anaconda在linux下的安裝注意事項

不該該作什麼

官網原文：

Installation Instructions

Linux Install

These instructions explain how to install Anaconda on a Linux system.

After downloading the Anaconda installer, run the following command from a terminal:

bash Anaconda-2.x.x-Linux-x86[_64].sh

After accepting the license terms, you will be asked to specify the install location (which defaults to ~/anaconda).

Note: You do NOT need root privileges to install Anaconda, if you select a user writable install location, such as ~/anaconda.* After the self extraction is finished, you should add the anaconda binary directory to your PATH environment variable.

As all of Anaconda is contained in a single directory, uninstalling Anaconda is easy (you simply remove the entire install location directory).

雖然原文裏寫You do NOT need root privileges to install Anaconda，其實根本不該該使用root權限（或者sudo）。

若是使用sudo ./Anaconda-2.x.x-Linux-x86[_64].sh的方式安裝，則用戶失去了anaconda文件夾的寫入權限，只剩下執行權限，這樣會致使使用pip或者conda安裝軟件時沒法寫入軟件包！！！

安裝程序作了什麼

若是是以默認路徑安裝anaconda，安裝程序會在安裝過程當中修改～/.bashrc文件，加上了下面一行命令：

export PATH="/home/ric/anaconda/bin:$PATH"
