STAMP是一款非常好用的宏基因组分析相关软件。最近想在mac上面安装，差点被搞疯了，还好最后解决了。这里有个网站和视频对其安装进行了说明：
http://microcell.ufl.edu/mcs-apps/videos/instructional-videos/stamp-mac.html
其步骤如下：
1) Open a terminal window and Install Xcode command line tools. In the window that will pop up, select 'install'

xcode-select  --install

2) Install Anaconda Package for Python 2.7 (Be sure to install the version for Python 2.7) from: https://www.anaconda.com/download/#macos. After installation CLOSE THE TERMINAL and open it again to check that anaconda is installed by typing:

anaconda --version

3) In Terminal, type the following command to create the STAMP script:

conda create -y -n stamp-test python=2.7

4) Type this to activate the script:

source activate stamp-test

5) Type this to install STAMP:

conda install -y -c bioconda stamp

6) Type this to open STAMP:

STAMP

STAMP is now installed.

*****Every time you want to use STAMP you must activate the script in Terminal using:**

source activate stamp-test

**and then:*****

STAMP

虽然按照其步骤进行安装，到了第5步的时候，我仍然收到了一下报错：

UnsatisfiableError: 

疯狂报错，快要窒息。后面到处查文档，发现主要是conda版本太高造成地，需要降级，更正后步骤如下：
1）降级conda

conda install -n root conda=4.6

2）

conda create -n stamp
conda activate stamp

conda install -y -c bioconda stamp

然后打开STAMP

注意：

每次使用，打开方式为

conda activate stamp
STAMP

完美解决问题

如果报错Unknown Parsing Error" dialog，可能是因为导入的路径含有中文字符
