小编Vue*_*ion的帖子

我的语言文件：

AccountNotifications: {\n  createdWithName: 'Account \xc2\xab{account}\xc2\xbb created',\n  created: 'Account created | Accounts created',\n}\n

我的提交方法

submit() \n   this.$notifications.add({\n        type: 'success',\n        html: accounts.length === 1\n        ? this.$tc('AccountNotifications.created', 1)\n        : this.$tc('AccountNotifications.created', 2),\n  });\n

我的输出

app.js:290949 TypeError: this.$tc is not a function\n

怎么了？
