尝试在conda中脱机安装程序包时出现错误消息

Question

我有一台笔记本电脑无法连接到互联网，我有一个工作版本的Anaconda 3版本4.2。我还想安装PyVISA package。

我下载了tar.bz2文件并将其复制到Anaconda3 / pkgs文件夹中。我导航到该目录并使用命令：

C:\Program Files\Anaconda3\pkgs>conda install --offline --use-local --use-index-cache pyvisa-1.8-py35_0.tar.bz2

我得到的回应是：

Extracting packages ...
An unexpected error has occurred.                                     |   0%

从“列表索引超出范围”我发现它可能找不到文件，所以我使用了完整路径：

这里发生了什么？有没有办法离线安装此软件包？

更新1：

按照以下建议我试过

C:\Program Files\Anaconda3\pkgs>conda install --offline --use-local --use-index-cache --debug "C:\Program Files\Anaconda3\pkgs\pyvisa-1.8-py35_0.tar.bz2"

现在我得到了：

CondaValueError: Value error: invalid package specification

作为默认错误消息，如果我使用debug，则为以下内容：

DEBUG conda.models.channel:__init__(140): making channel object for url:https://repo.continuum.io/pkgs/free/win-32/alabaster-0.7.9-py35_0.tar.bz2

等等，看起来像我的所有包裹，然后是

Answer 1

替换......

conda install --offline --use-local --use-index-cache C:\Program%20Files\Anaconda3\pkgs\pyvisa-1.8-py35_0.tar.bz2

... with：

conda install --offline --use-local --use-index-cache "C:\Program Files\Anaconda3\pkgs\pyvisa-1.8-py35_0.tar.bz2"

基本上，不要对绝对路径进行URI编码。
