使用reflex的序章：安装cargo、fnm和bun
安装好reflex后，需要安装好cargo和fnm
安装cargo
apt install cargo设置加速镜像
在.cargo/config文件里写入：
[source.crates-io]
replace-with = 'mirror'
[source.mirror]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"安装margo的新版本
sudo npm install major
安装fnm
cargo install fnm
设置npm的加速镜像
npm config set registry https://registry.npm.taobao.org/
使用镜像源可以加快npm包的下载和安装速度，尤其是在国内网络环境下。你可以通过设置npm的配置来切换镜像源。例如，要使用淘宝源，可以执行以下命令：
npm config set registry https://registry.npm.taobao.org/
或者要使用cnpm源，可以执行以下命令：
npm config set registry http://r.cnpmjs.org/
切换镜像源后，再使用npm安装包时，npm将会从对应的镜像源下载和安装包。
npm update
有些慢，感觉卡住了
发现Node版本不一致，报错信息里显示要用18.17，手工下载安装
# installs fnm (Fast Node Manager)
curl -fsSL https://fnm.vercel.app/install | bash
# activate fnm
source ~/.bashrc
# download and install Node.js
fnm use --install-if-missing 18
# verifies the right Node.js version is in the environment
node -v # should print `v18.20.4`
# verifies the right npm version is in the environment
npm -v # should print `10.7.0`reflex需要的是18.17 ,这个下载不下来。手工下载install文件，执行后github下载fnm失败。
升级nodejs
sudo apt upgrade nodejsnpm 设置镜像
(base) skywalk@ub:~/app1$ npm config set registry https://registry.npmmirror.com
(base) skywalk@ub:~/app1$ npm config get registry
https://registry.npmmirror.com
(base) skywalk@ub:~/app1$ npm update

run `npm fund` for details
安装rustup
安装rustup
sudo snap install rustup --classic然后升级到nightly版本
rustup install nightly
rustup default nightly升级后还是无法安装bun
手工安装bun
curl -fsSL https://bun.sh/install | bash
手工安装bun 失败，主要是github有问题。
尝试手工npm 安装bun
sudo npm install -g bun 安装成了。
结论：
因为特殊的国情，涉及到github自动下载安装的部分存在很大的坑，导致cargo 安装bun会失败，进而导致reflex init会失败。
解决的方法：
cargo升级到最新，npm最新，rustup 设为nightly
rustup install nightly
rustup default nightly若cargo安装bun失败，curl安装bun失败，可以尝试使用npm安装bun 。
sudo npm install -g bun 调试

还会用cargo install fnm试试

使用cargo install bun试试
安装bun报错error: failed to compile `bun v0.1.0`,

To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.
Error: Pear requires a 'dev' or 'nightly' version of rustc.
安装rustc rustc-1.76 试试
不行，
安装rust-all试试
sudo apt install rust-all
然后安装rustup
sudo snap install rustup --classic然后升级到nightly版本
rustup install nightly然后再来安装bun
还是一样的报错
手工安装bun
curl -fsSL https://bun.sh/install | bash
安装失败，主要是github有问题。
手工npm 安装bun
sudo npm install -g bun
安装margo的新版本
sudo npm install major
安装之后，再安装bun，还是一样失败。
实在搞不定，放弃。
后来一通整，bun这边竟然过去了。也就是执行reflex init 通过了！
