Question

我想安装 mysqlclient(Python 是用 conda 安装的)。我明白了

conda install mysqlclient
Fetching package metadata .........
Solving package specifications: .


PackageNotFoundError: Package not found: '' Package missing in current linux-64 channels: 
  - mysqlclient

Close matches found; did you mean one of these?

    mysqlclient: mwclient, slackclient, pysmbclient

我在 Ubuntu 16.04,64 位上。

This is with apt search
apt search mysqlclient

但我仍然很困惑，我不能从 python 运行 mysqlclient。

  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'mysqldb'

Answer 1

导入的模块名称是MySQLdb，而不是mysqldb。即使在不区分大小写的文件系统上，Python 也是区分大小写的语言。
