Some possibility of installation

[hydrogencl]

Dear community, and possible people suffering as well,

I also have struggles for installing basemap, especially with python3.6 (default shipped with Ubuntu 18.04)
After several tries like using cartopy, using apt install to install cartopy and basemap. None of them works quickly for python3.6.

In the end it works for this "simple" way:

1. Installing pyproj (3.0.0) by python3 -m pip install pyproj==3.0
2. installing matplotlib by python3 -m pip install matplotlib==3.3.3
3. downloading the basemap 1.2.2 version and install also by python3 -m pip install . in the basemap untar folder.

Hope this helps.

Hi @metalpen1984,

Yes, you are totally right, at the moment it is not so easy to install due to the basemap dependencies. I am working on it but the solution is still not finished.

You could also try some temporary wheels that I have in my fork. These wheels already handle the installation of the Python dependencies, but it still lacks the pre-built libgeos shared library inside in order to have proper manylinux1 packages. I am also working on it.

With these wheels you would need to install first GEOS by yourself (sudo apt-get install libgeos-dev), ensure that you have gcc installed too, and then python3 -m pip install for the wheel files.

Please note also that I have split basemap in several packages there:

• basemap-lite: the basemap Python source code, it depends on basemap-data so you need to install it first.
• basemap-data: most of the files in the data folder.
• basemap-extras: the bulky high-resolution data files. This wheel is optional if you do not need the high-resolution files. It is kind of like basemap-data-hires in Anaconda.

can not install basemap for two days, and i tried many times, who can help me out, thanks.

@LiXingguangBrandonStark Unfortunately for Mac I cannot help you much because I do not have a computer with it. I would like to provide wheel files in the future for Windows, Linux and Mac, but I haven't had time yet.

The most likely reason why your installation does not work is because it cannot compile the _geos extension, probably because it cannot find the geos_c shared library. Do you have GEOS installed in your system? Are you trying to compile GEOS from the source code provided with basemap?

[liamxg]

anyone install basemap in MAC?

[molinav]

Sorry, the geos I was referring to is not the one that you can see in PyPI (and listed with you pip list command), it should be a shared library that e.g. under Ubuntu it can be installed with apt-get. If it is not available through repositories, you would need to compile it from source before installing basemap. The source code of GEOS is provided together with basemap.

Are you using Anaconda? Are you using Homebrew?

[liamxg]

i can use both of annacoda and homebrew.

Under Anaconda, isn't it working if you do conda install -c conda-forge basemap? Then you avoid having to compile GEOS by yourself, I guess Anaconda has its own GEOS shared library already.

[liamxg]

i use both python3 -m pip install geos, and cd geos-3.3.3
export GEOS_DIR=

A reasonable choice on a Unix-like system is /usr/local, or

if you don't have permission to write there, your home directory.

./configure --prefix=$GEOS_DIR
make; make install

[liamxg]

but still not work

[liamxg]

is there anyone install basemap using mac that are worked out, thanks.

[liamxg]

@molinav can i email you, thanks. This is very important to me.

[molinav]

Sure, just write me.

[liamxg]

thanks.

[liamxg]

@molinav i have sent the email to you, if you have received my email, please let me know, this is very important to me, thanks.

@metalpen1984 i used your method in mac, but still not work out when i run "python3 -m pip install ."

[liamxg]

@metalpen1984 any suggestions?

[molinav]

The problem in the end was the absence of basemap for Python 3.9 under Anaconda. Using a virtual environment with an older Python version (e.g. Python 3.8) was enough to install basemap by means of conda without problems.

Sorry for this really late reply, however my solution only works for Linux (if possible). Recently I just reinstall all the stuff on Ubuntu 20.04, and one fix should be applied since there is a ISNAN caused likely by DEBIAN/UBUNTU system: set export CXX="g++ -std=c++98" before installing the attached GEOS-3.3.3 in the source code.

@hydrogencl For your information, basemap version 1.3.0 is finally available in PyPI. With this version, we provide precompiled binary wheels for Windows and GNU/Linux. You can give it a try by installing as usual with pip:

python -m pip install basemap
