Question

我正在尝试通过laravel连接到PostgreSQL数据库，以便让php工匠迁移，但是我收到了错误

[PDOException]找不到驱动程序

查看类似的问题，在php.ini中启用扩展程序，但未解决我的问题，仍然给我同样的错误。

在我的代码的其他部分，我使用数据库，我可以添加记录，所以我认为我的设置数据库正确。我不明白这个错误。

Database.php文件：

<?php return [ 
      'fetch' => PDO::FETCH_CLASS, 
      'default' => env('DB_CONNECTION', 'pgsql'), 
      'connections' => [ 
             'pgsql' => [ 
                  'driver' => 'pgsql', 
                  'host' => env('DB_HOST', 'localhost'), 
                  'database' => env('DB_DATABASE', 'forge'), 
                  'username' => env('DB_USERNAME', 'forge'), 
                  'password' => env('DB_PASSWORD', ''), 
                  'charset' => 'utf8', 'prefix' => '', 
                  'schema' => 'public', 
              ], 
        ], 
        'migrations' => 'migrations', 
  ]; ?>

检查您是否有import subprocess import sys import shutil import os class NetworkConfiguration: def __init__(self): self.ntype="" self.hostname="" self.domain="" self.pdns="" self.sdns="" self.ip="" self.netmask="" self.gway="" self.files=["/etc/sysconfig/network/ifcfg-eth0", "/etc/sysconfig/network/routes", "/etc/resolv.conf", "/etc/HOSTNAME" ] def writeIntoFile(self,filename,s,mode): f=open(filename,mode) f.write(s) f.close() def buildString(self,filename): ret_str="" if filename == self.files[0] : ret_str="DEVICE=eth0" ret_str+="\n"+"STARTMODE=auto" ret_str+="\n"+"BOOTPROTO=" if self.ntype=="s": ret_str+="static" else: ret_str+="dhcp" ret_str+="\n"+"USERCONTROL=no" ret_str+="\n"+"ONBOOT=yes" if self.ntype=="s": ret_str+="\n"+"IPADDR="+self.ip ret_str+="\n"+"NETMASK="+self.netmask elif filename==self.files[1]: if self.ntype=="s": ret_str="defualt "+self.gway+" - -" elif filename==self.files[2]: ret_str="search "+self.domain ret_str+="\n"+"nameserver "+self.pdns if self.sdns!="": ret_str+="\n"+"nameserver "+self.sdns elif filename==self.files[3]: ret_str=self.hostname+"."+self.domain return ret_str def runProcess(self,args): p=subprocess.Popen(args,stdout=subprocess.PIPE,stderr=subprocess.PIPE) return p.communicate() #------------------------Class Ends Here--------------------------------------- nCog=NetworkConfiguration() # Recieving arguments from commmand line. #sequence is: network_type,hostname,domain,primary_dns,ip,netmask,gateway,secondry_dns # note : IP, Netmask, gateway are not required in case of DHCP. try: nCog.ntype=sys.argv[1] if nCog.ntype=="s" and len(sys.argv)<8: raise Exception("Too few arguments passed for static configuration!!!") elif nCog.ntype=="d" and len(sys.argv)<5: raise Exception("Too few arguments passed for DHCP configuration!!!") elif nCog.ntype!="s" and nCog.ntype!="d": raise Exception("Not a valid network type!!!") nCog.hostname=sys.argv[2] nCog.domain=sys.argv[3] nCog.pdns=sys.argv[4] if nCog.ntype=="s": nCog.ip=sys.argv[5] nCog.netmask=sys.argv[6] nCog.gway=sys.argv[7] if len(sys.argv)==9: nCog.sdns=sys.argv[8] elif len(sys.argv)==6: nCog.sdns=sys.argv[5] except Exception, e: print(e) # Writing network configurations into the appropriate files. for f in nCog.files: ret_str=nCog.buildString(f) nCog.writeIntoFile(f,ret_str,"w") # Setting the hostname o, e=nCog.runProcess(['hostname',nCog.hostname]) # restart the network o, e=nCog.runProcess(['service','network restart']) print("restarting the network:\n------------------------------------") print("output: "+o+"\n error: "+e) # Adding gateway ip to the routing table in case static ip is assigned. print os.system("sudo ip route add default via %s" % (nCog.gway))延期。
