salt error : "TypeError: coercing to Unicode: need string or buffer, bool found"

Question

运行 salt 命令出现以下错误：盐“”state.sls 出口工作

有人可以帮助解决这个问题吗？

检查此页面 --> https://github.com/saltstack/salt/issues/12400。他们在谈论类似的问题。

Answer 2

Salt 不会抛出适当的错误消息，这就是所有混乱的原因。在我的例子中，data.sls 有一个包名称条目，该条目已被另一个 salt 脚本从运行此脚本之前的位置删除。

每当您收到此错误时，给定路径中应该缺少 file/directory。

如果 salt 抛出带有准确消息的错误，那就太好了。

Answer 3

在我的例子中，我打印了多个 table 的值。在第一个 table 中，它具有以下架构：

| ORDINAL_POSITION | COLUMN_NAME   | DATA_TYPE | CHARACTER_MAXIMUM_LENGTH | IS_NULLABLE |
|                1 | DateTimeStamp | datetime  | NULL                     | NO          |
|                2 | DataVal       | nvarchar  | -1                       | NO          |

这些打印没有问题。然后在第二个 table 中，它有这个架构：

| ORDINAL_POSITION | COLUMN_NAME   | DATA_TYPE | CHARACTER_MAXIMUM_LENGTH | IS_NULLABLE |
|                1 | DateTimeStamp | datetime  | NULL                     | NO          |
|                2 | DataVal       | bit       | NULL                     | NO          |

一旦到达第二个 table 的打印行，它就会抛出这个 coercing to Unicode: need string or buffer, bool found error:

        for myValue in tableValues:
            print str(myValue.dateTimeStamp)+', '+myValue.dataVal

所以为了避免这种情况，我只是将所有值都转换为字符串：

        for myValue in tableValues:
            print str(myValue.dateTimeStamp)+', '+str(myValue.dataVal)
