Question

我是Python的新手，需要为我正在执行的项目下载一些模块，但是，每当尝试下载pip时，都会出现此错误。此错误是由于防火墙引起的吗？如果是这样，我有什么办法可以安装pip？

U:\>Py get-pip.py

the ssl module in Python is not available.

Answer 1

如果您的操作系统是Windows，则需要安装OpenSSL。

get-pip.py尝试从请求中提取SSL证书，以将pypi.org验证为可信主机。您的python --version安装很有可能不是由于SSL支持而构建的，因为您的操作系统中没有openSSL二进制文件。再三考虑，确保将python二进制文件和lib添加到系统PATH变量中。

一旦安装了OpenSSL，运行py get-pip.py。

为了确保已安装pip，请在命令提示符下运行pip --version。

此外，可以使用pip install命令using a proxy在公司防火墙后面使用pip安装其他模块。

pip install --proxy http://user:password@proxyserver:port <module-name>

Answer 2

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

对于这种问题，最好使用github，复制并粘贴google并检查github问题。
