vim -您让我无法找到合适的Python库。
我遵循了这里的说明，https://github.com/Valloric/YouCompleteMe并安装了这两种设备：
Cmake sudo apt-get install build-essential cmake
和Python sudo apt-get install python-dev python3-dev
然后我cd ~/.vim/bundle/YouCompleteMe和运行：./install.py --clang-completer，我得到：
Searching Python 2.7 libraries... ERROR: unable to find an appropriate Python library.
然后我尝试了python3 install.py --clang-completer，但仍然得到：
Searching Python 3.4 libraries... ERROR: unable to find an appropriate Python library.
有人知道发生了什么事吗？谢谢

脚本没有找到通向python库的路径。在执行以下操作之前，您可能需要确保安装了setuptools：
您所看到的错误可能是由~/.vim/bundle/YouCompleteMe/third_party/ycmd/build.py中第149行的函数FindPythonLibrariesOnLinux()返回的
您可以通过创建一个名为youcompletemetest.py的文件来运行脚本中导致问题的部分，并用以下代码填充它：
import sys
import os.path as p
import subprocess
import re
NO_PYTHON_LIBRARY_ERROR = 'ERROR: unable to find an appropriate Python library.'
PY_MAJOR, PY_MINOR = sys.version_info[ 0 : 2 ]
LIBRARY_LDCONFIG_REGEX = re.compile(
'(?P<library>\S+) \(.*\) => (?P<path>\S+)' )
if not ( ( PY_MAJOR == 2 and PY_MINOR >= 6 ) or
( PY_MAJOR == 3 and PY_MINOR >= 3 ) or
PY_MAJOR > 3 ):
sys.exit( 'ycmd requires Python >= 2.6 or >= 3.3; '
'your version of Python is ' + sys.version )
def GetPythonNameOnUnix():
python_name = 'python' + str( PY_MAJOR ) + '.' + str( PY_MINOR )
# Python 3 has an 'm' suffix on Unix platforms, for instance libpython3.3m.so.
if PY_MAJOR == 3:
python_name += 'm'
return python_name
def GetStandardPythonLocationsOnUnix( prefix, name ):
return ( '{0}/lib/lib{1}'.format( prefix, name ),
'{0}/include/{1}'.format( prefix, name ) )
def CheckOutput( *popen_args, **kwargs ):
process = subprocess.Popen( stdout=subprocess.PIPE, *popen_args, **kwargs )
output, unused_err = process.communicate()
retcode = process.poll()
if retcode:
command = kwargs.get( 'args' )
if command is None:
command = popen_args[ 0 ]
error = subprocess.CalledProcessError( retcode, command )
error.output = output
raise error
return output
def FindPythonLibrariesOnLinux():
python_name = GetPythonNameOnUnix()
python_library_root, python_include = GetStandardPythonLocationsOnUnix(
sys.exec_prefix, python_name )
python_library = python_library_root + '.so'
if p.isfile( python_library ):
return python_library, python_include
python_library = python_library_root + '.a'
if p.isfile( python_library ):
sys.exit( NO_DYNAMIC_PYTHON_ERROR.format( library = python_library,
flag = '--enable-shared' ) )
# On some distributions (Ubuntu for instance), the Python system library is
# not installed in its default path: /usr/lib. We use the ldconfig tool to
# find it.
python_library = 'lib' + python_name + '.so'
ldconfig_output = CheckOutput( [ 'ldconfig', '-p' ] ).strip().decode( 'utf8' )
for line in ldconfig_output.splitlines():
match = LIBRARY_LDCONFIG_REGEX.search( line )
if match and match.group( 'library' ) == python_library:
return match.group( 'path' ), python_include
sys.exit( NO_PYTHON_LIBRARY_ERROR )
print "\n".join(FindPythonLibrariesOnLinux());您可以使用以下方法运行该文件：
python youcompletemetest.py 对我来说，这将产生
/usr/lib/x86_64-linux-gnu/libpython2.7.so /usr/include/python2.7
但对你来说却找不到巨蟒。如果您知道python的安装位置，就可以找到该路径，并将名为FindPythonLibrariesOnLinux()的函数的全部内容替换为包含python库位置的数组。
所以打开源文件：
vi ~/.vim/bundle/YouCompleteMe/third_party/ycmd/build.py查找不起作用的函数: /^def\sFindPythonLibrariesOnLinux
更改该函数，以便它只返回python库的完整路径(在我的示例中如下所示)：
def FindPythonLibrariesOnLinux():
return ["/usr/lib/x86_64-linux-gnu/libpython2.7.so","/usr/include/python2.7"]现在，您将能够继续安装：

在为python3.4安装python软件包之后，可以在libpython3.4.dll.a.上使用cygwin上的YouCompleteMe (*.a)版本。
所以我修改了：
~/.vim/bundle/YouCompleteMe/third_party/ycmd/build.py通过以下方式：
def FindPythonLibrariesOnLinux():
return ["/usr/lib/libpython3.4.dll.a","/usr/include/python3.4"]我正在使用：(Cygwin_NT-10.02.7.0(0.306/5/3) 2017-02-12 13:18 x86_64 Cygwin)
