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;)

其他回答

我尝试了很多方法来解决这个问题,但没有一个解决。我现在用的是Windows 10。

唯一有效的方法是:

卸载蟒蛇 卸载Python(我使用的是3.7.3版本) 再次安装Python(记得勾选自动添加到PATH的选项)

然后我用PIP下载了我需要的所有lib…和工作!

不知道为什么,或者这个问题是否与水蟒有关。

在使用pyenv来管理Mac OS Catalina上的python安装的情况下,我必须先用brew安装openssl,然后运行pyenv install 3.7.8,这似乎是使用homebrew中的openssl来构建python安装(它甚至在安装输出中这样说)。然后pyenv global 3.7.8,我离开了。

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.

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

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
