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

python文档实际上非常清楚,按照说明做了工作,而我在这里找到的其他答案并没有解决这个问题。

首先,安装python 3.x。例如3.6.2版本https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz 通过运行brew install openssl,确保已经安装了openssl tar xvzf python -3.6.2.tar。xz && cd Python-3.6.2 然后如果python版本< 3.7,则运行

CPPFLAGS="-I$(brew -prefix openssl)/include" \ LDFLAGS="-L$(brew -prefix openssl)/lib" \ . / configure——with-pydebug 5. 最后,运行make -s -j2 (-s是沉默标志,-j2告诉您的机器使用2个作业)

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.

我可以通过更新这个文件中的python版本来修复这个问题。 pyenv: version ' 3.6.5'未安装(由/Users/taruntarun/.python-version设置) 虽然我安装了最新版本,但我的命令仍然使用旧版本3.6.5

转到3.7.3版本

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

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。

在Ubuntu中,这可以帮助:

cd Python-3.6.2
./configure --with-ssl
make
sudo make install
