用Anacond安装本地包

Question

我使用的是64位Python2.7的Anaconda，它在Windows7机器上必须与internet隔离。我在安装本地软件包时遇到困难。现在我被PyMySQL困住了，但我想其他包也会有同样的问题。我的系统路径变量在开头有Anaconda。

正在尝试解压缩文件夹的路径：

conda install –-offline c:\temp\PyMySQL-master\pymysql
PackageNotFoundError: Package missing in current win-64 channels:
  - c:\temp\pymysql-master\pymysql

这个错误是什么意思？我试过使用tar文件，得到了同样的错误消息。这和我拼写错误的文件名得到的消息是一样的，所以我缺少了一些东西来让它识别文件。我需要为本地包创建频道吗？我该怎么做？还有什么我该试试的吗？

以下是详细模式下的响应：

conda install --offline --verbose c:\temp\pymysql.tar

迄今为止构建的每一个conda包都有一个.tar.bz2扩展名，这一假设已经根深蒂固。总有一天，我们可能会添加不同的包类型、压缩算法和扩展，但这还远远不够。所以为了工作，你的命令必须是

conda install --offline --verbose c:\temp\pymysql.tar.bz2

而且pymysql.tar.bz2需要是一个真正的conda包。（也就是说，如果您打开tarball，并且其中没有info/files文件，那么它就不是conda包）
