这两天准备折腾Hermes，有几台服务器，正好用起来。服务器都用的CentOS。

查看了一下Python和node的版本，yum update之后，python –version为3.8.6，node –version 为20.15.0，python版本不够，需要更新。

干脆安装一下版本管理器，管理多个版本吧。按照搜索到的指令执行：

git clone https://github.com/pyenv/pyenv.git ~/.pyenv
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
exec $SHELL
pyenv install 3.12

执行最后一步时，是去下载https://www.python.org/ftp/python/3.12.13/Python-3.12.13.tar.xz文件并安装，结果是下载失败，报如下错误：

pyenv install 3.12

询问Gemini后，提示是缺少必要的包的问题，给了两种方案，一种是设置忽略安全验证直接安装，一种是安装必要的依赖。我采用了安装必要依赖的方案。在服务器上执行如下脚本：

sudo dnf install -y gcc make zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel tk-devel libffi-devel xz-devel

上述指令执行成功后，再次执行python12的安装指令：pyenv install 3.12

一台机器上执行成功，另外一台失败。执行成功的机器上，执行pyenv 3.12.13之后提示成功，但是执行python –versioin 的时候，仍然是旧版本，后来查询之后，发现需要执行指令：eval “$(pyenv init -)” ，source ~/.zshrc。执行此指令之后，再执行查看版本指令，现在对了。

参考文章《https://cloud.tencent.com/developer/article/2671206》来安装Hermes

1、克隆项目 git clone https://gitcode.com/GitHub_Trending/he/hermes-agent.git

2、将代码复制到安装目录

mkdir -p ~/.hermes
cp -r ~/hermes-agent ~/.hermes/hermes-agent

3、进入到安装目录并执行安装

cd ~/.hermes/hermes-agent && bash scripts/install.sh

我执行完这一步之后，日志出现如下信息：

✓ Main package installed (hash-verified via uv.lock)

✓ All dependencies installed

→ Installing Node.js dependencies (browser tools)...

⚠ npm install failed (browser tools may not work)

✓ Node.js dependencies installed

→ Installing browser engine (Playwright Chromium)...

⚠ Playwright does not support automatic dependency installation on alinux.

→ Install Chromium/browser system dependencies for your distribution, then run:

→   cd /root/.hermes/hermes-agent && npx playwright install chromium

→ Browser tools will not work until dependencies are installed. 

问Gemini，提示让执行一些指令来安装依赖，执行了如下指令：

安装chromium底层依赖：yum install -y nss alsa-lib atk at-spi2-atk cups-libs libdrm \
libXcomposite libXdamage libXext libXfixes libXrandr mesa-libgbm \
pango cairo libxshmfence

手动安装PlayWright chromium：npx playwright install chromium

安装完成后，再次执行harmes的安装指令，这次能正常完成了。
