我尝试开始使用 Lektor CMS 内部，并希望在出色的 Pycharm 调试器下运行它。特别是我想跑步

$ lektor server

我按照步骤

$ git clone https://github.com/lektor/lektor
$ cd lektor
$ virtualenv venv
$ . venv/bin/activate
$ pip install --editable .
$ make build-js
$ make install-git-hooks
$ export LEKTOR_DEV=1
$ lektor quickstart --path example-project
$ lektor --project example-project server

在关于开发的 Github 自述文件中，它们在终端中工作得很好。然后我创建了以下 Pycharm 调试配置：

但是，这会引发以下 RuntimeException：

显然它找不到 npm 来初始化 Web-UI。将参数 'server' 替换为 'build' 时，调试工作正常。是否不可能通过 Pycharm 调试器内部的子进程运行此 Javascript 代码？

还是我做错了什么？任何想法如何解决这一问题？提前 TNX。

编辑：我在其他一些 SO 线程中读到 Pycharm 可能在 virtualenv 之外的系统 Python 解释器下运行子进程？！？这可以解释为什么它会弄乱依赖关系，但是 npm 命令在系统上的任何地方都可用……那为什么找不到呢？
