Problem Description
When in the Ubuntu environment, manually install Python3.7 and above, error missing dependencies (lack _ctype) will appear in the make install step.
The reason given
So, in python3.X used in the _ctype assembly, but he must rely on another component libffi-devel called, so we need to be installed first.
Solution
First is different from the environment, divided into two cases.
Centos7
#执行以下命令
yum install libffi-devel
Ubuntu
sudo apt-get install libffi-dev
When the commands above but prompt
Reading package lists ... Done
Building dependency tree package
Reading state information ... Done
E: Unable to locate package libffi-devel
Therefore the following command to install dependent components:
sudo apt-get update
sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus
sudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-dev
sudo apt-get install zlib1g-dev libsqlite3-dev tk-dev
sudo apt-get install libssl-dev openssl
sudo apt-get install libffi-dev
sudo apt-get install libxpm-dev libxext-dev
sudo apt-get install zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev
Then you can compile and install it again
