使用 XOAUTH2 在 debian linux 上使用 mbsync (isync) 同步 gmail

Question

我正在尝试使用以下命令将我的邮件从 gmail 同步到我的本地邮件服务器MB同步。但我不断收到错误Error: SASL(-4): no mechanism available: No worthy mechs found

这是我的.mbsyncrc文件：

#IMAP server you wish to copy mails from.
IMAPAccount original
Host imap.gmail.com
User [email protected]
AuthMechs XOAUTH2
Pass access_token_recieved_from_google
UseIMAPS yes
CertificateFile /etc/ssl/certs/ca-certificates.crt

# The IMAP server you wish to copy mails to.
IMAPAccount target
Host local.mail.server.host
User local_user
Pass  somepass
AuthMechs LOGIN
UseIMAPS yes
CertificateFile /etc/ssl/certs/ca-certificates.crt

# Link IMAP server to remote used below. Note Account is set to     'original' now -- we'll be set it to 'target' later!
IMAPStore my-remote
Account original

# The local storage we'll be using. Note the trailing slash at the end of the Path!
MaildirStore my-local
Path ~/mail/
Inbox ~/mail/INBOX/

# This is where the magic happens. Note Sync is set to 'Pull' now -- we'll     set it to 'Push' later!
Channel my-channel
Master :my-remote:
Slave :my-local:

mbsync --版本isync 1.2.1

看起来 mbsync 无法识别XOAUTH2关键字AuthMechs。如果我将 AuthMech 类型更改为LOGIN，我会收到invalid credentials错误。 （有道理，我用身份验证令牌代替密码）。

有任何想法吗？
