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 nodejs

npm 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

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!
