centos python3.10.6 报错 No module named _ssl，坑我几个小时

网上的教程很多，但几乎是无效的，大部分是教大家改Modole/Setup文件，大家千万不要这么做，正确的办法如下：有用的话就收藏吧

常见的错误如下：

 File "/usr/lib/python3.4/urllib/request.py", line 1244, in unknown_open
    raise URLError('unknown url type: %s' % type)
**urllib.error.URLError: **


>>> import ssl
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/python3/lib/python3.6/ssl.py", line 101, in 
    import _ssl             # if we can't import it, let the error propagate
**ModuleNotFoundError: No module named '_ssl'**

• 安装依赖包

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel

• 安装wget

yum install wget

• 安装或更新openssl - https://github.com/openssl/openssl/tags

cd /usr/local/src
wget https://github.com/openssl/openssl/archive/refs/tags/OpenSSL_1_1_1q.tar.gz
tar -zxvf openssl-OpenSSL_1_1_1q.tar.gz
cd openssl-OpenSSL_1_1_1q/
./config --prefix=/usr/local/openssl
make && make test && make install
ln -s /usr/local/bin/openssl /usr/bin/openssl
ln -s /usr/local/lib64/libssl.so.1.1 /usr/lib64/
ln -s /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/
openssl version

• 安装python3 - https://www.python.org/downloads/

wget https://www.python.org/ftp/python/3.10.6/Python-3.10.6.tgz
tar -zxvf Python-3.10.6.tgz
cd Python-3.10.6/
./configure -C --with-openssl=/usr/local/openssl-1.1.1q --with-openssl-rpath=auto --prefix=/usr/local/python3
make -j8
make altinstall
ln -s /usr/local/python3/bin/python3.10 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.10 /usr/bin/pip3
python3 -V

• 验证ssl及_ssl是否安装成功
