在 Ubuntu 18.04 上重新安装 pip3

Question

最近我遇到了在 Ubuntu 18.04 上pip3无法正常工作的问题：

:~$ pip3 install jinja2
Traceback (most recent call last):
  File "/home/redra/.local/bin/pip3", line 7, in <module>
    from pip import main
ModuleNotFoundError: No module named 'pip'

然后我尝试重新安装 pip3，似乎是由于它并面临另一个问题：

:~$ sudo -H python3 get-pip.py
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting pip
  Retrying (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/pip/
  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/pip/
  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/pip/
  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/pip/
  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/pip/

我猜它卡住了......由于pip3不好，我无法安装openssl，并且由于openssl无法安装新的pip3......似乎是循环（

有什么建议吗？有没有人遇到过同样的问题？

Answer 1

这可能是因为openssl编译 python 时所需的二进制文件不存在，以解决此问题

• 从以下位置下载 openssl（tar.gz 可以解决问题）：https : //www.openssl.org/source/

• 在文件夹中解压 SSL 源

• 转到文件夹并运行以下命令来制作 openssl

  ./configure && make && sudo make install

最后 - 重做 Python 编译（configure、make、make install），观察 ssl 库现在编译成 Python，因为它出现在 Python 编译过程正在寻找的标准位置。
