No root table found for toml file

[f-fr]

When running cargo graph on an arbitrary project I receive the following error message:

% cargo graph
error: No root table found for toml file

I have no idea what this error means or how I can get more information about the problem. Any ideas?

This is caused by recent changes to Cargo. #38 fixes the issue.

unfortunately cargo install still installs an older version - could you push a new one?

[shaleh]

Yes please. I came to submit the same issue.

[aochagavia]

Same here

Until a new version is pushed, you can add the following to your Cargo.lock to get around the issue temporarily.

[root]
name="your-package-name"

Doing so will cause other cargo commands to fail, however. That's because future/current cargo will see that as duplicating the project definition.

@ChristopherMacGown Thanks for the tip!

I had to add version as well to Cargo.lock, like so:

[root]
name="your-package-name"
version="package-version"

worked like a charm.

cargo +nightly install --git https://github.com/kbknapp/cargo-graph --force worked for me.

[chisophugis]

I just tripped on this. What is the status? According to the earlier comment #38 fixes this, which was merged like 6 months ago.

Ditto, ended up going with the forced git install.

[crawford]

Bump.

[spearman]

Is this the same as error: No name for package in toml file ?

[Boscop]

Any update on this?

I was able to get it going by following steps on a CentOS 7 OS.

• check out cargo-count repo.

  [[pi@centos7 cargo-count]$ pwd
  /home/pi/gb/cargo-count
  [pi@centos7 cargo-count]$

• commands

  
  sudo yum install -y graphviz
  git clone https://github.com/kbknapp/cargo-graph && cd cargo-graph
  cargo build --release
  cargo install  --force
  cd ../cargo-count/
  cargo graph  --optional-line-style dashed --optional-line-color red --optional-shape box --build-shape diamond --build-color green --build-line-color orange > cargo-count.dot
  dot -Tpng > rainbow-graph.png cargo-count.dot

[pi@centos7 cargo-count]$ ls -l *.png -rw-rw-r-- 1 pi pi 59023 Feb 21 07:00 cargo-count.png -rw-rw-r-- 1 pi pi 144496 Feb 21 07:10 rainbow-graph.png [pi@centos7 cargo-count]$

You can use my fork instead, which includes the fix for this (as well as for many, many other bugs), plus has some new features (plus is actually maintained).

cargo install cargo-deps

See the new features with

cargo deps -h

[tjyang]

Thanks @m-cat for your pointer. I will follow cargo-deps instead.

[pi@centos7 cargo-deps]$ cargo  deps -h
