在 Alpine Linux Docker 圖像上，我得到“nvm：找不到命令”

Question

I have read the README of the nvm project, which lists the packages I need to install, although I had to modify the python2 package to python3 , since the former package was deprecated following Alpine 3.13 release, as node can run on python3 package. 這是我的 Dockerfile，它是我的.devcontainer目錄的一部分，可以在代碼空間上運行：

# Pull the Alpine 3.15 Docker image
FROM alpine:3.16

# Enter the BASH shell
ENTRYPOINT [ "/bin/bash" ]

# Add packages without caching, but while upgrading Alpine
RUN apk add --no-cache -U\
    curl bash ca-certificates\
    openssl ncurses coreutils\
    python3 make gcc g++\
    libgcc linux-headers grep\
    util-linux binutils findutils

RUN touch ~/.bashrc

# Install NVM and source it
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
RUN echo '\
export NVM_DIR="~/.nvm" \
[-s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" \
[[ -r $NVM_DIR/bash_completion ]] && \. $NVM_DIR/bash_completion\
' >~/.bashrc

# Run the usual setup NVM commands
RUN [ "/bin/bash", "-c", "nvm install -s --lts --latest-npm" ]
RUN [ "/bin/bash", "-c", "nvm alias default lts/*" ]

# Install NPM packages and run the dev server
RUN [ "/bin/bash", "-c", "npm i" ]
CMD [ "/bin/bash", "-c", "npm run dev" ]

這是我的creation.log文件中表示錯誤的行：

2022-09-27 14:44:57.546Z: #9 [6/8] RUN [ "/bin/bash", "-c", "nvm install -s --lts --latest-npm" ]
2022-09-27 14:44:58.134Z: #9 0.539 /bin/bash: line 1: nvm: command not found
2022-09-27 14:44:58.229Z: #9 ERROR: executor failed running [/bin/bash -c nvm install -s --lts --latest-npm]: exit code: 127

如果還需要什么，請告訴我！ 謝謝你的幫助！

我不會為 python 應用程序使用基於alpine的圖像，

標准 PyPI 輪子在 Alpine 上不起作用

如今，大多數 Python 軟件包都包含 PyPI 上的二進制輪，大大加快了安裝時間。 But if you're using Alpine Linux you need to compile all the C code in every Python package that you use.

你最終可以解決這個問題，然后另一個會出現，依此類推......
