[TOC] ### Linux/MacOs下安裝 **** Dockerfile ``` FROM centos:7 RUN yum -y install zlib-devel \ bzip2-devel \ ncurses-devel \ sqlite-devel \ readline-devel \ tk-devel \ gdbm-devel \ db4-devel \ libpcap-devel \ xz-devel \ libffi-devel \ openssh-server \ perl-DB_File.x86_64 RUN yum install -y wget \ net-tools \ gcc \ gcc-c++ \ make \ cmake WORKDIR /data/ RUN wget https://www.openssl.org/source/openssl-1.1.1a.tar.gz \ && tar -zxvf openssl-1.1.1a.tar.gz \ && cd openssl-1.1.1a \ && ./config --prefix=/usr/local/openssl no-zlib \ && ln -s /usr/local/openssl/include/openssl /usr/include/openssl \ && ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/local/lib64/libssl.so \ && ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl \ && echo "/usr/local/openssl/lib" >> /etc/ld.so.conf \ && ldconfig -v WORKDIR /data/ RUN wget http://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz \ && tar -xvf Python-3.7.1.tar.xz && cd Python-3.7.1/ \ && ./configure --prefix=/usr/local/python37 --with-openssl=/usr/local/openssl --enable-optimizations\ && make && make install RUN mv /usr/bin/python /usr/bin/python_bak \ && ln -s /usr/local/python37/bin/python3.7 /usr/bin/python && ln -s /usr/local/python37/bin/pip3.7 /usr/bin/pip WORKDIR /data/ ``` 執行命令: ``` $ docker build -t python3.7:v0 . ``` ### Windows下安裝 **** 因為我的電腦中以前裝有python，這次重新從網上安裝python3后與之前殘留的設置產生了沖突，打開cmd輸入python出現錯誤： ``` Fatal Python error: Py_Initialize: unable to load the file system codec ModuleNotFoundError: No module named 'encodings'? 原因是以前的環境變量在系統中有殘留導致系統無法識別新安裝的python。 ``` 解決方法： 打開環境變量，在系統變量中的Path中加入兩條環境變量： ``` C:\Python37-32\Scripts\? ?C:\Python37-32\ ``` 確保PYTHONHOME是C:\Python37-32 保存設置
