感谢CSDN
ZeroZone零域 的文章：
Anaconda找包，安装包时，遇到PackageNotFoundError： ”Package missing in current channels”

以及 CSDN
神马呵呵哒 的文章
如何给Python安装.whl文件 – weixin_41592575的博客 – CSDN博客

在import talib时，系统报错

No module named 'talib'

需要安装 talib 包，但是如果直接在 anaconda promt里面打：

$ conda install talib

系统会报：

PackageNotFoundError: Packages missing in current channels:

这个时候，需要首先查一下anaconda可以安装的包都有哪些：

$ anaconda search -t conda TA-Lib
Using Anaconda API: https://api.anaconda.org
Packages:

Found 12 packages

Run 'anaconda show <USER/PACKAGE>' to get installation details

我们可以选择某个包，查看具体的信息：

$ anaconda show Quantopian/ta-lib

Using Anaconda API: https://api.anaconda.org
Name:    ta-lib
Summary:
Access:  public
Package Types:  conda
Versions:
   + 0.4.8
   + 0.4.9

To install this package with conda run:
     conda install --channel https://conda.anaconda.org/Quantopian ta-lib

复制最后一句，粘贴后运行：

$ conda install --channel https://conda.anaconda.org/Quantopian ta-lib

UnsatisfiableError: The following specifications were found to be in conflict:
  - python 3.6*
  - ta-lib -> python 3.4*
Use "conda info <package>" to see the dependencies for each package.

版本不对，那么尝试下载whl安装，下载链接：Python Extension Packages for Windows

我用的python 3.6 下载 TA_Lib-0.4.17-cp36-cp36m-win_amd64.whl后放到D盘anaconda scripts文件夹下，然后prompt里面用cd命令跳到该文件夹下：

(D:\Anaconda3) C:\Users\x>cd D:\Anaconda3\Scripts

(D:\Anaconda3) C:\Users\x>d:

(D:\Anaconda3) D:\Anaconda3\Scripts> pip install TA_Lib-0.4.17-cp36-cp36m-win_amd64.whl
Processing d:\anaconda3\scripts\ta_lib-0.4.17-cp36-cp36m-win_amd64.whl
Installing collected packages: TA-Lib
Successfully installed TA-Lib-0.4.17

显示已安装成功
