无法安装kivy？

• 问答

我正在尝试将kivy下载到cmd和anaconda。在Anaconda中，我写了conda install kivy -c conda-forge，但显示的错误是

Collecting package metadata (current_repodata.json): done
Solving environment: failed with current_repodata.json,will retry with next repodata source.

然后我尝试python -m pip install kivy在cmd上下载，并且发生了此错误

对我来说解决了这个问题

,

使用pip安装时出现的错误消息显示缺少的内容：

...

SystemExit: error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

需要MVC ++库。

我建议先安装wheel，然后再继续进行kivy，并遵循官方 Kivy installation guide。 

python -m pip install --upgrade pip wheel setuptools virtualenv
,

我也遇到了这个问题，按照@farzad的说明安装MVC ++ 14之后，出现了另一个错误。 下一个错误已解决by this，该错误说应从其内部版本而不是pypi进行安装。

在上面的链接中检查错误，如果遇到错误，请运行以下命令：

require 'active_record/connection_adapters/postgresql_adapter'

class ActiveRecord::ConnectionAdapters::PostgreSQLAdapter
  def set_standard_conforming_strings
    old,self.client_min_messages = client_min_messages,'warning'
    execute('SET standard_conforming_strings = on','SCHEMA') rescue nil
  ensure
    self.client_min_messages = old
  end
end
