使用pip3在Centos7上安装ansible

Question

我已经安装了ansible版本2.9.25（centos的最新版），但它\xe2\x80\x99s无法使用\xe2\x80\x98get_url\xe2\x80\x99模块下载文件，而我谷歌搜索的所有内容似乎都指向使用python2与 python3 相反。所以我尝试通过 pip3 安装 ansible，文档声称将使用 python3 安装 ansible 但给出 Unicode 错误：

我运行的命令尝试修复：

\n

pip3 install setuptools_rust\npip3 install --upgrade pip\npip3 install ansible \nsudo yum install gcc libffi-devel python3-dev python-devel openssl-devel\nsudo yum install -y git python-devel python-pip gcc gcc-c++\n\n

我尝试过的其他解决方案：\n https://github.com/paramiko/paramiko/issues/1027#issuecomment-371754576

\n

当前设置：

\n

# pip --version\npip 21.2.4 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)\n# pip3 --version\npip 21.2.4 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)\n# python --version\nPython 2.7.5\n# python3 --version\nPython 3.6.8\n

\n

如果我可以提供任何其他信息，请告诉我！

我也有过类似的错误。控制台/终端必须使用 UTF-8 语言环境，而不是 ASCII。将环境变量LC_CTYPEor设置LC_ALL为C.UTF-8or en_US.UTF-8：

LC_CTYPE=en_US.UTF-8
export LC_CTYPE

安装后ansible可用于任何语言环境。仅安装需要 UTF-8。
