我的Python软件包有一个setup.py可以在Ubuntu Trusty上本地构建并在一个新的Vagrant Ubuntu Trusty VM上构建,当我像这样配置它时:

sudo apt-get install python python-dev --force-yes --assume-yes --fix-broken
curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py | sudo python2.7
sudo -H pip install setuptools wheel virtualenv --upgrade

但是当我在Travis CI Trusty Beta VM上做同样的事情时:

- sudo apt-get install python python-dev --force-yes --assume-yes --fix-broken
- curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py | sudo python2.7
- sudo -H pip install setuptools wheel virtualenv --upgrade

我明白了:

python2.7 setup.py bdist_wheel
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help …

我运行"sudo pip install psycopg2",我得到一堆看起来像的输出

cc -DNDEBUG -g -fwrapv -Os .....
.....
cc -DNDEBUG -g -fwrapv -Os .....
.....

最后它说:

ld: library not found for -lssl

clang: error: linker command failed with exit code 1 (use -v to see invocation)

error: command 'cc' failed with exit status 1

我正在为我的一个讲座工作项目,我需要下载包psycopg2才能使用正在使用的postgresql数据库.不幸的是,当我尝试pip安装psycopg2时会弹出以下错误:

ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/bin/clang' failed with exit status 1
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/bin/clang' failed with exit status 1

有谁知道为什么会这样？是因为Sierra没有支持某些套餐吗？提前致谢!

我在 OSX 中安装 psycopg2 时遇到了很大的麻烦。使用自制软件安装 Postgresql 9.5.4_1 后，我尝试在我的虚拟环境中安装 psycopg2： pip install psycopg2

我还使用 pg_config 添加到我的路径中 PATH=$PATH:/usr/local/Cellar/postgresql/9.5.4_1/bin/pg_config

执行后，我收到许多错误，包括：

  ld: library not found for -lssl


 clang: error: linker command failed with exit code 1 (use -v to see invocation)
  error: command 'clang' failed with exit status 1

尝试从源代码构建会导致类似的错误...
