Question

我正在尝试使用Ansible运行Vagrant时遇到问题。以下是我在Windows 7上尝试在终端（git bash）中运行vagrant up或vagrant provision时遇到的错误：

ERROR! Unexpected Exception: Non-hexadecimal digit found
to see the full traceback, use -vvv
Ansible failed to complete successfully. Any error output should be
visible above. Please fix these errors and try again.

之所以发生这种情况，是因为Ansible-vault文件.vault_pass不是十六进制（它是一个字符串，无法更改）。在我的同事的计算机上它正常工作，但在我的同事上它没有。

.vault_pass文件中有问题的字符串看起来像DBAKWeG3KOr3jKjBDbAz。

我猜这个问题与Python有关，但我不确定，我也不知道如何修复它。

当我尝试添加-vvv时，这是重新开始的：

ERROR! Unexpected Exception: Non-hexadecimal digit found
the full traceback was:

Answer 1

当编码文件包含回车符（\ r）符号时，可能会发生此问题。

如果您通过git获取文件，则应正确配置git - 将core.eol = lf设置为.gitconfig

Answer 2

它与加密文件末尾的Windows行结尾有关。只需将最后一行切换到Unix并保存文件即可。

Answer 3

以防万一有人遇到相同的问题，当尝试手动解密直接从YAML文件（或从ansible-vault encrypt_string的输出中复制）的变量时，我遇到了这个问题

例如：

加密字符串：

echo -n 'all that is gold does not glitter' | ansible-vault encrypt_string
Reading plaintext input from stdin. (ctrl-d to end input)
!vault |
          $ANSIBLE_VAULT;1.1;AES256
          61626566613637386434386364376236636636646263386561336463386132626335386335356463

          3062636437636664363039383436306535303939323535353163

尝试解密：

echo '$ANSIBLE_VAULT;1.1;AES256
          61626566613637386434386364376236636636646263386561336463386132626335386335356463

[WARNING]: There was a vault format error in -: Vault format unhexlify error:

ERROR! Vault format unhexlify error: Non-hexadecimal digit found for -

要解决此问题，只需删除开头的YAML缩进空格：

echo '$ANSIBLE_VAULT;1.1;AES256
61626566613637386434386364376236636636646263386561336463386132626335386335356463

要添加另一个变体，这是如何发生的：拱形字符串末尾的尾随空格也可以这样做：

Temperature

根据偶数/奇数你也可能得到 mysql_pw: !vault | $ANSIBLE_VAULT;1.1;AES256 35336630636134383938626366353162326236363966353535356361373465616364383336366536 6630373462316336333830643331376464633961643633380a623863373966323432646236306239 36326465343239343766363936653631643761646562306530363262633262323966623530373664 3239376534303565340a623262646132623033383964366438633964303633363430373463633033 3164 < spaces here
