在 Centos7 上从源代码安装 couchbase-python-client

Question

我正在尝试在 Centos7 上安装 couchbase python 包。 libcouchbase 和 Python 客户端似乎都可以毫无问题地构建和安装，但是当我尝试在解释器中导入模块时，我得到：

Python 3.4.3 (default, Oct  6 2015, 15:22:55) 
[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux

>>> import couchbase

  File "/usr/local/lib/python3.4/site-packages/couchbase-2.0.4-py3.4-linux-x86_64.egg/couchbase/_bootstrap.py", line 34, in <module>
    import couchbase.exceptions as E
  File "/usr/local/lib/python3.4/site-packages/couchbase-2.0.4-py3.4-linux-x86_64.egg/couchbase/exceptions.py", line 18, in <module>
    import couchbase._libcouchbase as C
ImportError: libcouchbase.so.2: cannot open shared object file: No such file or directory

我正在构建 libcouchbase：

cd /
git clone git://github.com/couchbase/libcouchbase.git
cd libcouchbase
mkdir build
/libcouchbase/cmake/configure
make && make install

构建python包：

cd /usr/local/lib/python3.4/site-packages
git clone git://github.com/couchbase/couchbase-python-client
cd couchbase-python-client
python3.4 setup.py build_ext --inplace --library-dir /usr/local/lib --include-dir /usr/local/include/libcouchbase
python3.4 setup.py install

我也试过不带标志的setup.py build。

Python 路径：

/usr/local/lib/python3.4/site-packages/couchbase-2.0.4-py3.4-linux-x86_64.egg
/usr/local/lib/python34.zip
/usr/local/lib/python3.4
/usr/local/lib/python3.4/plat-linux
/usr/local/lib/python3.4/lib-dynload
/usr/local/lib/python3.4/site-packages

$PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

您应该将/usr/local/lib 添加到LD_LIBRARY_PATH。

在 shell 中运行命令：

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
