shards install gives incompatible dependencies when installing from sources

[nilslindemann]

In order to be up to date with changes made in this repo, i was just trying to install Mint from sources.

I installed the Crystal compiler this way (and not this way because of this), on a recent Linux Mint.

I added two symlinks to crystal and shards.

sudo ln -s /home/nils/run/crystal-1.0.0-1/bin/crystal /usr/local/bin/crystal
sudo ln -s /home/nils/run/crystal-1.0.0-1/bin/shards /usr/local/bin/shards

After doing this, crystal --version gives 1.0.0, and shards --version gives 0.14.1.

Now i proceeded as described here -> Install from source, but the third command, shards install gives the following output and i am not sure how to proceed (Crystal is new for me). Should i use --ignore-crystal-version or should i try to update these seemingly incompatible shards, and if so, how do i do this? Any hints appreciated.

Here is the output of shards install:

Should i use --ignore-crystal-version

@nilslindemann until this is resolved upstream, yup

[nilslindemann]

Thanks, @Sija, I succeeded.

I installed it on a fresh Linux Mint. Six packages + Git were needed.

sudo apt install libyaml-dev libevent-dev libxml2-dev libssl-dev libpcre++-dev libz-dev git

To anyone reading this, check if these are installed before you run the build command. Because this needs a while (20 minutes on my machine) and it will report some of these packages, if they are missing, near the end.

And then, like in the docs:

cd ~/run
git clone https://github.com/mint-lang/mint.git
cd mint
shards install --ignore-crystal-version  # make shards happy
crystal build src/mint.cr -o mint -p --release --no-debug
chmod +x ./mint
sudo mv ./mint /usr/local/bin/mint

And test it:

cd ..
mint init helloworld
cd helloworld
mint install
mint start

Haha, 404, that issue number fits :-)

Once all these PRs are in, there should be no Crystal version issues:

• Replace time_format shard with TimeFormat module #421
• Replace tree_template with ECR #423
• Remove unused string_inflection shard #424
• Remove diff shard #425

For having several Crystal 1.0 issues, it probably couldn't have been better. All of the shards were either unused or easily replaced!

@Sija if you want to unpin this, it is no longer an issue

[Sija]

@matthewmcgarvey Good point, done!
