Python 无法自动补全

[nehcuh]

RT，MAC 下的Python，用的Pyenv管理环境，环境切换没有问题，但是无法自动补全，知道如何解决么？

[ztlevi]

你用的是lsp-python-ms?如果是lsp-python-ms的话，我就不知道了，我也才刚开始使用。然后在conda环境下也没有任何问题。

如果是lsp-python的话，可能要在pyenv环境下安装pyls，python3 -m pip install --upgrade 'python-language-server[all]' pyls-isort

[nehcuh]

安装过了，自行编译了 Microsoft.Python.Language.Server，无法补全，估计得切换模式才行

[ztlevi]

没太看懂，你现在是系统环境下的python可以补全是吧

[nehcuh]

在其他编辑器，或者直接在 ipython 环境下，都可以补全，但是在 emacs 下无法自动补全

[ztlevi]

你主要看下这边的配置你写对了吗，如果你自己编译了mspyls，这里得改，确保路径什么的都对哈。

最好贴一下自己的配置，不然我也很难帮你看。。。

如果实在不行，那就把def-package! lsp-python-ms这段给删了，用回pyls算了。

记得安装，python3 -m pip install --upgrade 'python-language-server[all]' pyls-isort

说明

电脑配置如下:

 系统版本：  macOS 10.14.5 (18F203)
  内核版本： Darwin 18.6.0
  启动宗卷： Macintosh HD

现在的疑问是，无论是 macOS, 亦或是 Ubuntu19.04，Python 无法补全， c-c++ 同样如此，但是编辑 el 文件又可以

c++需要编译ccls，follow这里，python的话我用的直接是vscode编译过的mspyls。就是用你的vscode安装python plugin然后打开一个python 文件，然后mspyls就编译好了。接下来fd就会找executable，所以你需要再安装下fd, brew install fd。

[nehcuh]

并没有用，ccls已经安装过了，对于 Python，哪怕自行编译 Microsoft.Language.Server 并手动指定 ms-python-lsp 的位置，一样无法自动补全，😌

[nehcuh]

自定义执行路径如下，并不能自动补全，很神奇，为了测试，使用Centaur Emacs的配置，它的补全不会有问题

lsp-python-ms-executable is a variable defined in lsp-python-ms.el.

Value
"/Users/huchen/.vscode/extensions/python-language-server/output/obj/Microsoft.Python.LanguageServer/netcoreapp2.2/osx.10.14-x64/host/Microsoft.Python.LanguageServer"

lsp-python-ms-dir is a variable defined in lsp-python-ms.el.

Value
"/Users/huchen/.vscode/extensions/python-language-server/output/bin/Release/"

[ztlevi]

你是不是vscode的plugin没更新啊，我这边osx的python plugin路径跟你的不太一样。

然后现在安装编译和更新都已经集成到lsp-python-ms里了，你更新下这个plugin，然后M-x吧。

全部重新安装了，今晚突然发现正常了，回想了下过程，可能是因为emacs打开 Python 代码停留时间太长了，结果居然就正常了，不知道原因为何
