[kiennq]

Correct the usage of encode-time, will make the download of python-language-server-ms success.
The currently used syntax is only available in Emacs 27

@seagle0128 can you take a look?

[seagle0128]

I am fine with the change. I noticed @Isolet reported #39.

@Isolet, can you please test it?

@seagle0128 @yyoncho According to my test in both Emacs26 & 27, this PR solves #39.

[seagle0128]

Still can't get it work

Command "/Users/isol/.emacs.d/savefile/var/lsp-python-ms/Microsoft.Python.LanguageServer" is not present on the path. Command "pyls" is present on the path. Found the following clients for /Users/isol/Git/tags.py: (server-id pyls, priority -1) The following clients were selected based on priority: (server-id pyls, priority -1) 

But the executable is in fact there.

The extracted server has no executable flag.

I wonder if it's only the issue of my OS.

@Isolet Did you set lsp-python-ms-dir or lsp-python-ms-executable?
"/Users/isol/.emacs.d/savefile/var/lsp-python-ms/Microsoft.Python.LanguageServer" is not the default path. lsp-python-ms-dir and lsp-python-ms-executable shoud be matched. If the path is invalid, the chmod may not be executed correctly. You can try to run chmod +x manually.

I only set lsp-python-ms-dir. lsp-python-ms-dir and lsp-python-ms-executable do match. I have to chmod +x manually.

@Isolet I set lsp-python-dir to ~/.emacs.d/var/lsp-python-ms/ and did test with Emacs 27 on macOS. It does work well. Please update to the latest version and retry.
