无法安装mysqlclient

5 人关注

我在django框架中使用python3.8，为此我必须安装mysqlclient。但是，当我尝试安装时，却出现了错误

pip3 install mysqlclient
像这样的输出是错误的。

            I think
            
             libffi-dev
            
            你的系统/服务器中缺少libary文件。
使用下面的命令来检查库的安装与否
           
           apt-cache search libffi
安装libffi-dev 
sudo apt-get install -y libffi-dev
pip3 install mysqlclient
sudo apt-get install python-dev default-libmysqlclient-dev
sudo apt-get install python3-dev
pip install mysqlclient


           
            
             
              
               
                
                 包libffi-devel-3.0.13-18.el7.x86_64已经安装。但还是出现了错误...


           
            
             
              
               
                
                 sudo apt-get install python-dev default-libmysqlclient-dev sudo apt-get install python3-dev pip install mysqlclient


           
            
             
              
               
                
                 上述先决条件我已经从以下地方安装了
                 
                  pypi.org/project/mysqlclient
                 
                 . But still error is coming..


           
            
             
              
               
                
                 在用pip3替换pip后，方法2对我来说是有效的。

                There for you have to update your pip
               
               
                Next you have to run this
                
                 yum install libffi-deve
                
                or
                
                 sudo dnf install libffi-devel
                
               
               
                After that run
                
                 pip3 install mysqlclient
                
                or
                
                 sudo yum install python36u-devel mysql-devel
                
                to install mysqlclient.


           
            
             
              
               
                
                 MariaDB-client已经安装了。但除了mysql驱动，我还需要mysqlclient。我没有coda。


           
            
             
              
               
                
                 我正在使用centos 7


           
            
             
              
               
                
                 Do I need to set
                 
                  libffi
                 
                 有什么具体地点吗？


           
            
             
              
               
                
                 你所说的是正确的，是Python的错误。所以我重新安装了Python并编译了它。然后它就工作了。


          
           
            
             
              
               
                我的问题已经解决了。当我安装python-3.8.0时，我没有编译它，这就是问题所在。我使用的是Centos7，所以我到终端的根部，先安装Python的先决条件，再安装它。
               
               # sudo yum install gcc openssl-devel bzip2-devel libffi-devel
download latest version
#wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz
Now extract the downloaded package.
Compile Python Source
#cd Python-3.8.0
#sudo ./configure --enable-optimizations
make altinstall is used to prevent replacing the default python binary file /usr/bin/python.
#sudo make altinstall
remove downloaded source archive file from your system
#sudo rm Python-3.8.0.tgz
Check Python Version
#python3.8 -V 
Then I could be able to install mysqlclient by
