memsql 4.1.7：KeyError：'error_platform'

Question

我一直在尝试运行 memsql 的单节点实例，但被卡住了，不知道如何继续。我在 Google 上没有找到太多信息。

这就是我所做的：

1. 从http://download.memsql.com/memsql-ops-4.1.7/memsql-ops-4.1.7.tar.gz下载最新版本

2. tar xvf memsql-ops-4.1.7.ta​​r.gz

3. memsql-ops-4.1.7.ta​​r.gz/memsql-ops/memsql-ops 开始

我在这一步遇到了这个错误：

 Exception in thread Thread-11:
Traceback (most recent call last):
  File "/usr/local/updated-openssl/lib/python3.4/threading.py", line 921, in _bootstrap_inner
  File "/usr/local/updated-openssl/lib/python3.4/threading.py", line 869, in run
  File "/memsql_platform/memsql_platform/agent/daemon/manage.py", line 198, in startup_watcher

 simplejson.scanner.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

4. 打开了这个 url http://:9000，这是要求添加 memsql 二进制文件，我通过以下命令 $memsql-ops file-add -t memsql memsqlbin_amd64.tar.gz

第 4 步仍然不成功，我无法添加二进制文件。我收到此错误：

simplejson.scanner.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

检查了日志文件，并没有说太多关于错误的信息。

/memsql-ops report throws this error --> KeyError: 'error_platform'

如何进行？

很高兴我们昨天能够在 public slack 上解决这个问题 (http://chat.memsql.com)。对于遇到此问题的其他人，您无法通过解压缩新版本并运行它来升级 MemSQL Ops。您需要使用memsql-ops agent-upgrade (http://docs.memsql.com/latest/ops/cli/AGENT-UPGRADE/) 命令来升级 MemSQL Ops。您可以通过memsql-ops file-add -t memsql_ops /path/to/tar.gz 使用下载的tar.gz，然后运行memsql-ops agent-upgrade。
