最近用到 jieba ，在anaconda 怎么也安装补上，在网上找了一下，发现有几篇文章写得很好，但是为了怕自己以后再浪费时间，这里还是做个记录。
通常安装模块直接用pip install jieba，或者conda install jieba，但是有一些模块是无法使用以上两种方式安装上，这时就需要首先寻找模块，再安装。
1、anaconda search -t conda jieba寻找模块，这时会出现该模块的很多版本的信息如下。
~ » anaconda search -t conda jieba unicorn@unicorndeMacBook-Pro Using Anaconda API: https://api.anaconda.org Packages: Name | Version | Package Types | Platforms | Builds ------------------------- | ------ | --------------- | --------------- | ---------- auto/jieba | 0.32 | conda | linux-64, linux-32 | py27_0 : http://github.com/fxsjy conda-forge/jieba | 0.39 | conda | linux-64, win-32, osx-64, noarch, win-64 | py_1, py36_0, py35_0, py27_0 : Chinese Words Segementation Utilities conda-forge/jieba3k | 0.35.1 | conda | linux-64, win-32, osx-64, win-64, noarch | py36_1001, py37_1001, py36_1, py_0, py35_1001, py35_1 : Chinese Words Segementation Utilities creditx/jieba | 0.38 | conda | linux-64 | py35_0, py27_0 hargup/jieba | | conda | linux-64 | py27_0 : Chinese Words Segementation Utilities iilab/jieba | 0.36.2 | conda | linux-64, osx-64 | py34_0 : Chinese Words Segementation Utilities iilab/jieba3k | 0.35.1 | conda | linux-64, osx-64 | py34_0 : Chinese Words Segementation Utilities jiangxiluning/jieba | 0.36.2 | conda | linux-64, osx-64, win-64 | py27_0 : Chinese Words Segementation Utilities moustik/jieba | 0.38 | conda | linux-64 | py27_0 r/r-jiebard | 0.1 | conda | noarch | r36h6115d3f_0 : jiebaR is a package for Chinese text segmentation, keyword extraction and speech tagging.

2、找到合适的版本，根据版本的信息，输入anaconda show conda-forge/jieba3k，这时会出现该版本的信息如下，再执行最后一行的信息即可安装这时会出现。

3、执行最后一行的信息即可安装输入conda install --channel https://conda.anaconda.org/conda-forge jieba3k 进行安装

这样就安装好了，在anaconda 当前环境中就能看到jieba，打开jupyter notebook import jieba ，可以成功执行。
如果上面方法不行，那只能手动安装了，安装方法如下：
1、从官网下载jieba压缩包
https://pypi.org/project/jieba/#files 下载包
2、将压缩包解压到anaconda的pkgs目录。
3、打开anaconda prompt,切换目录至比如我的D:/anaconda/pkgs/jieba-0.39
然后执行python setup.py install即可。
4、再次打开jupyter notebook 测试import jieba，正常
pycharm中 import jieba ，正常。
