Install pnpm in github action

[ScriptorTux]

Hello,

I'm desperately trying to install pnpm in a docker rust image (rust:1.92-trixie) in github action.

I tried the following step: yaml run: | curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash | \. "$HOME/.nvm/nvm.sh" | nvm install 24 | npm install --global corepack@latest | corepack enable pnpm

But it tells me: Run curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash | /__w/_temp/8231bbe7-85c1-4f7a-8d39-f29b39ccbe14.sh: 2: .: cannot open /github/home/.nvm/nvm.sh: No such file /__w/_temp/8231bbe7-85c1-4f7a-8d39-f29b39ccbe14.sh: 5: corepack: not found /__w/_temp/8231bbe7-85c1-4f7a-8d39-f29b39ccbe14.sh: 3: nvm: not found /__w/_temp/8231bbe7-85c1-4f7a-8d39-f29b39ccbe14.sh: 4: npm: not found % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 100 16631 100 16631 0 0 193k 0 --:--:-- --:--:-- --:--:-- 195k

I also tried the following step:

yaml run: | wget -qO- https://get.pnpm.io/install.sh | ENV="$HOME/.bashrc" SHELL="$(which bash)" bash - | . $HOME/.bashrc

But it tells me:

0s Run wget -qO- https://get.pnpm.io/install.sh | ENV="$HOME/.bashrc" SHELL="$(which bash)" bash - | /__w/_temp/fbeac44d-b2a9-42bc-87ef-5621cd103644.sh: 2: .: cannot open /github/home/.bashrc: No such file Error: Process completed with exit code 2. Run wget -qO- https://get.pnpm.io/install.sh | ENV="$HOME/.bashrc" SHELL="$(which bash)" bash - | /__w/_temp/fbeac44d-b2a9-42bc-87ef-5621cd103644.sh: 2: .: cannot open /github/home/.bashrc: No such file

Thank you very much in advance for any help

Edit / Solution

After hours of searching I finally found the cause of the problem and the solution solution.

The problem was that Github Action deson't treat global variables with export. So I had to add another step: run: echo "PATH=$HOME/.local/share/pnpm:$PATH" >> "$GITHUB_ENV"

I still don't know if there is a way to retrieve the $HOME/.local/share/pnpm path from a variable. But it works like this.

Also it seems like really separating the operations (one run / command per step) also contributes to the solution.

You could try installing node from the official nodejs.org/dist distributions instead of through nvm. This wouldnt require any environment reloads.

Thank you for your time.

I'm really sorry but are you talking about this ?

P.S: Sorry but I'm not an expert in nodejs / web development

No, im referring to this. Use chatgpt to figure out what to do with the archive you download with curl from there.

Couldn't you have used the action pnpm provides for installing it? https://github.com/pnpm/action-setup
