WDA问题混总

大家好，又见面了，我是你们的朋友全栈君。

1. unable to access DB:

多个xcode线程在跑，杀掉xcode， 杀掉xcodebuild进程 ， clean

2. WebDriverAgentLib codesign失败

环境：
mac 10.14.5
xcode 10.3

报错： Command Codesign failed with a nonzero exit code… The bundle identifier for WebDriverAgentRunner-Runner.app couldn’t be read

背景： 更换了provision file， 导致WebdriverAgetnLib codesign失败。而使用xcode IDE 运行是没问题的。

解决： 重启MAC。 猜测， 可能系统有关， xcodebuild命令执行时没有对变动后的描述文件识别，迟钝，未生效。

3. WebDriverAgentLib codesign failure.

library no loaded.
No suitable image found


背景：更改了bundleid和provision file。 xcode IDE 运行WDA正常， xcodebuild 命令行报错。

解决： 对WebDriverAgentLib的info.plist 设置bundleid与WebDriverAgentRunner一致，且 product bundle identifier也一致，不要空着。 code signing identity – Debug – Any ios sdk指定为具体的iphone developer: who (xxxx)

4. dyld_shared_cache_extract_dylibs failed

第一种方法：

• go to window-devices and simulators

• select the unrunable device and right click, then choose unpair

• now this is the crucial part, your device will ask for trust automatically, dont click trust

• focus back to the device panel, left click the + and add the device, click next, it will ask you to tap the “trust” IN THE PANEL

• now you can tap the “trust” in your phone, the panel will say phone added successfully

第二种方法：

• go to ~/Library/Developer/Xcode/iOS DeviceSupport/13.2/Symbols/System/Library/Caches/com.apple.dyld

• create empty file if it is not there – .processed_dyld_shared_cache_arm64e

• restart xcode and enjoy!

第三种方法：

• unpair device (like carusd.ljt did), quit xcode

• delete /Users/{username}/Library/Developer/Xcode/iOS DeviceSupport folder

• rerun xcode, reconnect iphone, wait for it prepared, run the app.

5. Could not connect to lockdownd, error code -19

如果只是单个手机连不上，显示该错误。 去到/var/db/lockdown，看下有没有该手机的.plist，没有则从其他连过该手机的Mac电脑该目录下拷贝过来。解决。

如果所有手机都连不上， 卸载升级重装libimobileservice
brew uninstall ideviceinstaller -g
brew uninstall libimobiledevice -g
brew install –HEAD libimobiledevice -g
brew install ideviceinstaller -g
sudo chmod -R 777 /var/db/lockdown

6. 执行./autogen.sh,报错No package ‘libplist’ found

编译usbmuxd源码，执行 ./autogen.sh 报错

checking for libplist >= 1.11... no
configure: error: Package requirements (libplist >= 1.11) were not met:

No package 'libplist' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables libplist_CFLAGS
and libplist_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

可以在终端输入

export libplist_LIBS=/usr/local/opt/libplist/lib/libplist-2.0.dylib
export libplist_CFLAGS=/usr/local/opt/libplist/lib/libplist-2.0.a

或者在.bash_profile里配置
然后再执行./autogen.sh
