当使用pip3安装包时，“Python中的ssl模块不可用”

我已经在我的本地机器上成功安装了Python 3.4和Python 3.6，但无法安装带有pip3的包。

当我执行pip3 install <package>时，我得到以下SSL相关错误:

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting <package>
  Could not fetch URL https://pypi.python.org/simple/<package>/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping
  Could not find a version that satisfies the requirement <package> (from versions: )
No matching distribution found for <package>

如何修复我的Python3。pip install <package>?

当前回答

从源代码构建是我在Ubuntu 22.10上的工作方式:

手动安装OpenSSL，在这里用OpenSSL 1.1.1测试，提取然后运行:

./config --prefix='/opt/openssl' --openssldir='/opt/ssl'
make
make install

然后使用旧版本的Python 3(这里是Python-3.8.16)运行:

export LD_RUN_PATH='/opt/openssl/lib'
export CC='gcc-12'  # sudo apt install gcc-12
./configure --enable-optimizations \
            --with-openssl='/opt/openssl' \
            --prefix='/opt/python/3.8' -C
make
make install

测试:

/opt/python/3.8/bin/python3 -c 'import ssl; print(ssl.OPENSSL_VERSION)'
OpenSSL 1.1.1s  1 Nov 2022

在Ubuntu中安装Python 3.6和pip3的分步指南

安装Python和ssl所需的包:$ sudo apt-get Install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev 下载并解压“Python-3.6.8.tar. zip”。Xz”从https://www.python.org/ftp/python/到您的主目录。打开该目录下的终端，执行:$ ./configure 编译和安装:$ make && sudo make install 使用$ pip3 Install package_name安装包

声明:以上命令未在Ubuntu 20.04 LTS中测试。

如果你使用的是Red Hat/CentOS:

# To allow for building python ssl libs
yum install openssl-devel
# Download the source of *any* python version
cd /usr/src
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
tar xf Python-3.6.2.tar.xz 
cd Python-3.6.2

# Configure the build w/ your installed libraries
./configure

# Install into /usr/local/bin/python3.6, don't overwrite global python bin
make altinstall

如果你在OSX上，万一其他解决方案不适合你(就像我一样)。

您可以尝试卸载python3并升级pip3

brew uninstall --ignore-dependencies python3
pip3 install --upgrade pip

这对我很有用;)

如果你在OSX上并从源代码编译python:

使用brew安装openssl

确保按照brew给出的关于设置CPPFLAGS和LDFLAGS的说明进行操作。在我的情况下，我使用openssl@1.1 brew公式，我需要这3个设置的python构建过程，以正确链接到我的SSL库:

export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

假设库安装在该位置。
