如何在 Amazon1 EC2 实例 (Cloud9) 上安装/配置 python 3.7？

Question

I am using AWS Cloud9 Amazon1 (EC2) instance.

Python 2.7 is pre-installed.

I am not sure where the python 3.7 is to be installed - home dir or root dir? Can someone help me with the steps to install python 3.7 such that it meets the following criteria:

If Python 3.7 is installed on the device, name the binary 'python3.7' and add its parent directory to the PATH environment variable.

Note that apt-get is not supported. yum works.

Update :

I have followed the steps from answer and installed python 3.7 successfully and checked by firing python3.7 -V . However, the dependency checker is unable to detect the python 3.7:

mkdir greengrass-dependency-checker-GGCv1.11.x
cd greengrass-dependency-checker-GGCv1.11.x
wget https://github.com/aws-samples/aws-greengrass-samples/raw/master/greengrass-dependency-checker-GGCv1.11.x.zip
unzip greengrass-dependency-checker-GGCv1.11.x.zip
cd greengrass-dependency-checker-GGCv1.11.x
sudo ./check_ggc_dependencies | more

Answer 1

Based on the comments.

There is no native package for python 3.7 on Amazon Linux 1. Thus, it should be compiled as shown here . The compilation steps include:

1. Installation of dependencies,

yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel

2. Downloading python source:

cd /usr/src
wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz

3. Extract Python-3.7.9

tar xzf Python-3.7.9.tgz

4. Compilation

cd Python-3.7.9
./configure --enable-optimizations
make altinstall

5. Cleanup

rm /usr/src/Python-3.7.9.tgz

Update

Need to sym link pyhton:

ln -s /usr/local/bin/python3.7 /usr/bin/python3.7

Answer 2

You will most likely have to either:

• Compile it from source
• Use pyenv that will compile it too

Answer 3

If you're creating the Cloud9 environment from the console (web browser instead of CloudFormation) then you can now use Amazon Linux 2. That should have a more up to date set of tools installed.
