Not working with pylsp installed from Snap in Ubuntu 18.04

I'm using ide-python with Atom 1.58.0 and Ubuntu 18.04.
I've installed Python language server from the Snap store, the executable pylsp is correctly addressed from a terminal (e.g. if I do `pylsp -h` or `pylsp -v`).
The version of pylsp should be 1.0.1.

However, when I start Atom I get the error "Unable to start the Python language server" etc.

In the ide-python settings the executable string is the default (`pylsp`).

Am I missing something?
Is it supposed not to be working this way? (I'd prefer not to use pip, to not have to take care of updates).

首先，在 Ubuntu 18.04 上使用 Atom 1.58.0、ide-python 的默认 `pylsp` 可执行文件以及从 Snap 安装的 pylsp 1.0.1 重现该故障。比较 Atom 使用的环境与 `pylsp -h` 可以正常工作的终端环境；当 Python language server 能够从 ide-python 成功启动时，即表示完成。
