使用以下命令安装 csvkit 后

$ sudo -HE pip install --upgrade -e git+git://github.com/wireservice/csvkit.git@master#egg=csvkit

并尝试.csv按如下方式导入 a：

csvsql --db mysql://root:root@127.0.0.1:3306/jira_test --insert --table bugs_temp --no-constraints --overwrite --create-if-not-exists --no-inference --blanks bugs_temp.csv

我收到以下错误

（这个答案可能有点不完整。我没有经验csvsql，所以我把它变成了一个维基。）

csvkit 取决于agate-sql，取决于sqlalchemy。_ _

sqlalchemy包含这行代码：

    "VARCHAR requires a length on dialect %s" % self.dialect.name

引用这个答案，似乎“<em>您需要为所有字符串指定长度” 。

这意味着您不能使用该--no-constraints选项：

  --no-constraints      Generate a schema without length limits or null
                        checks. Useful when sampling big tables.
