[在Python虚拟环境处于活动状态时启动NeoVim时发生NameError

Question

当激活virtualenv时启动NeoVim时，出现以下错误：

Error detected while processing function provider#python3#Call:
line   18:
Error invoking 'python_execute' on channel 3 (python3-script-host):
Traceback (most recent call last):
  File "<string>", line 6, in <module>
NameError: name 'execfile' is not defined
Press ENTER or type command to continue

这是我在运行:checkhealth provider时看到的内容：

我不使用Zsh，我使用Bash。尝试使用.bashrc中链接的答案中的代码片段不会更改情况。

在激活virtualenv的情况下不启动NeoVim时没有出现错误。

删除所有Vim插件并没有消除错误。

我已经使用同时使用Python 2和Python 3的virtualenvs进行了尝试。错误相同。

我相信您在init.vim中的第g:python3_host_prog = "~/.virtualenvs/neovim-python3-venv/bin/python3"行之前有一些python代码，并且在您启动nvim时，在知道要使用哪个解释器之前，该代码正在尝试执行。（至少我在战斗半天时遇到了同样的问题）

因此只需将提到的行放在python代码之前。
