mysqlclient低层依赖一些C库，你这里报的原因是编译的C库有问题，应该是没有正确安装，可尝试卸载重新安装。

  怎么安装呢？

• 咚咚呛 回复 提问者 x3x #2

  conda环境使用conda uninstall xxx卸载然后conda install xxx安装即可。你也可以百度搜索一下相关内容，不懂的时候多搜索了解。

  (python36) root@iZwz9at7nu2rprqr8qtn2oZ:~/webapp# conda install mysqlclient
  Fetching package metadata .........
  
  PackageNotFoundError: Package missing in current linux-64 channels: 
    - mysqlclient
  
  Close matches found; did you mean one of these?
  
      mysqlclient: hs2client
  
  (python36) root@iZwz9at7nu2rprqr8qtn2oZ:~/webapp# 
  这怎么做呢？
