起因
為了試試 bpytop 進行了如下折騰 (所有操作均在虛擬機內完成)
先上成果圖
PS： 確實 酷！：)
安裝 python3
1.下載安裝包
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz
or
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz --no-check-certificate
2.解壓
tar -xvJf Python-3.7.0.tar.xz
3.編譯安裝
mkdir /usr/local/python3 #創建編譯安裝目錄
cd Python-3.7.0
./configure --prefix=/usr/local/python3 # ./configure --prefix=/usr/local/python3 --with-ssl
make && make install
編譯過程遇到的報錯&解決辦法
zipimport.ZipImportError: can't decompress data; zlib not available
ModuleNotFoundError: No module named '_ctypes'
4.創建軟連接
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3
5.驗證
python3 -V
pip3 -V

后續:
pip3 無法正常使用,報錯如下:
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
[root@controller upload]# pip3 install --upgrade pip

Requirement already up-to-date: pip in /usr/local/python3/lib/python3.7/site-packages (10.0.1)
You are using pip version 10.0.1, however version 21.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
處理：
# 下載 openssl
wget https://files-cdn.cnblogs.com/files/luckjinyan/openssl-1.1.1g.tar.gz
tar -zxvf openssl-1.1.1g.tar.gz
cd openssl-1.1.1g/
# 編譯安裝
./config --prefix=/usr/local/openssl
make && make install
# 備份&替換舊的 openssl
mv /usr/bin/openssl /usr/bin/openssl.old
mv /usr/lib64/openssl /usr/lib64/openssl.old
mv /usr/lib64/libssl.so /usr/lib64/libssl.so.old
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
ln -s /usr/local/openssl/lib/libssl.so /usr/lib64/libssl.so
echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
ldconfig -v // 建立動態鏈接
# 驗證
openssl version
# 重新編譯 python3
cd Python-3.7.0
./configure --prefix=/usr/local/python3 --with-openssl=/usr/local/openssl
make && make install
