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

其他回答

我在ubuntu14.04机器上安装python3.7时遇到了同样的问题。 问题是我的PKG_CONFIG_PATH和LD_LIBRARY_PATH中有一些自定义文件夹,这阻止了python构建过程找到系统openssl库。

所以试着清除它们,看看会发生什么:

export PKG_CONFIG_PATH=""
export LD_LIBRARY_PATH=""

前两天我也遇到了同样的问题,直到现在才解决。

我尝试使用digicert_high_asance_ev_root_ca的——trust-host选项。pem不工作,我无法安装ssl模块(它告诉它不能安装python版本大于2.6),设置$PIP_CERT变量也没有修复它,我安装了libssl1.0.2和libssl1.0.0。值得一提的是,我没有~/.pip/pip.conf文件,创建它也没有解决这个错误。

最终解决这个问题的方法是再次使用make安装python3.6。 下载Python-3.6.0。从网站TGZ,运行配置,然后使,使测试,使安装。希望这对你有用。

I finally solve this issue. These are the detail of my env: Version of Python to install: 3.6.8 OS: Ubuntu 16.04.6 LTS Root access: No Some people suggest to install libssl-dev, but it did not work for me. I follow this link and I fixed it! In short, I download, extract, build, and install OpenSSL (openssl-1.1.1b.tar.gz). Then, I modify .bashrc file follow this link. Next, I download and extract Python-3.6.8.tgz. I edit Modules/Setup.dist to modify SSL path (lines around #211). I did ./configure --prefix=$HOME/opt/python-3.6.8, make and make install. Last, I modify my .bashrc. Notice that I do not include --enable-optimizations in ./configure.

在我使用Mac的情况下,我删除了 /应用程序/ Python 3.7。 因为我已经通过brew安装了Python3.7。

但这是信息的一个触发点

pip配置了需要TLS/SSL的位置,但是Python中的SSL模块不可用。

我在这种情况下做了什么

我再次下载了macOS 64位安装程序,并安装。 双击/Applications/Python3.6/Install Certificates.command和/Applications/Python3.6/Update Shell Profile.command。 重启mac 我不确定,但可能有助于成功的是pip.conf。参见pip安装失败。

如果在窗户和使用蟒蛇,比我先解决它,

conda activate
pip install <lib>

这对我很管用。
