| I expect that the root cause is missing libffi(-dev[el]) on your system, preventing _ctypes from building, so your quick fix would be to install that and try again. However, not having _ctypes shouldn't cause installation to fail. Donald, is ctypes a hard requirement for pip to install itself? If so, ensurepip as called by `make install` should either gracefully handle a lack of ctypes or be disabled when ctypes is not available. |

| In <https://bugs.python.org/issue32401#msg308926> Chi-Hsuan suggests “configure --without-ensurepip” as a workaround. |

| Hi All, Iam using centos 7. And as mentioned in this thread, though this error came, Iam able to go to python3.7 interpreter fine. However, when i wanted to install pip, I get the same _ctype error as below. So, I think, this needs to be resolved in order to use python3.7 in centos. File "get-pip.py", line 20651, in main() File "get-pip.py", line 197, in main bootstrap(tmpdir=tmpdir) File "get-pip.py", line 82, in bootstrap import pip._internal File "/tmp/tmpu88jadkc/pip.zip/pip/_internal/__init__.py", line 42, in File "/tmp/tmpu88jadkc/pip.zip/pip/_internal/cmdoptions.py", line 16, in File "/tmp/tmpu88jadkc/pip.zip/pip/_internal/index.py", line 24, in File "/tmp/tmpu88jadkc/pip.zip/pip/_internal/download.py", line 38, in File "/tmp/tmpu88jadkc/pip.zip/pip/_internal/utils/glibc.py", line 3, in File "/usr/local/lib/python3.7/ctypes/__init__.py", line 7, in from _ctypes import Union, Structure, Array ModuleNotFoundError: No module named '_ctypes' Looking for advice. |

| As mentioned before, this is due to missing libffi-devel on a Centos 7 system. Verified it as well on one of my systems. Could you try again, but before just do a 'yum install libffi-devel'? Maybe a warning could be added to the install output when it can't find libffi. |

| In case this helps: I noticed this during the build: *** WARNING: renaming "_ssl" since importing it failed: ld.so.1: python: fatal: libssl.so.1.1: open failed: No such file or directory *** WARNING: renaming "_hashlib" since importing it failed: ld.so.1: python: fatal: libssl.so.1.1: open failed: No such file or directory *** WARNING: renaming "_ctypes" since importing it failed: ld.so.1: python: fatal: libffi.so.6: open failed: No such file or directory ... Following modules built successfully but were removed because they could not be imported: _ctypes _hashlib _ssl In my case the reason was that libffi was installed under /opt/local, so the fix was: ./configure LDFLAGS='-L/opt/local/lib -R/opt/local/lib' and rebuild For other users I would recommend to inspect the build output for _ctypes related errors, I am not saying that the cause is the same |

| Ubuntu 16.04 in a very bare naked setup. Similar/same problem profile by message and other lines in the log. Installed libffi6 and libffi-dev => worked. Not sure if both were needed (or interdependent, 2nd to 1st). |
