脚本未找到您的 python 库的路径。在执行以下操作之前，您可能需要确保已安装 setuptools：
您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 的文件并用以下代码填充它，只运行导致您出现问题的脚本部分：
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());
您可以使用以下命令运行该文件：
python youcompletemetest.py
对我来说会输出
/usr/lib/x86_64-linux-gnu/libpython2.7.so
/usr/include/python2.7
但对你来说，它无法找到 python。如果您知道 python 的安装位置，您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
查找不起作用的功能：
/^def\sFindPythonLibrariesOnLinux
更改该函数，使其仅返回您的 python 库的完整路径（在我的情况下为以下）：
def FindPythonLibrariesOnLinux():
return ["/usr/lib/x86_64-linux-gnu/libpython2.7.so","/usr/include/python2.7"]
现在您可以继续安装了：
./install.py --clang-completer
