如何在 64 位 Amazon Linux 2 上为 Elastic Beanstalk Python 3.7 项目 运行 安装节点包？
How to install Node Packages for an Elastic Beanstalk Python 3.7 Project Running on 64bit Amazon Linux 2?
我正在使用名为 django-pipeline 的 Django 包来压缩 js 和 css 文件。
当我部署我的项目时，我 运行 Django 的 collectstatic 命令，来自 .ebextensions 文件夹：
01_django.config:
container_commands:
...
07_collectstatic:
command: "source /var/app/venv/*/bin/activate && python3 manage.py collectstatic --noinput"
问题是，django-pipeline 使用需要 Node.
的压缩器库
我复制了两个库（cssmin 和 terser）from 我的 node_modules 本地目录 到 我的 static 目录。
static
|_vendor
|___|.bin
|_____|cssmin
|_____|cssmin.cmd
|_____|terser
|_____|terser.cmd
|___|cssmin
|_____|...
|___|terser
|_____|...
其次，我在管道上设置了以下设置来告诉管道二进制文件存在的位置：
PIPELINE_CONFIG.update({
'CSSMIN_BINARY': os.path.join(BASE_DIR, "static", "vendor", ".bin", "cssmin"),
'TERSER_BINARY': os.path.join(BASE_DIR, "static", "vendor", ".bin", "terser"),
})

我的问题
如何在 Python 3.7 Elastic Beanstalk 环境中安装节点，以便这个 collectstatic 命令可以工作？
编辑 #1
我试过：
commands:
05_install node:
command: |
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
. ~/.nvm/nvm.sh
nvm install node
它returns同样的错误：
pipeline.exceptions.CompressorError: b'/var/app/staging/static/vendor/.bin/cssmin: line 12: node: command not found\n'
出现错误的 cssmin 文件如下所示：
#!/bin/sh
basedir=$(dirname "$(echo "[=19=]" | sed -e 's,\,/,g')")
case `uname` in
*CYGWIN*) basedir=`cygpath -w "$basedir"`;;
esac
if [ -x "$basedir/node" ]; then
"$basedir/node" "$basedir/../cssmin/bin/cssmin" "$@"
ret=$?
else
node "$basedir/../cssmin/bin/cssmin" "$@" <----------- line 12
ret=$?
fi
exit $ret
我已经尝试了 prebuild hooks:
#!/bin/bash
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
source /root/.nvm/nvm.sh
nvm install node
export NVM_DIR="/root/.nvm"
node -e "console.log('Running Node.js ' + process.version)"
来自 Elastic Beanstalk 的 eb-hooks.log 中预构建挂钩的结果：
2021/09/14 15:13:59.896274 [INFO] => nvm is already installed in /root/.nvm, trying to update the script
=> nvm source string already in /root/.bashrc
=> bash_completion source string already in /root/.bashrc
=> You currently have modules installed globally with `npm`. These will no

=> with `nvm`; and they may (depending on how you construct your `$PATH`)
=> override the binaries of modules installed with `nvm`:
/root/.nvm/versions/node/v16.9.1/lib
+-- corepack@0.9.0
=> If you wish to uninstall them at a later point (or re-install them under your
=> `nvm` Nodes), you can remove them from the system Node as follows:
$ nvm use system
$ npm uninstall -g a_module
=> Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Now using node v16.9.1 (npm v7.21.1)
Running Node.js v16.9.1
上面的输出显示节点已安装，但我的 collectstatic 容器命令仍然失败，无法找到节点。
失败后，我可以SSH进入实例，看到定位nvm的环境变量存在：
declare -x NVM_BIN="/root/.nvm/versions/node/v16.9.1/bin"
declare -x NVM_CD_FLAGS=""
declare -x NVM_DIR="/root/.nvm"
当我在 container_commands:
中 运行 which node 时，我得到了一个有趣的输出
2021-09-14 16:40:46,512 P8087 [INFO] which: no node in (/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin)

2021-09-14 16:40:46,512 P8087 [ERROR] Exited with error code 1
那个时候节点似乎不在系统路径上？
您可以使用 commands 并执行以下操作：
更新：
commands:
05_install node:
command: |
curl -sL https://rpm.nodesource.com/setup_16.x | sudo bash -
yum install -y nodejs
