I want to install Anaconda and do machine learning using Tensorflow, but I can't install it because I get an error saying Permission denied.

Prerequisites/What you want to achieve

I want to study the machine learning model of image recognition, so I want to install Anaconda and study in my own way using Tensorflow and Keras.
Therefore, we installed Anaconda 5.1 for the Python 3.6 version mac and ran it from the command prompt.I am a beginner in programming including machine learning and environmental construction, and I have no development experience.

Problems/Error Messages you are experiencing

On my PC, I often get a "permission denied" error message during decompression and installation, and I often don't accept commands.

You will not be able to install Tensorflow anyway with permission denied as shown in .

Tried

Based on the error message, I tried the following methods by referring to various commentary sites, but all of them failed.
·Execute code by adding sudo or --user or setting umask loosely→ Same error
·Delete all folders/files related to python and reinstall anaconda→ Same error
·Try to install tensorflow using anaconda navigator → After loading, nothing is added (permission denied is probably happening behind the scenes)
·(env)(tonsorflow)$ Enter the tensorflow virtual environment and do the same thing→ Same error

Supplementary information (for example, FW/Tool Version)

Current Conditions:
·Macbook Pro 10.12.6 (high quality used item)
·echo$PATH
/anaconda3/bin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin
·.bash_profile
export PATH="/anaconda3/bin:$PATH"
·Python 2.7.15
·The same file as /Users/keisuke and /Users/keisuke/Downloads/code contains anaconda3 (the contents are different).
