问题描述
我正在构建一个 Flutter 应用程序，并在其中使用 Facebook 开发日志记录。我使用了 gci -File -Recurse | Select-Object -Property @{
label = 'Git commit'
expr = { Invoke-Expression "git log -1 --format:format=`"%s`" -- $($_.FullName)" }
},@{
label = 'Size(KB)'
expr = { [string]::Format("{0:0.00}",$_.Length/1KB) }
},LastWriteTime,FullName
和 Flutter_facebook_login: ^3.0.0 插件，这个插件在 android 中工作，但在 ios 中它给了我以下错误：
Flutter_facebook_auth: ^3.3.2我的颤动医生 -v：
[!] CocoaPods Could not find compatible versions for pod "FBSDKCoreKit":
In Podfile:
Flutter_facebook_auth (from `.symlinks/plugins/Flutter_facebook_auth/ios`) was resolved to 2.0.0,which depends on
FBSDKCoreKit (~> 9.1.0)
Flutter_facebook_login (from `.symlinks/plugins/Flutter_facebook_login/ios`) was resolved to 0.0.1,which depends on
FBSDKCoreKit (~> 5.5)

但无法解决
那我现在该怎么办？
解决方法
要解决此问题，请按照以下步骤操作：
#include <stdlib.h> #include <unistd.h> #include <sys/types.h> #include <sys/ipc.h> #include <sys/shm.h> #define SIZE 1024 #define KEY 0x1234 typedef struct{ int sharedNum; int counter1; int counter2; } SharedMem; int main (void) { SharedMem *memory; int shmid; if ((shmid=shmget(KEY,SIZE,0644 | IPC_CREAT))==-1) { perror ("shmget error!"); exit (1); } else { memory=shmat(shmid,NULL,0); if (memory==(void*)-1) { perror ("shamt error!"); exit (1); } else { memory->sharedNum=1; } } int procPID = fork(); for (int i=0; i<5; i++){ if (fork()==0) { printf ("Forking in for-cyklus\n"); exit (0); } } if (shmdt(memory)==-1) { perror ("shmdt error!"); exit (-1); } if (shmctl (shmid,IPC_RMID,0)==-1) { perror ("shmctl error!"); exit (1); } return 0;- 运行
flutter clean（用于删除rm -f ios/Podfile.lock文件） -
ios/Podfile.lock并点击cd ios（更新所有依赖项） pod update
你可以试试这个，
首先清理 Flutter，然后从 ios 文件夹中删除 .symlinks、Pods、Podfile.lock 和 Runner.xcworkspace。
然后运行 pub get。
告诉我它是否有效。
