PROTECT_TMP_FILES[@]}" --links --filter "- CVS/" --filter "- .svn/" --filter "- .git/" --filter "- .hg/" --filter "- Headers" --filter "- PrivateHeaders" --filter "- Modules" "${source}" "${destination}"

那现在只需要追踪source的赋值。

source第一次赋值的结果是一个软连接。

接下来肯定会走下面判断中的代码去拿真实文件的路径，进行第二次赋值。

1

if [ -L "${source}" ]; then
  echo "Symlinked..."
  source="$(readlink "${source}")"
fi

真相大白，readlink "${source}" 得到的结果就是一个相对路径。

查一下readlink命令用法，发现它有个-f的可配置参数，拿到的是绝对路径。也就是最后我们用的解决方法。
