【问题描述】：
嘿 StackOverflowers！
我遇到了问题。
我已将 PyCharm 设置为通过 SSH 连接与（天蓝色）VM 连接。
-
我设置了映射
-
我通过在 vm 中启动一个终端来创建一个 conda 环境，然后我下载并连接到 databricks-connect。我在终端上测试它，它工作正常。
但是当我尝试运行 spark 会话 (spark = SparkSession.builder.getOrCreate()) 时，databricks-connect 在错误的文件夹中搜索 .databricks-connect 文件并给我以下错误：
Caused by: java.lang.RuntimeException: Config file /root/.databricks-connect not found. Please run databricks-connect configure to accept the end user license agreement and configure Databricks Connect. A copy of the EULA is provided below: Copyright (2018) Databricks, Inc.
以及完整的错误 + 一些警告。

但是，我没有对该文件夹的访问权限，因此我无法将 databricks 连接文件放在那里。
还有什么奇怪的是，如果我运行在：Pycharm -> ssh terminal -> activate conda env -> python 以下
这是一种方法吗：
1. Point out to java where the databricks-connect file is
2. Configure databricks-connect in another way throughout the script or enviromental variables inside pycharm
3. Other way?
or do I miss something?

我猜它在
/root/目录中查找，因为您以 root 身份运行。您是否尝试过以普通用户身份运行该命令？它看起来在同一个目录中吗？你能在虚拟环境中安装databricks-connect吗？
