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

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。

其他回答

好的,这个问题的最新答案是,到目前为止不要使用Python 3.8,只使用3.7或更少的版本,因为大多数库都无法安装上面的错误

我也遇到了同样的问题,并能够通过以下步骤解决:

sudo yum install -y libffi-devel
sudo yum install openssl-devel
cd /usr/src
sudo wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz
sudo tar xf Python-3.7.1.tar.xz
cd Python-3.7.1
sudo ./configure --enable-optimizations
# Install into /usr/local/bin/python3.7, don't overwrite global python bin
sudo make altinstall

根据烫发的不同,你可能不需要sudo。

Results:
Collecting setuptools
Collecting pip
Installing collected packages: setuptools, pip
Successfully installed pip-10.0.1 setuptools-39.0.1

现在应该可以运行了吗

python3.7 -V 

and

pip3.7 -V

安装包时:

pip3.7 install pandas

或者根据烫发,你也可以像这样添加——user标志:

pip3.7 install pandas --user

降级openssl对我有用,

brew switch openssl 1.0.2s

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.

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
