1.安裝python3.7以及pip3

1)首先來安裝依賴

yum -y install gcc gcc-c++ yum -y groupinstall “Development tools” yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel libffi-devel

2)然后下載 Python-3.7.0 的源碼并解壓：

mkdir -p ~/src cd ~/src wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz tar -zxvf Python-3.7.0.tgz

3)編譯安裝：

cd Python-3.7.0 ./configure –prefix=/usr/local/python3 make && make install

4)最后創建軟鏈接

ln -s /usr/local/python3/bin/python3 /usr/bin/python3 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

5)測試

python3 --version pip3 --version

升級pip3命令：

pip3 install –upgrade pip

2.使用pip3安裝pipenv時pip報錯

安裝指令：

pip3 install pipenv

錯誤信息：

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. Collecting virtualenvRetrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/virtualenv/Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/virtualenv/Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/virtualenv/Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/virtualenv/Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/virtualenv/Could not fetch URL https://pypi.org/simple/virtualenv/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/virtualenv/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skippingCould not find a version that satisfies the requirement virtualenv (from versions: ) No matching distribution found for virtualenv pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

原因：
yum 安裝的openssl 版本都比較低，即pip依賴出現問題，導致pip未夠正常使用，需要更新依賴！

解決方案：
戳這里 謝謝作者分享！

3.使用pip3安裝pipenv時出現ReadTimeoutError

安裝指令：

pip3 install pipenv

錯誤信息（此時簡略錯誤信息）：

ReadTimeoutError

解決方案：
使用以下指令：

pip3 --default-timeout=100 install pipenv

4.查看pipenv版本報錯

[root@instance-6lf3j8lp Python-3.7.0]# pipenv --version -bash: pipenv: command not found

原因：未建立軟鏈接
解決方案：

ln -s /usr/local/python3/bin/pipenv /usr/bin/pipenv
